Bearings and materials

Bearings and materials

The pressed steel bearing seats and internal rings of the ballbearing are hardened and galvanized zinc-plated. The shape ofthe ball bearing is designed specifically for conveyor rollers andtolerates greater deflection of the bearing than comparable
precision ball bearings.

The standard version bearings are precision ball bearings 6205
2RZ or 6204 2RZ. Depending on the series, the drive elements,
such as sprockets or toothed belt drive heads, are made offiberglass-reinforced polyamide and polyoxymethylene or steel.
The bearing housing on the non-driven side and the seals are
made of polyamide.

Platform 1700

For universal use
For particularly quiet conveyance at high speeds
For lightweight and medium-heavy materials to be conveyed
For driven and non-driven conveyors

Properties
Platform 1700 is designed for high loads at very low noise levels
and provides the ultimate in flexibility with its different drive
options. The bearing design comprising polyamide bearing
housing, precision ball bearing and a polypropylene orpolyamide seal produces an extremely quiet conveyor roller,
which can simultaneously carry heavy loads. Bearing housingsand belt drive heads are installed in the tubes in a form-fit way(flanging for steel tube and press-in edge for polymer tube). The
unique feature about this platform 1700 is the tapered shaftshuttle, which combines the benefits of a female threaded shaft
and a spring-loaded shaft (cf. shaft-shuttle shaft design
page 13).

Sealed DIN precision ball bearings 6002 2RZ, 689 2Z and
6003 2RZ are used. They are greased with a silicon-free lubricant
and have a secure bearing housing in the base of the roller
thanks to a snap-on edge. In addition, the ball bearing 6002 2RZ
is oiled or available in a stainless steel design.
The integral polypropylene seal is fixed in the internal ring of theball bearing and has three functions: Protection of the ballbearing against coarse dirt and splashing water, diametercompensation of shaft and internal ring as well as diverting axial
forces into the ball bearing.

Bearings
Interroll utilizes different bearings, such as slide bearings or
special ball bearings made of polypropylene with steel balls.
However, the following section describes only the precision ballbearings used by Interroll.
Further information on the bearing assemblies (ball bearings withbearing housings and seals) is provided in the Platforms chapter(Platforms) and under Material Specification (Material
specification).
All precision ball bearings used are designed as 2RZ, except for
type 689. The steel sealing discs form a narrow sealing gap, but
are non-contacting. They ensure an optimal startup of the roller.
The steel-reinforced rubber sealing lips (NBR) lie against the innerring under external pressure and thus provide an exceptional
sealing quality comparable to the 2RS version. The oil-lubricatedversion is characterized by its easy start and exceptional easyrunning properties.

GENERAL TECHNICAL INFORMATIONSHAFTS

Shafts
Shaft materialInterroll offers shafts made of three different materials or
finishings:· Uncoated steel· Zinc-plated steel· Stainless steel
All shafts are manufactured from cold-drawn steel.
Interroll recommends to match the shaft material to the materialof the side profile.

· With driven rollers, play between the shaft and the mounting
hole (inevitably due to oblique installation) will create noise,
particularly when starting and stopping the turning motion(especially at hex shafts).
· Depending on the selection of material pairing (shaft/side
profile) and dimensions (size of hole and spring-loaded shaft), it
may lead to wear of the shaft (hexagon looses its edges) or theside profile.
· Shield for zinc-plated shaft material is not zinc-plated
Female threaded shaft

Zinc-plated shafts are cut from galvanized zinc-plated rod
material, thus the front faces of the female threaded or springloaded shafts are always without zinc plating.
Male threaded shafts cannot be zinc-plated, otherwise they posea risk of blocked threads due to the zinc layer. For this reason,
Interroll recommends selecting either male threaded or flatted
shafts in stainless steel to obtain adequate corrosion protection.

Manufacturing process
After the sawing process, the shafts are milled. Milling reduces
deformations of the shaft ends or damages on the side profile
during installation to a minimum. Furthermore, milling removes
sharp burrs, thereby ruling out a risk of injuries. Hence, thiscreates not only safe, but also perfectly manageable rollers.
For threaded holes, the centering holes are drilled in a first step
to ensure precisely centered threaded holes in the shaft.

Versions

Female threaded shafts can be manufactured from roundmaterial or hex material.
· Lead to a very stable frame construction – generally, no use ofcrosslinks is required· A firm connection causes a lot less noise than shafts that are
not firmly screwed together.
· The roller shaft and side profile stabilize each other resulting in
the conveyor rollers having a greater load capacity thanloosely fitted rollers.
· Wear-free towards spring-loaded shafts due to firm connectionin the side profile· Medium-fast installation and removal· Shield for zinc-plated shaft material not zinc-plated· Safe discharge of static charges (anti-static design)

Spring-loaded shaft

Spring-loaded shafts can be manufactured from round material
or hex material.
· Simple shaft design· Very fast and simple installation and removal· Suitable crosslinks have to be provided between the side
profiles to reinforce the conveyor.

Male threaded shafts feature a thread cut onto the shaft ends. In
each case, a nut is screwed onto the shaft in front of the seal. The
two nuts are subtracted from the dimension of the "lane width"
during the production of the roller. They shorten the usable lengthof the roller compared to rollers with female threaded shafts.

Shaft with shaft-shuttle

Shafts with shaft-shuttle are made of 8-mm hex material. Bothends are fitted with the shaft-shuttle made of polyamide. The
conical shaft-shuttle reduces the hex surface towards the shaft
end.
· Very fast and simple installation and removal· Similar low noise level as female threaded shafts· Wear-free towards spring-loaded shafts due to zero-clearance
seating of the shaft free in the side profile (11 mm hex hole,+0.3/+0.8 mm)· Anti-static version· Particularly suited for modernizing systems; side profiles thathave been in use for a long time generally show hightolerances in the holes· Evenly aligned, anti-rotation shuttles (positioning one side issufficient)· Both shaft ends can be pushed in· Suitable crosslinks have to be provided between the side
profiles to reinforce the conveyor· No scratching of high-quality side profiles during installation
and removal· A firm connection causes a lot less noise than shafts that are
not screwed together· Very stable frame construction – generally, no use of crosslinks
is required· The roller shaft and side profile stabilize each other resulting in
the conveyor rollers having a greater load capacity thanloosely fitted rollers.
· Wear-free towards spring-loaded shafts due to firm connectionin the side profile· The two nuts at the seal and two nuts with washers forfastening are part of the scope of delivery· Available only in the versions uncoated steel or stainless steel
Flatted shaft

Flatted shafts are made of round material. They have two lateral,
parallel milled sections at the shaft ends, which fit into
corresponding side profile holes, e.g. into side profiles with open
longitudinal holes.
· Very fast and simple installation and removal· Suitable crosslinks have to be provided between the side
profiles to reinforce the conveyor.
· Lower noise level than spring-loaded shafts since only minor
play is required (no oblique installation)© 07 | 2023 Interroll

· Shields, or flat shafts if needed, are not zinc-plated for zincplated shaft material.
· Simple shaft design· Very fast and simple installation and removal with fastening
holes open to the top· Suitable crosslinks have to be provided between the side
profiles to reinforce the conveyor· With driven rollers, play between the shaft and the mounting
hole will create noise, particularly when starting and stopping
the turning motion. For this reason, Interroll recommends thelowest play possible.

The following formula and the drawings should provide support insufficiently dimensioning the fastening hole. For this purpose, anoversize of 0.5 mm of d1 compared to the shaft diameter issufficient in most cases. In case of side profiles with different
heights, the dimension H of the higher profile must always be
used for the calculation.

H

Fixed shafts can be manufactured from hexagon or roundmaterial. It is possible to fit the round shafts with a flat shaft. The
shafts are mostly inserted in fastening holes in the side profile thatare open at the top. To rule out that the shaft turns inside theguide of the side profile, Interroll recommends the use of hexagon
shafts or round flatted shafts in corresponding side profiles
intended for this purpose.

Installation instructions
The following should be considered in relation to the selection ofa shaft and construction of the side profiles:

3.

14

d

2.

The hole dimension of the side profile should be as small as
possible on conveyor rollers with female threaded shafts.
Larger holes can lead to a higher tolerance of the roller pitch
and to the height differences of several conveyor rollers. The
function of the roller conveyor can be affected by the holeand screw selection.
For softer side profiles made out of aluminum or thickpowder coatings, female threaded shafts should always be
selected with the largest possible diameter and the smallest
possible thread. This minimizes the risk of the shaft
penetrating the aluminum profile.
The installation of conveyor rollers with spring-loaded shaft
must be done in an oblique way. That is the spring-loaded
shaft must be inserted in a hole of the side profile.
Afterwards, the other roller end is moved from an oblique to

Labeling
All shafts starting with a length of 100 mm are labeled with therespective production order number. The number is located on
the shaft inside the tube. It allows users to order an identicalroller without having to provide information about the product,such as the length.

Example: At the time of ordering, a lane width (EL = installation
length) of 500 mm is specified for a roller of series 1700 withfemale threaded shaft. The dimension from seal to seal measuresapprox. 499 mm. Hence, the roller has an axial play of
approx. 1 mm (see figure above).

Conveyor rollers must not be warped during installation oroperation. This means that play must exist between the seal of theroller and the side profile. The roller must move in axial direction
under load.
The axial play must not be too high. Rollers with tapered shaftshuttle or RollerDrive with tapered spring-loaded shaft aredesigned so that they have the best possible fit for the hole in theside profile, even in cases of high hole tolerances. This reduces
wear and possible noise. If the axial play is too high, it may pose
the risk of insufficient positioning of the hexagon in the hole,which leads to wear and noise.

The axial play under consideration depends on roller series androller version. For example, an axial play of approx. 1 mm on thedrive side and 0.5 mm on the other side is taken into account fora roller of series 3500 with sprocket head (see figure above).
The axial play stated is only a guide value. There may be slightdeviations from this figure in individual cases when production
tolerances are added. The function of a correctly installed andused conveyor roller is not being impacted.

Variable shaft length
A deviation of the standard shaft length is possible for all roller
series. The shafts can be shortened or lengthened. The axial
support of a roller via the seal must be ensured at all times. For
some roller series, this requires taking appropriate measures incase of a shaft lengthening.

The maximum play is already taken into account during the
manufacture of the rollers.

The length changes depend on the actual shaft version. Please
direct any questions to your Interroll contact person. Axial
support by the seal may no longer be guaranteed with a lengthchange. With greater axial forces, e.g. where there is lateraldisplacement, suitable replacement structures, such as spacing
tubes, may have to be fitted.
With female threaded shafts, the shaft can be lengthened only if
the seal is given an axial support. Depending on the thread andshaft diameter, a retaining ring can be inserted. The retaining
ring is secured via a groove incorporated in the shaft. The
combination of a female threaded shaft with flatted shaft also
requires a support of the seal.
In case of a shaft lengthening, the maximum load capacity of theroller is reduced compared to the values that are specified foreach side.

Shaft adapter

The shaft adapter can be used with the following roller series:

The shaft adapter is a conductive polymer component that can bepressed onto roller shafts. It can be inserted in side profiles with
open elongated holes. In this case, the roller is placed from thetop. The shaft adapter significantly reduces the noise levelcompared to the pure steel shaft and increases the installation
length of the roller. The shaft adapter is not an alternative to thetapered shaft-shuttle (page 13).

The steel tubes used by Interroll are manufactured in accordancewith DIN EN 10305-1, DIN EN 10305-3 and DIN EN 10296-2
but with stricter tolerance specifications.
The roller manufacturing and transport may result in minor
scoring or scratches to appear on the tube surface. However,they do not have any effect on the functionality of the roller.
Benefits· Highest resistance and bending stiffness· Steel – corrosion protection through zinc-plating or
carbonitriding· Stainless steel – very good and long-life corrosion protection· Stainless steel – Application also possible in aggressive
environments (not suitable for seawater)· Sprockets and flanges can be welded on (flanges not together
with stainless steel tube)© 07 | 2023 Interroll

Versions· With grooves (not for carbonitrided tube)· Covered with PVC or PU sleeve· With lagging· With pushed-on tapered elements· With flanges welded on
When used in belt conveyors, there is noise caused by the paredtube welds coming into contact with the belt. Interroll
recommends testing the relevant application.
Aluminum
Aluminum tubes have slightly lower strength and only about 33 %of the flexural strength of steel tubes. However, they weigh only
36 % of the weight of comparable steel tubes.
Benefits· Significantly lighter than steel tube
· Corrosion-resistant· Aluminum tubes can be flanged over the bearing assembly sothat the bearing housing can no longer move out

PVC
Benefits· Noise-dampening· Highly impact-resistant· Very lightweight· Corrosion-resistant, no surface treatment required· Easy to clean
Polymer tubes have a significantly lower load capacity comparedwith steel and aluminum tubes with the same diameter.
With polymer tubes with a diameter of 30 mm and larger, thebearing assemblies are connected form-fit with the tube so that
an absolutely safe seating is ensured.
An ambient temperature range from −5 to +40 °C applies topolymer tubes. With a high ambient temperature (from 30 °C)
and high continuous static load (over hours), a permanent
deformation of the rollers cannot be ruled out.
When dimensioning the rollers for an existing width between theside profiles (lane width), a thermal expansion must be taken into
account. In case of large temperature differences, the length of
the roller changes based on the following formula:∆LT = 0,08 ∙ L ∙ ∆T

Properties
Zinc-plated tubes are suitable for flanging and applying grooves.
The galvanized zinc-plating is a temporary protection of the steel
tube against corrosion.
The duration of the corrosion protection is reduced by themechanical and thermal loads to which it is subjected. Particles ofthe zinc layer may be carried off when transporting materials
over zinc-plated steel rollers.
Zinc-plated surfaces are sensitive to scratching and abrasion.
Damage can result in point corrosion.
Extreme changes in temperature must be avoided as they cancause internal tension. Furthermore, corrosion resistance becomes
reduced as the temperature rises.
In order to maintain the limited protective effects of zinc-plating,special packaging must be used for sea freight, for example.
Special measures must also be employed if the materials are to
be stored for a longer period of time. Zinc-plating is not foodcompatible.
A zinc-plated and passivated surfaced reacts with the following
substances:
·

Zinc-plating
Galvanized zinc-plating of steel tubes is a cost-efficient corrosion
protection.
Application· For dry application areas with normal temperatures· Conditional suitability for environments with salt and humidity,
e. g. installations in harbor areas or in sub-tropical countries· Conditional suitability in applications with moist or wet
materials
Besides zinc-plated tubes, Interroll also offers zinc-plated shafts
and zinc-plated sprocket heads. Front sides of shafts cannot be
zinc-plated.
Procedure
The surface of the steel tube material is galvanically zinc-plated(using electrolysis). The electrolysis produces an extremely even,thin sleeve. The entire process involves pre-treatment, zincplating, passivating and drying.

18

The long material is zinc-plated. When the tube is sawed off, thefront sides are not zinc-plated.
Carbonitriding
Carbonitriding is a wear-resistant corrosion protection for steel
tubes.

© 07 | 2023 Interroll

Properties
Carbonitrided tubes are partially suitable (up to 1.5 mm wall
thickness) for flanging, but not for the application of grooves.
The ceramic coating is a temporary protection of the steel tube
against corrosion. It is resistant to scratching and chafing.
Mechanical damage can result in point corrosion.
In addition, carbonitriding distinguishes itself with the following
properties:

Anodizing is a corrosion protection for aluminum tubes.
Application· For weight-sensitive applications, e.g. shuttle systems· For aluminum tubes with 20-mm diameter
Procedure
The surface of the aluminum tube is given an oxidic protective
coating. Compared to galvanizing procedures, the top material
layer is transformed and an oxide is formed.
Properties
The duration of the corrosion protection is reduced by themechanical and thermal loads to which it is subjected. Particles
may be carried off when transporting conveying goods overanodized rollers.
Anodized surfaces are low-sensitive to scratching and abrasion.
Mechanical damage can result in point corrosion.
An anodized surface can react with solutions of other metals,
such as copper, iron, etc.

GENERAL TECHNICAL INFORMATION
TUBES

Tubes with grooves

The load capacity information in the individual roller series refers
to rollers without grooves.
The maximum load capacity of the conveyor roller is lower withtube lengths of greater than 1400 mm. Interroll recommends a
shaft version that is secured against twisting for round belt drives,
such as a female threaded shaft. Grooves can be applied totubes with a wall thickness of up to 2 mm.
It is possible to apply one to four grooves for each tube. The
dimensions A ands up to D, as needed, must be specified
accordingly at the time of ordering. Version-dependent limitationsof the groove positions are located in the respective chapters of
the roller and RollerDrive series.

Grooves are running grooves that can be placed in steel tubes.
They are used to guide round belts. When using thecorresponding round belt, they are below the roller surface and,as such, do not contact the conveying good.
When the round belt is moved, the conveyor roller also moves.
Two options are differentiated here:

A

D
C

B
RL

· Wrap from roller to roller· Wrap of a driven shaft that is positioned below the conveyor
rollers. The guide rollers required for guiding the round belts
on the drive shaft are located on Series 2600.

Grooves reduce the concentric precision and load capacity of
conveyor rollers. A process-based enlargement of maximum 1
mm of the tube diameter is possible in the immediate vicinity ofgrooves. Interroll recommends conveyor rollers with round belt
drive heads or PolyVee drive heads of the Series 3500 to ensurethat concentric precision is adhered to (page 82).

General technical information

GENERAL TECHNICAL INFORMATIONPVC SLEEVE

PVC sleeve

The Interroll conveyor rollers can be manufactured in different
lengths utilizing millimeter increments. Most versions can be
manufactured starting at a length of approx. 200 mm. The
longest dimension for many series is approx. 2000 mm. The
shortest and longest dimension depends on many factors, such as
shaft design, tube material, production process or packaging
options.
Definitions= Reference length/ordering length= Installation length, inside diameter between side profiles= Total length of shaft= Usable tube length, length without bearing housing and forflanged metal tube without length of flanging

For conveyor rollers with female threaded shaft, the total shaft
length corresponds to the installation length.

The PVC sleeve ensures a particularly high noise reduction andoffers a high level of protection for sensitive conveying goods. An
improved conveyance of conveying goods is achieved with thehigher coefficient of friction compared with a steel tube.
Conveying goods can easily be separated since the larger
diameter leads to a higher speed with the same rotational speed.

Technical data

The installation length can be measured via the total shaft length
only for rollers with female threaded shaft. For all other shaft
designs, the installation length cannot be measured precisely at
the conveyor roller. The axial play of approx. 0.5 mm or at thedriven sides of approx. 1 mm is part of the installation length anddoes not allow an exact measurement of the installation length.

General technical data

The reference length/ordering length has measurable referenceedges on the conveyor roller for the following series:

Conveyor rollers with welded drive element can also be fittedwith a PVC sleeve. This requires a drive element whose diameter
is not greater than 12 mm of the tube.
Friction rollers (Series 3800, 3800 light, 3870) can be fitted onlywith 2-mm PVC sleeve. Rollers with PVC sleeve are always
designed with an antistatic element. The PVC sleeve is notantistatic.
The sleeve is a wear part. For example, sharp-edged or heavy
conveying goods with a structured bottom can wear out the tube
more quickly. The tube is unsuitable for very sharp-edged orpointed conveying goods or pallets with protruding nails.

Dimensions
The PVC sleeve generally covers the entire tube length. It is
possible not to fit sections of the roller with the PVC sleeve, e.g.
the free space for grooves. A minimum length of 50 mm is
required for a firm seating of the sleeve. With existing axial
forces, a greater minimum length must be selected.
When ordering a roller or RollerDrive with sleeve, always specify
the dimensions A to D.

24© 07 | 2023 Interroll

With the lower elasticity, the PU sleeve cannot be applied to any
other tube diameters or tubes with welded-on elements.
The PU sleeve is not glued onto the conveyor roller. The conveyor
roller is pushed into the sleeve widened with compressed air byusing a pressing machine. Then the sleeve is cut to the length of
the tube or to the specified dimension. Rollers with PU sleeve arealways designed with an antistatic element. The PU sleeve is notantistatic. Dusts can change the surface of the PU sleeve aftersome time, thereby reducing the coefficient of friction.

The PU sleeve ensures a high level of noise reduction, particularly
for steel containers, and offers a high level of protection ofsensitive conveying goods. An improved conveyance of
conveying goods is achieved with the higher coefficient of friction
compared with a steel tube. Conveying goods can easily beseparated since the larger diameter leads to a higher speed withthe same rotational speed. With mechanical stress, e.g. withabrasion, it offers a higher robustness than a PVC sleeve.

Lagging

Design versions
For tube diameters 40, 50, 51, 60, 80 and 89, a lagging of 2 to

The lagging ensures a high level of noise reduction and offers ahigh protection of medium-heavy to heavy conveying goods. An
improved conveyance of conveying goods is achieved with thehigher coefficient of friction compared with a steel tube.
Conveying goods can easily be separated since the larger
diameter leads to a higher speed with the same rotational speed.

The lagging is applied through hot vulcanization and reground.
This creates a high-strength joint of the lagging with the tube,
resulting in a surface that is highly resistant to abrasion and very
precise. For uncoated steel material, projecting tube sections areprotected against corrosion with a black paint coating. For
welded drive heads, the tube and drive head remain untreated.
Friction rollers (Series 3800, 3800 light, 3870) can be fitted onlywith 2-mm lagging.

GENERAL TECHNICAL INFORMATIONANTISTATIC ELEMENT

By default, the antistatic element is applied for all conveyor
rollers with integrated groove, all polymer-based drive heads,
tube sleeves, and tapered elements and can be selected as an
option for the following roller series:

Series 1700 heavy
Series 3500
Series 3500KXO light
Series 3500KXO
Series 3950

The antistatic element is available for the following roller
diameters:

The antistatic element creates a permanent electrical connection
between the metal tube and the shaft of the roller. If the side
profile is grounded accordingly and an electrical connection isestablished between the shaft of the roller and the side profile, nostatic charge is created on the metal tube surface.
The antistatic element can be applied for the following tube
materials or tube finishings:

Interroll recommends to ensure the electrical connection of theroller shaft to the side profile and to check the grounding
potential on the roller surface before and after the use of theroller. Threaded shafts are best suited to establish a reliable
electrical connection.

Steel conveyor roller

Application area
Driven unit handling conveying,such as transport of cardboards,
containers, barrels or tires. Suitablefor implementing gravity or push
conveyors. The roller is designed
for use in a very broad
temperature range from −28 to+80 °C. The version with steel
bearing housing is designed for use
in deep freeze applications orapplications with very high ambient
temperature.

38

High reliability
The solid steel roller distinguishes itself with distinct longevity and high resilience, thanks topressed and zinc-plated bearing shells with hardened running grooves.
Lateral loading
The tube ends are rounded, thereby allowing materials to be easily moved on from the side.
Axial forces are removed through ball bearings and seals.
Particularly robust
The shape of the ball bearings used is optimized for use in conveyor rollers so that large bearing
deflections are possible.

Steel conveyor roller

Dimensions
The dimensions of the conveyor roller depend on the shaft version. A sufficient axial play is already taken into account, so that only
the actual lane width between side profiles is required for ordering.
Ordering dimensions for tube sleeves, e.g. PVC sleeves, see page 24, and for flanges see page 27.

ROLLERSSERIES 1450
Heavy-duty universal conveyor roller

Application area
Driven and particularly non-driven
conveying systems, such astransport of cardboards,
containers, barrels, wheels, pallets
or steel containers. Thanks to acarrying capacity of up to
5,000 N, the product can be used
as universal conveyor roller forvery high loads. The roller series
can also be used for the
implementation of gravity roller
conveyors. The version with steel
bearing housing is designed for use
in deep freeze applications orapplications with very high ambient
temperature.

44

Low-noise
The use of precision ball bearings, Technopolymer bearing housings and seals result in very quiet
running.
Lateral loading
The tube ends are rounded, thereby allowing materials to be easily moved on from the side.
Axial loading capacity
Forces acting in axial direction are removed through ball bearings and seals.
Robust construction
To obtain an axial fixing of bearing housing, ball bearing and seal against escaping, the bearing
housing is not only pressed into the tube, but also flanged.

ROLLERSSERIES 1500/1520
Slide bearing conveyor roller

Application area
Non-driven container conveyor
systems where the roller isgenerally used for conveying
packaged or unpackaged foodproducts. Since high levels of
cleanliness requirements are met,
the roller can be used in moist
areas and a wet cleaning can be
performed.

Long service life
Smooth-running, wear-resistant slide bearings, which do not allow any grease to be washed out,
are installed in series 1500. In addition, the use of shaft pins made of stainless steel ensures ahigh corrosion resistance. Pressed-in bearing housings prevent foreign bodies from penetrating
into the inside of the roller.
Easy cleaning
Contaminations can be removed with commercial cleaning agents. For particular thoroughcleaning, the roller can easily be removed and reinstalled.
Simple installation
Slide bearing bushings allow engaging in a side profile with a maximum wall thickness of 2.5 mm
and hexagon holes (does not apply to series 1520).
Robust construction
For axial fixation of the bearing housing, the bearing assemblies for PVC tubes are secured withan internal press-in edge in addition to the press fit.

Removal of a roller of series 1500
A roller of series 1500 can easily be installed in hexagon holes using the supplied slide bearing bushings. If the roller must be removed
again, e.g. for cleaning, it is just as easy. Interroll recommends a 12-mm open-end wrench for the removal. The open-end wrench must
be placed between the inside of the side profile and the bearing housing of the roller. It must be placed on the hexagon so that thetwo bracket joints of the slide bearing bushing no longer project. The bracket joints prevent the slide bearing bushings frominadvertently dropping out of the side profile. If the bracket joints are placed by the open-end wrench, the slide bearing bushing caneasily be pulled out to the outside.

Small roller pitches
Small roller pitches can be implemented by using rollers with a diameter of 20 or 30 mm.
Robust construction
To achieve a high axial load capacity, particularly of bearing housings, ball bearings and seal,
the bearing housing is not only pressed into the tube for the versions with metal tube, but also
flanged. The bearing assemblies of the PVC tubes with a diameter of 30 mm are secured not
only with a press fit, but also with an internal press-in edge.

ROLLERSSERIES 1700
Universal conveyor roller

Application area
Driven and non-driven conveying
systems, such as transport ofcardboards, containers, barrels, or
wheels. Suitable for implementing
gravity or push conveyors. Also
usable as belt bearing roller (nodeflection).

Highest reliability
This roller series has been proven millions of times. The roller offers a very high degree offunctional dependability.
Low-noise
The use of precision ball bearings, Technopolymer bearing housings and seals result in very quiet
running.
Good protection against dirt and water
The roller excels with a good protection against coarse dirt and dripping water. An integrated
groove ensures that water can be rejected.
Lateral loading
The tube ends are rounded, thereby allowing materials to be easily moved on from the side.
Axial forces are removed through ball bearings and seals.
Extremely soft starting
If an oiled precision ball bearing is used, the roller will start particularly easily.
Robust construction
To achieve a high axial load capacity, particularly of bearing housings, ball bearings and seal,
the bearing housing is not only pressed into the tube for the versions with metal tube, but also
flanged. The bearing assemblies of the PVC tubes are secured not only with a press fit, but alsowith an internal press-in edge.

Dimensions
The dimensions of the conveyor roller depend on the shaft version. A sufficient axial play is already taken into account, so that only
the actual lane width between side profiles is required for ordering.
Ordering dimensions for tube sleeves, e.g. PVC sleeves, see page 24, and for flanges see page 27.

Application area
Driven unit handling conveying in
the curve section, e.g. of
cardboards, containers or tires.
Suitable for implementing gravity
or driven roller curves. Tight curveradii are possible if tapered
elements with a conicity of 2.2° areused.

High reliability
This roller series has been proven millions of times. Contrary to conventional curve rollers, theelements are secured against shifting. This allows the roller to offer a very high degree offunctional dependability.
Low-noise
The use of precision ball bearings, Technopolymer bearing housings and seals result in very quiet
running.
Good protection against dirt and water
The roller excels with a good protection against coarse dirt and dripping water. An integrated
groove ensures that water can be rejected.
Good running properties
The tapered elements made of polypropylene distinguish themselves with a low net weight sothat good startup properties can be achieved.
Robust construction
Robust tapered elements are abrasion-proof, noise-reducing, impact-resistant and excel througha high weather-resistance.

ROLLERSSERIES 3500
Fixed drive conveyor roller

Application area
Driven unit handling conveying,such as transport of cardboards,
containers, barrels or tires.

Low-noise
The use of polyamide drive heads results in very quiet running.
Lateral loading
The tube ends are rounded, thereby allowing materials to be easily moved on from the side.
Axial forces are removed through ball bearings and seals.
Robust construction
An axial fixation of the bearing assembly (bearing housing, ball bearing, seal) on the non-driveside can be accomplished in several ways. For the design with steel tube, the bearing assembly ispressed into the tube and then flanged. For the design with PVC tube, it is fitted with a groove
inside the tube in which the press-in edge of the bearing housing engages. For the designs with
PolyVee and round belt, the drive bearing assembly is also pressed into the tube and thenflanged.
Modular construction
With a permanently installed bearing housing for a tube diameter of 50 and 60 mm, insertablepolyamide drive heads, such as sprocket, toothed belt and flat belt heads, are interchangeable
and can also be exchanged with friction heads. Numerous drive versions are available with flat,
PolyVee, round or toothed belts as well as chains.
· Round belt drive headWith the round belt drive head, the drive section is separated from the conveying section, sothat conveying goods cannot be shifted due to batching belts. Since the drive head has ahigher friction because of grooves in the metal tube, the result is a higher conveyance of theround belts. If the round belts should slip because of the application, then the wear of the belts
on a round belt drive head is higher.
· PolyVee drive head
The nine grooves of the drive head allow the use of 2-rib, 3-rib or 4-rib PolyVee belts.
Compared with a round belt, the use of a 2-rib belt allows transferring approximately twice
the torque.

Application area
Driven unit handling conveying,such as transport of small
cardboards or containers. Suitablefor implementing driven roller
curves in the packaging industry
and for assembly machines as well
as for implementing machine
chains.

Good starting properties
Since the tapered elements are mode of polypropylene, the net weight is low.
Tight curve radii
Using elements with a conicity of 1.8° allows implementing curve radii of only 357 mm.
Robust construction
Robust tapered elements are abrasion-proof, noise-reducing, impact-resistant and excel througha high weather-resistance.
Additional components in the scope of delivery
The rollers are delivered with four taper disks and two ball sockets so that an angle
compensation can be created during fastening.

ROLLERSSERIES 3500KXOFixed drive curve roller

Application area
Driven unit handling conveying in
the curve section, e.g. of
cardboards, containers or tires.
Suitable for implementing gravity
or driven roller curves. Tight curveradii are possible if tapered
elements with a conicity of 2.2° areused.

High reliability
This roller series has been proven millions of times. Contrary to conventional curve rollers, theelements are secured against shifting. This allows the roller to offer a very high degree offunctional dependability.
Low-noise
The use of polyamide drive heads results in very quiet running.
Good running properties
The tapered elements made of polypropylene distinguish themselves with a low net weight sothat good startup properties can be achieved.
Robust construction
Robust tapered elements are abrasion-proof, noise-reducing, impact-resistant and excel througha high weather-resistance.
Variants
Depending on the requirement, the curve rollers can be supplied with drive heads for PolyVeebelts, round belts or chains.
· Round belt drive headWith the round belt head, the drive section is separated from the conveying section, so thatconveying goods cannot be shifted due to batching belts. Since the drive head has a higher
friction because of grooves in the metal tube, the result is a higher conveyance of the roundbelts. If the round belts should slip because of the application, then the wear of the belts on around belt drive head is higher.
· PolyVee drive head
Compared with a round belt, the use of a 2-rib belt allows transferring approximately twice
the torque. Conveying and drive technology are physically separated. A groove must remain
clear between two belts so that the belts cannot touch.

ROLLERSSERIES 3500 HEAVY
Fixed drive conveyor roller

Application area
Particularly suited for driven
transport of heavy materials that
require a small roller pitch, such as
pallets and steel containers.

Very robust design
Welded steel sprockets and steel tube with a dimension of 60 x 3 mm enable reaching a highmechanical stability of the conveyor roller. To achieve a high axial load capacity, the bearing
housing opposite of the drive side is not only pressed into the tube, but also flanged.
High load capacity
A stable, continuous female threaded shaft with Ø 17 mm ensures a high degree ofreinforcement of the conveyor. Reinforced precision ball bearings of type 6003 are used. A
corresponding small roller pitch is possible for the transport of very heavy goods.
High corrosion protection
After the welding process, the components consisting of tube, sprockets and flanges areindividually zinc-plated, thereby achieving a high corrosion protection.
Lateral loading
The tube ends opposite the drive side are rounded, thereby allowing materials to be easily
moved on from the side. Axial forces are removed through ball bearings and seals.

Double friction conveyor roller

Application area
Transporting and accumulating unit
handling, such as cardboards orcontainers. Also suitable for
implementing buffer sections.

Two-sided friction coupling
It is a double friction roller whose two-side friction couplings are connected with each other by
an internal tube. Positioning materials of different widths to the friction side are not required inthis case.
Robust construction
The drive heads are pressed together with the internal tube which secures them against
dropping out.
Numerous drive variants
A toothed belt drive head and sprockets with different number of teeth are available so thatwrapping and tangential chain drive can be implemented.
Note: Please read the additional important information about the use of the friction roller in theplanning section, Friction rollers.

ROLLERSSERIES MSC 50
Magnetic speed controller

Application area
Perfectly suited for use in gravity
conveyors, in end points at sorters
and spiral conveyors.

Purely mechanical solution
The purely mechanical solution renders a cabling or control redundant.
Maintenance and wear-free brake function
The contact-free eddy current brake operates maintenance and wear-free. It features the samehigh service life like a standard conveyor roller.
Soft startup
The gearless construction enables a softer startup which is already suitable for materials startingat 500 grams.
High braking power
Materials up to 35 kg can be decelerated. The tube diameter of 51 mm provides the necessary
higher surface to rollers with a 50-mm tube diameter given the same fastening height and allows
optimal braking.
Easy installation
The fastening holes of the conveyor rollers can be used so that no fastening holders withadditional profile holes have to be used. The direction-independent function rules out assembly
errors.
No impact on sensitive materials
No emissions to the outside are being generated, such as magnetism, which allows conveying
even sensitive materials, such as electronic components.
Conveyance with ease of smooth containers
The design with PU sleeve also decelerates critical materials in a reliable way.

PLANNING BASICS
CONVEYING GOOD

Conveying good
This chapter is intended to provide support in the planning of
conveyor systems and the selection of matching products.
The properties of the conveying good, the requirements withregards the conveyor system and the ambient conditions are thebasis for the planning of the system.

Length and width of conveying good

· Minimize the roller pitch as much as possible to ensure that the
products are conveyed smoothly with as large a base surface
as possible.
· Avoid rapid acceleration and harsh braking. Use MultiControl
as far as possible for controlling EC5000. These control systems
allow for purposeful matching of acceleration and decelerationof the RollerDrive.
· With inclined conveyor tracks, determine the center of gravityof the conveying good and check whether there is a risk of it
tipping.

The length and width of the conveying good have an effect onseveral factors:

Weight and weight distribution of the conveying
goodStraight running: The higher the ratio of length to width, themore stable will be the straight running of your items. With
smaller length to width ratios, it may be necessary to put in place
additional measures to stabilize the straight running of theconveying goods.

The weight of the conveying good must be distributed on anumber of conveyor rollers so that the maximum load capacity of
the individual conveyor roller and RollerDrive is not exceeded.
This may mean that more than three conveyor rollers must
support the conveying good.

Reference length: As a rule, the reference length corresponds tothe conveyor width +50 mm or for large conveying goods, suchas pallets, +100 mm. In curves, Interroll recommends the use oftapered conveyor rollers and RollerDrive whose length must be
calculated separately (see page 190).

In principle the weight of the conveying good should be
distributed as evenly as possible. The more uneven the weight
distribution is, the more difficult a reliable conveyance is.

Roller pitch: To transport the conveying good without problems,
the roller pitch must be selected so that the conveying good is
carried by three conveyor rollers at any given time.
Surface pressure: The different Interroll Conveyor Rollers andRollerDrive can be loaded with different forces. The static load
capacity can be taken from the respective chapter. The values
are based on the assumption that a conveying good rests on thecomplete usable tube length and not just on a part of it. If aconveying good has contact with less than approx. 50 % of theusable tube length, please have the application checked byInterroll beforehand.
Very long conveying goods generally do not rest on all conveyor
rollers and RollerDrive that are located under them. If, forexample, 20 conveyor rollers are under a piece of conveying
good, but the conveying good contacts only 15 conveyor rollers,then the load capacity of a roller must be greater than onefifteenth of the conveying good weight. For very long conveying
goods, the tolerance of the roller fastening height for conveyor
rollers and RollerDrive should be kept as low as possible so thatas many conveyor rollers as possible can carry the conveying
good.

Height of conveying good
The greater the height of the conveying good in relation to its
bottom area, the higher is the risk of it tipping over whentraveling on the conveyor. The following must be taken into
consideration:

180

If the weight of the goods is mostly at the front, then it is very
likely that the rollers at the end of the load carrier support only
very little weight. In the worst case scenario, the rollers at thestart of the load carrier could be overloaded.
The load capacity increases with larger tube diameter. For heavy
conveying goods, RollerDrive with a diameter of 60 mm should
be used instead. The load capacity is increased by rollers withthreaded shafts. In addition, the shafts reinforce the conveyor
and act as a cross tie.
Drive elements, such as round belts or toothed belts, must also be
selected while taking the conveying good weight into
consideration. Interroll recommends PolyVee belts for conveying
containers and cardboard cartons. Their service life and torquetransmission is significantly higher compared to round belts.

Material of conveying good
The material, and especially the condition of the base, has aneffect on the rolling and starting resistance.
Hard materials, such as polymer containers, feature lower rollingand starting resistances than soft materials, such as cardboard
cartons. This has a direct impact on the required drive output andmust be included in its calculation. The softer the underside of theconveying good, the higher is the drive output required for a
product with the same weight but with a hard underside. In
principle, the softer the conveying good, the smaller the roller
pitch needs to be.

The topic of environmental conditions is discussed below.

Static charging
In principle, conveyance via rollers creates electrostatic charging
which, among other things, depends on the properties of theconveying good and the tube material.
To prevent electrostatic charging from occurring or dissipate it
immediately and without creating sparks, Interroll offers antistatic
versions for rollers with steel tube. RollerDrive feature anantistatic design in principle. Sleeves, lagging and gray tapered
elements do not feature an antistatic design. For this reason,
Interroll recommends the use of black tapered elements forcurves.
Antistatic conveyor rollers and RollerDrive require the proper
manufacturing and check of the conducting connection between
shaft and side profile and the grounding of the side profile by thesystem manufacturer.

Noise is created by different components of a conveyor and theconveying good itself.

Rollers | Conveying elements | Accessories

When checking whether a roller has sufficient load capacity for
an application, it is important to take the condition of theconveying good into consideration. Conveying goods with anuneven bottom generally do not rest on all rollers that arelocated under them. With pallets, it must be ensured that only therollers under the bulk of the pallet are actually bearing the load.
The following diagram shows which runner load distribution
occurs for an evenly loaded euro-pallet.

Maximum throughput per time unit
Geometry of conveying good
Weight and weight distribution of the conveying goodControl requirements
Environmental conditions

Every drive creates noise. The RollerDrive is designed withdecoupling elements which reduce the noise of the gear box. In
most cases, the noise level of the RollerDrive is below 50 dBA.
More and more zero-pressure accumulation conveyor systems
are converted from pneumatic solutions with a centrally arranged
drive to a RollerDrive solution. The significantly lower noise levelis a deciding factor here.
The following applies to the noises of drive elements: A chain
drive causes more noise than a belt drive. At high accelerations
and decelerations, slipping round belts can cause squealing
noises. Interroll recommends reducing the acceleration anddeceleration of RollerDrive or using PolyVee belts. In this case, therisk of squealing noises is greatly minimized.
Very quiet rollers, RollerDrive and drive elements are of little use
if the conveying good on the conveyor creates noise. Various
measures can counteract it. The following should be observed inthis case:

181

Planning basics

Ribs, keyways, strips or grooves in the bottom of conveying goods
that run parallel to the direction of conveyance, do not pose a
problem concerning transportability. The required drive output
increases depending on their shape. Cross ribs can negatively
impact the transporting. It may be necessary to determine theroller pitch empirically.

·
·

PLANNING BASICS
DRIVE CONCEPTS· A small roller pitch generally causes less noise than a large
roller pitch.
· Keep height tolerances at transitions from conveyors and at thefastening of rollers/RollerDrive as small as possible.
· Fitting the rollers/RollerDrive with noise-reducing materials, e.g.
with a PVC or PU sleeve· Use of noise reduction inside of rollers for rollers with adiameter of 50 mm.

Humidity
Humidity can occur in different forms as a result of the following:· moist conveying goods, e.g. bottle crates stored in the rain
· moist environment, e.g. sculleries· applications that become moist, e.g. because of cleaning or
tripped sprinkler systems
If humidity can be expected in a system, then all components
should be checked for corresponding resistance.
Interroll offers a series of products that are suitable forapplications with humidity, water exposure, or water jets:
Tube material: Rollers and RollerDrive can be manufactured
from rust-free material, such as stainless steel. In addition,materials can be protected with different finishing processes, suchas zinc-plating.
Shaft material: Shafts for conveyor rollers can be manufactured
from rust-free material, such as stainless steel.
Drives: The RollerDrive already has a high degree of protection
with protection rating of IP54. If water jets can be expected in theapplication, Interroll recommends the design with protection
rating IP66.
Bearing: All rollers with precision ball bearings are well
protected against moisture and dust. For systems with constanthumidity or moisture, Interroll offers designs with stainless steel
ball bearings.

Applications in deep freeze area
Applications with an ambient temperature of approx. –28 °C are
particularly prevalent in the food processing sector. Many items
must be taken into account in the so-called deep freeze area:· Changed starting torque of conveyor rollers and drives.
· Increased viscosity of greases, e.g. in ball bearings or gearboxes.
· Possibly frozen and, therefore, less flexible components, such as
drive elements.
· Functional safety of all components through different
contraction of various materials.

182

The solutions from Interroll
Materials: For various products, Interroll offers variants that are
particularly suited for deep freeze applications. The tapered
elements for conveyor rollers and RollerDrive are manufactured
impact-resistant. Conventional materials used are often brittle
and break easily. The bearing housings of series 1700 are
designed as high impact-resistant for deep freeze applications.
Drive elements: Before using a drive element, its suitability fordeep freeze applications should be checked. It should also beensured that the friction at temperatures below zero is sufficientand the drive elements cannot freeze since frozen drive elements
could pose unplanned torque requirements for the drive. The
PolyVee belts offered by Interroll are suitable for deep freeze
application (see page 178).
Bearing: The precision ball bearings used also work in deep
freeze conditions. However, the startup of the roller is higher inthis case than at an ambient temperature of 20 °C. RollerDriveare either designed for this higher startup, or oiled ball bearings
are being used. The oiled bearings run significantly smoother attemperatures below zero.
Under deep freeze conditions, materials such as steel andpolymer contract in different ways. For functional reliability, a
PolyVee drive head for a RollerDrive is not only pressed into thesteel tube, but it is also flanged. Additional security is provided bya metal star. This star, which is being produced with laser cutting,is engaged in the drive head and channels itself into the insidewall of the tube. This innovative solution inside the tube allows
avoiding interfering edges on the outside contour of the tube.
This solution is available as an option for various designs series
3500 and 3500KXO.

Drive concepts
With respect to drives, Interroll distinguishes between drives (suchas round belts, PolyVee belts, chains, etc.) and the actual drive.
Different drives are used in conveyor systems, such as drum
motors, gear motors, motor rollers, etc. Furthermore, the potential
energy of conveying good, e.g. on gravity conveyors, is also
being utilized.

Gravity conveyors
A gravity conveyor differs significantly from the other concepts. It
is not horizontally aligned, but always mounted at an incline.
There are driven and non-driven gravity conveyors. Driven
gravity conveyors can transport conveying goods upwards anddownwards. These conveyors can be driven with RollerDrive. If
the RollerDrive and, as such, the conveyor is stopped, theconveying goods remain in place and do not slide downward.
The EC5000 holds its position with a certain torque which
prevents any downward sliding. The different gear boxes andpowers offer different zero motion holds. It must be ensured that© 07 | 2023 Interroll

· The incline of the conveyor· The already existing speed of a conveying good when placed
upon the gravity conveyor· The ease of movement of the rollers· The conveyor length· The condition of the underside of a conveying good
· The weight of the conveying good
· Other properties
On the one hand, the conveying good must reach the end of theconveyor. It must not stop because its weight is too low to startmoving rollers at rest. If many conveying goods are already on a
gravity conveyor and, as a result, a piece of conveying goodstops in the last section of the conveyor, then it must be ensured
that the last item will start again and reach the end of the gravity
conveyor after the first conveying goods have been conveyed.
On the other hand, the speed of the conveying goods must not
be or get too high. There is the risk that a conveying good hits
another jammed conveying good or the end stop at the end of
the conveyor. This creates an injury risk for employees who may
want to remove the conveying good by hand, as well as the riskof damaging the conveying good.
Establishing the matching properties of a gravity conveyor
becomes a challenge if different conveying goods have to be
moved. Generally, the conveying goods on a gravity conveyor
differ by at least one of the following properties: Weight, size,
material and base condition. A mixture of different conveying
goods can also be transported by a gravity conveyor withrespect to personnel and conveying good safety as well asprocess reliability. Interroll offers different products for thispurpose. The rollers of series 1100 are designed for use ingravity conveyors.
The magnetic speed controller MSC 50 enables the restart ofconveying goods starting at 0.5 kg and reliably decelerates
conveying goods up to 35 kg depending on the properties of theconveyor. If conveying goods are lighter than 0.5 kg or heavier
than 35 kg, it is also possible to use the RollerDrive series
EC5000.

© 07 | 2023 Interroll

In principle, it is recommended to test every gravity conveyor
design under original conditions.
If drives are used in gravity conveyors, it must be ensured thatthey hold the conveying goods at standstill. But this is possible
only if the drives are supplied with voltage. If the system voltage
fails, all conveying goods will move downwards. This can beprevented with the Stop Roller that is designed for thisapplication case. It is also connected to the system voltage andstops the conveying goods as soon as the voltage is lost. It is
recommended to connect the Stop Roller, RollerDrive and rollers
used via PolyVee belt. Due to dynamic braking torques, 3-rib or
4-rib PolyVee belts should be used.

Fixed drive conveyor
If a conveying good moves in harmony with the drive, then it isgenerally a fixed or constantly driven conveyor. The drive headof the rollers used is permanently connected with the tube. If the
fixed drive heads are replaced with friction drive heads, theycreate a friction conveyor. Many different types of fixed drive
conveyors are possible. They generally differ with respect to theselected drive element, such as chains, PolyVee belts, round belts,
etc., and the drives used.
For all current fixed drive conveyors, Interroll offers matching

and PolyVee belt even drives and drive elements. When using aRollerDrive as drive, it is recommended to place it in the middle ofthe driven conveyor rollers (for information about the Pallet
Drive, see the separate product documents). If many rollers haveto be driven, then PolyVee belts offer advantages over roundbelts. The use of PolyVee belts reduces the number of roller
revolutions with increasing distance to the RollerDrive.

Rollers | Conveying elements | Accessories

The conveying good rolls without additional drive as a result of
the potential energy up to the end of the conveyor or up to thepreceding conveying good. The speed and the restart capabilityof conveying goods is heavily influenced by:

The driven RollerDrive ensures that every lightweight conveying
good, regardless of its weight, can be moved or moved again.
When decelerating heavy conveying goods, the energy
recovered by the RollerDrive must not be too high. If one orseveral RollerDrive are used within a gravity conveyor, it also
provides the advantage of accumulation pressure reduction. If a
RollerDrive, which may be connected with additional rollers via
drive elements, is stopped, then the conveying goods stop. This
allows reducing the pressure on conveying goods that are
already on the conveyor or on the stop at the end of theconveyor. On long gravity conveyors, it may be advisable to use
several RollerDrive in order to reduce the accumulation pressure
even further. If the incline is so high that conveying goods slide
over the steel tube of a stopped RollerDrive, rollers or Stop
Roller, then the friction may be increased with a PVC or PU sleeveon the tube.

Planning basics

conveying goods do not slide over standing rollers; if necessary,
friction must be increased, e.g. with the use of PVC or PU sleeveon rollers, RollerDrive and Stop Roller. Gravity conveyors use thepotential energy of conveying goods. This means that othertechnology must first move the conveying good to acorresponding spatial height.

PLANNING BASICS
DRIVE ELEMENTS

Friction conveyor
Friction conveyors are generally used to transport andaccumulate materials. The special thing about friction conveyors isthat an accumulation of materials can be accomplished with only
little accumulation pressure when the drive is switched on. The
same situation on a fixed drive conveyor would cause thematerials that were stopped first to receive so much pressure
from the subsequent materials that fragile cardboards could bedamaged. Friction conveyors are well suited for buffer sections
with non-uniform loading and unloading.
Friction conveyor rollers are available with many different drive
elements, see page 187. Even a conveyor with drive shaft can beused as friction conveyor. The guide wheel of series 2600 enables
not only guiding a round belt, but it also enables the drive shaft
to turn while the wheel remains at rest. It must be ensured thatthe round belt does not slip through as this could significantly
shorten its service lie. For additional information, see page 187.
For some application's, it is a disadvantage if the materials touch,even if the accumulation pressure is reduced by the friction
operation. In this case, a conveyor working at zero pressure
accumulation may be better suited – see the next chapter (foradditional information about friction conveyors, see page 187).

Zero pressure accumulation conveyor
The zero pressure accumulation conveying is often abbreviatedas ZPA. A ZPA conveyor is generally divided into zones. The zone
length is based on the length of the conveying good or the
longest conveying good. Each zone features an option ofidentifying conveying goods, e.g. via a photo cell. In addition,
every zone can be switched on and off. The zones are driven indifferent ways, see the examples below.
One option consists of a central drive, often a gear motor, thatdrives a flat belt. The flat belt is pressed onto the rollers using aswitchable unit or guided past them. In the case of bypassing, therollers are also often decelerated. It is feasible that the flat belt ispressed onto only a few rollers of a zone and the remaining
rollers are connected with them by means of other drive
elements. In many cases, this switching unit consists of pneumatic
valves. They frequently cause an undesired noise level. A highlevel of energy can be expected for this ZPA solution since thepowerful gear motor must also be powered if, for example, only
one conveying good has to be moved on a 40-zone section.
Another option always presses the flat belt against a section of aroller in every zone. The remaining portion of the roller isswitched in or out via a coupling. The remaining rollers of every
zone are connected with the driven roller via other drive
elements.

184

Another concept is the use of decentral drives. Motor rollers areoften used for this purpose. In this case, drives which are directly
driving the respective rollers, are installed in one or several
rollers of a zone. A drive element connecting the entire conveyor
is redundant. The remaining rollers of a zone are generally
connected with the motor roller(s) using PolyVee or round belts.
The zones can be activated or deactivated by purposefully
switching the motor rollers on or off.
Depending on the length of the conveyor, the design with central
drive usually falls below the investment costs of a solution withmotor rollers. However, the operating costs tend to be higher due
to the constant turning of the drive, even when nothing may be
conveyed at the time. For most solutions with motor rollers, higher
investment costs are possibly amortized after a short time.
Not only the lower energy consumption speaks in favor of asolution with motor rollers, but also the compact design. The
motor is installed in a roller and does not have to be placed next
to or below the conveyor.
Compared to gear motors, motor rollers are maintenance-free,they do not have to be greased and generally offer a higher
safety level with a protected extra-low voltage.
But solutions with motor rollers can also have disadvantages. For
solutions with many motor rollers per zone, the availability
decreases – the more motors are being used, the higher the
probability that a motor roller fails.
For this reason, Interroll recommends the use of the RollerDrive
EC5000. In this case, one RollerDrive per zone is generally
sufficient, and flexible control concepts are available.
Furthermore, the controls offer many other options, such aschange of direction of rotation or start and stop ramps which are
not being offered by conventional ZPA conveyors.

Drive elements
With respect to drives, Interroll distinguishes between the actual
drive, such as RollerDrive, drum motor, Pallet Drive, gear motor,
etc. and the drive elements. Drive elements refers to different
types of the torque transmission. Only the following drive
elements are considered in this chapter:· Toothed belt
· PolyVee belt
· Round belt

Chains
The chain is a tried and trusted method for driving conveyor
rollers and conveyor elements in conveyor systems. Chains arecharacterized by their robustness and durability and are not© 07 | 2023 Interroll

Conveyor rollers with flanges welded on are often used for
guiding pallets. Guiding pallets via flanges increases the power
demand and must be taken into account during the dimensioningof the drive and drive elements.
The maximum drive length to be moved by a drive is limited by
the permissible load of the chain. The following factors determine
the maximum drive length "L":· The permissible tensile load of the chain FMAX in N
· The gravitational force of the individual material to betransported FT in N
· The roller resistance µ of the conveyor track, whereby a valueof 0.1 is generally selected· The projected conveying speed "S" in m/s· The placement cycle "t" of the materials (in S), i.e. the time
between two successive pieces of material to be conveyed
The maximum drive length "L" is being calculated:

L=

Fmax · S · t
Ft · μIf the drive station is positioned in the middle of the conveyor forthe drive from roller to roller, then twice the drive length cantheoretically be implemented. The sprockets that transfer thedrive output must not be overloaded in such a case.
Based on the overall efficiency of this system, long drive lengths
should be avoided. In many cases, drive lengths of more than 15
m have proven to be problematic.
FMAX can be determined with the permissible breaking load FB ofthe chain used. A safety factor of 7 (for which the wear of thechain is also within an acceptable range) is generally used for thispurpose so that FMAX can be determined as follows:

Fmax =

The tangential chain drive is characterized by its good level of
efficiency and simple design. The drive head (2) consists only of
one sprocket. For this reason, the installation length of theconveyor roller is shorter for a roller-to-roller drive. A single
chain (1) drives all of the rollers in a conveyor. The chain is
guided to the sprockets by a chain guide profile. The chain guide
profile (5) is usually made of special plastic and must guide thechain extremely precisely.
When used in fixed drive conveyors, the sprockets arepermanently connected with the tube of the conveyors. Friction
conveyors use rollers whose sprockets are not permanently
connected with the outside tube. 1 to 2 teeth of the sprockets
mesh into the chain and only transfer the driving power required
for the individual roller. The chain can be guided either along the
top of bottom of the conveyor rollers. The precise positioning of
the chain guide in relation to the conveyor rollers is extremely
important. The maximum play in terms of height is 0.5 mm. The
central motor station (4) must be installed in such a way that thedriving side of the chain is as short as possible. It is advisable toprovide the motor station with additional equipment for adjusting
the chain tension. Idler pulleys (3, 6) guide the chain at the drive
and/or end of conveyor in the corresponding direction. It is also
possible to use the last conveyor rollers as chain deflection. In thiscase, it must be ensured that these rollers feature a DIN gearing.

185

Rollers | Conveying elements | Accessories

Chains are not maintenance-free and are relatively loud inoperation. They must be lubricated regularly in order to achieve
an optimum service life. The noise created by a chain as drive
element increases with increasing speed. For this reason, speeds
higher than 0.5 m/s are not recommended.

sensitive to dirt and environmental influences. Very high levels of

Idler pulleys, which have to carry not only the load of thematerial to be conveyed, but also the chain traction forces, must
be checked specifically with regard to their permissible bearing
load. The driven conveyor length is restricted by the permissible
breaking load of the chain and by the weight of the material tobe conveyed.
The roller spacing (roller pitch) can be selected as required with
tangential drives. Compared with roller-to-roller drives, theconveyor rollers are easy to fit and remove with tangential drives
since they are not wrapped by the chain.
Starting at 1,000 operating hours, a lengthening of the chain of
up to 2 % can be expected.
Wrapped force transmission

With wrapped force transmission, every conveyor roller isconnected to the next one by a chain (1). For this reason theconveyor rollers require double sprocket heads (2). They needmore space than with a tangential drive, so that the installation
length of the roller is longer. Double sprocket heads always
feature a DIN gearing (standard gearing).
An additional chain guide is not required. The roller pitch is
subject to very tight tolerances and depends on the chain pitch.

Toothed belt
The share of toothed belts as drive element in roller conveyor
systems is declining. Toothed belts are generally used from roller
to roller and are unable to negotiate curves. Compared to roundor PolyVee belts, the power requirement of a toothed belt issignificantly higher because of its design. This must be taken into
account in the selection of the drive. Toothed belts pose a highdemand on the tolerance of the roller pitch since the toothengagement is form-fit with the profile of the drive head. Interroll
recommends obtaining the tolerances to be followed from the
manufacturer of the selected toothed belt.
One advantage of the toothed belt compared to round and
PolyVee belts, is the fact that it passes movements withoutslipping when used properly. On top of that, toothed belts are
low-noise and maintenance-free, lubricating or retensioning is not
required.
The drive length of a conveyor with toothed belt drive should be
dimensioned so that the overall load of 12,000 N conveying
good being conveyed at the same time is not being exceeded.
For the roller series 3500 and the RollerDrive EC5000, a
maximum toothed belt width of 12 mm and a Poly-Chain GT
gearing is recommended.

PolyVee belts are ribbed V-belts that are generally used for thetorque transmission from roller to roller in roller conveyor
systems. The belts must feature a flexible tension member which
renders them significantly less flexible than most round belts.
Nevertheless, they can accept tolerances within the roller pitch
because of their flexibility and used as drive elements in curves.
For the installation of PolyVee belts, Interroll recommends the useof a PolyVee tensioning device, see page 179.
Compared to round belts, PolyVee belts can transfer a higher
torque of up to 300 %, the service life is longer and, when usedproperly, a PolyVee belt does not slip over the drive head. In© 07 | 2023 Interroll

In container conveyor systems, 2-rib and 3-rib PolyVee belts are
generally used. Interroll offers PolyVee belts for these designs forthe most common roller pitches, see page 178. The 9-rib drive
head also allows using 4-rib belts. The ability of high torquetransmission also carries with it a high demand on safety. Injuries,
such as jammed fingers between PolyVee belt and drive head,must be avoided. Interroll offers a finger guard for the mostcommon roller pitches. It does not have to be fastened to the side
profile and, for this reason, can be used for almost all side
profiles, see page 179.

Round belt
Round belts, also referred to as O-rings, are available in different
materials, colors and diameters. They are often used for thetorque transmission from roller to roller. Round belts are costeffective with respect to their purchase, are very flexible and canbe installed with ease. The disadvantage is a relatively poor
power transmission and relatively short service life. For thisreason, the use of PolyVee belts predominates in conveyor
systems.
The round belt guides with the RollerDrive EC5000 can be
carried out via grooves in the tube or a round belt drive head.
The drive head made from polyamide offers the advantage thatthe round belts can be guided closer at the end of the RollerDriveor at the side profile of the conveyor. In this case, it is more likely
to separate torque transmission and running surface of conveying
goods. Furthermore, the concentric precision is increased since nomechanical change of the tube occurs compared to grooves inthe tube.
The round belt drive head offers a higher conveyance for mostbelts because of its material. This significant advantage must be
taken into account if acceleration and deceleration for start-stop
operation are so high that the belt briefly slips and wears out
because of it. The better the conveyance from the guide, thehigher the wear in this case. Groove solutions in tubes and also
the round belt drive head offer 10 mm wide grooves. This allows
using round belts with a maximum diameter of 6 mm. In case ofhigher round belt diameters, there is the risk of two contact pointsof the round belt – at the bottom and at the side of the groove.
In this case, the belt is subjected to two different speeds andexperiences above average wear.

Flat belts are used for tangential force transmission. In this case,the flat belt is guided under the rollers and, in each case, pressedagainst a part of the roller. This can be the tube or a drive head.
Flat belts are used to construct fixed drive conveyors and friction
conveyors. It is also possible to drive zero-pressure accumulation
conveyors with flat belts. In such a case, the flat belt ispermanently driven. Stopping subsections is done by decoupling
the roller with the moving flat belt. Given the constantly turning
central drive, this type of zero-pressure accumulation conveying
leads to significantly higher energy consumption. Interroll
recommends the use of RollerDrive as an alternative.
Flat belts hardly ever need any maintenance. A precise guiding of
the belt is required. The flat belt is generally put in motion by agear motor can must be brought to a pretension of approx. 1 %with a tensioning device. The drive power is generally transmitted
more reliably if the loop angle of the flat belt on the roller can beincreased with narrowing wheels.
Interroll offers different products for the use of flat belts. The
conveyor rollers of series 1700 are frequently used for fixed
drive conveyors. The series 3500 as fixed drive head is available
with a flat belt drive head. The series 3800 offers friction
solutions for flat belts. And the series 2600 offers several
pressure rollers to guide and press on flat belts.

Friction rollers
Introduction
If materials are accumulated on a roller conveyor and the rollers
continue to be driven, it creates accumulation pressure. Thisaccumulation pressure continues to grow the more materials arebeing driven by rollers. As a result, it can damage the undersideof the material to be conveyed. In addition, it is possible that thefirst piece of material, which is generally stopped by a mechanicalstopper, will be squashed. Friction rollers prevent these problems
by reducing the accumulation pressure.
Friction rollers are based on the principle of the slip coupling. In
this case, the friction force in the coupling must overcome therolling friction between material and roller. Friction rollers offer
the option of setting up accumulation conveyors with minimal
accumulation pressure. When materials are stopped, the rollers
will also stop. The drive of the friction rollers continues to turn inthis case. When the stop is canceled, the complete roller units turnagain and move the materials. In this case, the conveyance isload-dependent.
The bearing housing of the series 3800 is designed as a greasedfor-life slip coupling and guarantees the roller's constantconveyor force. A tangential drive has proved itself to be
especially economical when used on friction conveyors. For this187

Due to the design of the PolyVee drive head and the small widthof the belts, they can be placed very close to the side profile. This
leads to an optimal tube utilization for conveying goods. With thesmall diameter of the PolyVee drive head, any contact of PolyVeebelt and conveying good is generally ruled out.

purpose, a central drive moves a long chain or a flat belt. The flat
belt or the chain are guided past the drive unit underneath theconveyor rollers so that all conveyor rollers are operating.

Application notes· Conveying goods– Even and stable bases of the conveying goods are ideal sothat each friction roller carries the material evenly. Soft,lightweight or uneven conveying goods, e.g. cardboards,
can be unsuitable for a friction conveyor.
– Only those conveying goods can be used that prevent a
mutual lifting out because of their shape. If necessary, thenumber of conveying goods to be accumulated must be
restricted.
– Round conveying goods are generally not suitable since
they distribute randomly on the conveyor during
accumulation. To prevent round conveying goods fromfalling off of the conveyor during accumulation, a suitableside guide is required.

· The conveyor force, which is produced by the friction roller bymeans of friction, regulates itself relative to the weight of theconveying good. The conveyor force is seriously affected by
the following factors:– Weight of conveying good
– Base condition of conveying good
– Position of conveying good
– Humidity– Temperature– Percentage of accumulation mode over the entire running
time
These factors have, to an extent, a considerable effect on theoperation and operational lifespan of the conveyor roller. The
task is to find out the sufficient conveyance for the respective
conveying good to be conveyed. A dimensioning test under
original conditions is generally required for this purpose.
· To enable starting up the conveyor even with complex
conveying goods, the following measures may be helpful:– Selection of the correct friction roller. An adjustable or a
double friction roller may be better suited.
– Reducing the roller pitch: With less load on each roller, itsconveyance ability is also reduced.
– Creating a contact pressure from the drive head onto thebearing housing in axial direction.
– Design of a minor incline in conveying direction· Duration of accumulation mode

– Accumulation mode should only be used for as long as isnecessary. When it can be seen that no conveyance willtake place, then the central drive should be switched off. No
energy will be used and the service life of the conveyor
system will be increased. An overtemperature of theabrading polymer elements must be avoided.
– For long accumulation mode, steel sprocket drives offer an
improved dissipation of the friction heat.
Placement of conveying good
– If the conveying good is significantly narrower than thefriction roller, it can affect the conveyance ability. With
single friction rollers, the conveyance decreases the further
away the conveying good is from the friction drive.
– The same applies to the center of gravity of a conveying
good. The closer the center of gravity is to the friction drive,the better the conveyance.
Friction roller– Flanges as well as other side guides cannot be used for
friction rollers. The friction that is being created could
possibly not be overcome by the conveyor force of thefriction coupling.
– The use of friction rollers represents a minimum requirementon the tolerance of the installation height of the rollers. If afriction roller that is installed at a low level is followed by aroller installed slightly higher, this may represent aninterfering edge to the conveying good that cannot be
overcome.
– When using tube sleeves (e.g. PVC sleeves), a maximum
sleeve material thickness of 2 mm is recommended.
The maximum permissible conveying speed is 0.5 m/s.
Use only under dry conditions
The bearing housings that are part of the friction element,
contain pockets. These pockets are filled with special grease.
The grease must not be removed! It allows better startup
values, due to the high adhesive force of the grease. In
addition, friction heat that is being created, is dissipated better
through the grease, and the wear of the polymer parts is
reduced.

If the material is stopped, the tube stops and the drive head turns
inside the bearing housing.

The product description of series 3800 light is located on

Series 3870
Series 3870 offers different polymer sprocket heads. A drive
head and a bearing assembly on the other side are pressed into
an internal tube. This unit is integrated into the external tube. The
operating principle corresponds to series 3800, whereby theinternal tube rotates in the two bearing housings of the external
tube. If a material to be conveyed is stopped, the drive headturns together with the internal tube, and the external tube isstanding still. The advantage of this solution is that both sides of
the roller feature a friction unit and conveyor force is generated
with an off-center load.

Series 3800 – adjustable
With the adjustable series 3800, a 1/2“ steel sprocket drive headwith 14 teeth is available, whereby the operating principle
corresponds to the one described above. In addition, a malethreaded shaft protrudes from the roller on the other side of thedrive head. There is a nut and a spring on the shaft. Tightening
the nut tensions the spring, which exerts an axial force from thedrive head onto the bearing housing. This axial force increases
the conveyance to up to 12 % of the roller load. The more thenut is tightened, the earlier the tube is turning.

How to build a curve?
It is possible to build roller curves with cylindrical rollers. With
such a design, materials to be conveyed are not conveyed in thecenter of the curve, but alongside a required side guide. Thisrequires more energy and it poses the risk of damage to the side
guide or material that is being conveyed. For this reason, thedesign with tapered conveyor rollers is recommended.
The diameter of the tapered rollers increases towards the
direction of the outside curve diameter. With the increasing
diameter, the circumferential speed increases. This allows
materials to be transported through the curve without losing theirorientation. With the usual speeds (max. 0.8 m/s) and ideal curve
design, a side guide is not required.
Interroll offers different curve-capable rollers that feature thedesignation KXO. These are rollers with cylindrical steel tube onto
which tapered elements are pushed. The following series are
suitable for use in roller curves.

189

Planning basics

Series 3800 offers different drive heads. A drive head is set inmotion using a drive element and turns inside the bearing
housing. The bearing housing applies force onto the drive headwith the weight of tube and material to be conveyed. This friction
force causes the conveyance of bearing housing and tube. The
material to be conveyed is moved through the rotation of the
tube.

Length of tapered elements
1.8° elements: The first tapered element has a length of 45 mm
or 95 mm. All additional elements have a length of 100 mm. The
total length of the tapered elements can be selected in incrementsof 50 mm. The different lengths of the first tapered elements
result in 2 different inside curve radii.
2.2° elements: The length of the first tapered is always 140 mm.
Hence, the inner curve radius does not vary.

Radii
Different inside curve radii can be created with the different
Interroll Curve Rollers. A material will be conveyed perfectly
through a curve only if the radii are being maintained.

Planning basics

Curve rollers of series 1700KXO and 3500KXO can be
manufactured with a tube projection. It is possible that the tube
projection is located on the side of the tapered element with thesmaller diameter. The first tapered element will then have thecorresponding distance to the curve side profile. With this design,
it must be taken into account that the inner curve radius must be
reduced with a tube projection of more than 20 mm. A tube
projection on the side of the tapered element with the larger
diameter does not have any effect on the inner curve radius.

The calculation of the roller pitch is performed at the outsideradius. With a roller-to-roller drive, the inside and outside
sprockets are used alternatingly. The roller pitch should be
dimensioned so that a chain on the outside sprockets is perfectly
tensioned. With the same roller pitch in the curve, the chain on
the inside sprockets will be tensioned a little bit less because of
the reduced distance of the sprockets to each other.
The roller pitches at the inside and outside radius must be
calculated on the basis of the chain pitch.

Inside curve radii for rollers with grooves
Grooves are applied within a tube projection at the inner curve
radius. The table "Inside curve radii for non-driven curves" lists
the curve radii for the rollers of series 1700KXO. The tube
projection must then be subtracted from the corresponding curve
radius.

For a conveying good to be conveyed perfectly through thecurve, the curve speed and the speed of the straight conveyor
line must be identical before and after the curve. The curve speed
refers to the average speed. If the speeds of straight and curve
are different, the conveying good can loose its orientation and,as a result, reach the side guide.

The following information on the number of conveyor rollers
required relates to a 90° curve on which a higher surface to the
90° angle of the side frame has been designed in forequalization.

Different forces occur in a curve. If the centrifugal force is greaterthan the static friction force, conveying goods will almost always
loose their orientation. This occurs at speeds over approx. 0.8 m/
s. At that point, conveying goods will no longer be conveyed
through the center of the curve and come into contact with theside guide at the outside radius. This depends on various factors,
such as material and condition of the underside of the conveying
good, and these factors should also be taken into account during
the planning of the curve.

Roller curves can also be operated in the deep freeze area. An
ideal drive is the RollerDrive EC5000 in deep freeze design.
Driven rollers should feature oiled ball bearings so that therequired drive power is not increased unnecessarily. Interroll
recommends PolyVee belts as drive element. They have to bewatched for suitability for deep freezing and that the belt tension
is not too high.

Tapered elements of conventional curve rollers carry the risk ofshifting on the tube. Interroll secures the tapered elements without
creating an interfering edge that is visible on the outside.

DIMENSIONING OF MAGNETIC SPEED CONTROLLER

Number of rollers

Dimensioning of magnetic speed
controller
The Magnetic Speed Controller MSC 50 is a mechanical speed
controller that ensures a controlled speed on gravity conveyors
with conveying goods weighing up to 35 kg.
In contrast with conventional products, the speed controller
operates without a gear box, thus enabling startup for very
lightweight containers starting at 0.5 kg. The maximum
mechanical output is 28 W, thus providing the required© 07 | 2023 Interroll

Planning basics

The calculation or determination of the roller pitch and the angleof the roller curve result in the number of rollers to be used,which is not always an even number. In this case, the value must
be rounded up or down.
If a PolyVee belt is used in the curve for a roller pitch of 73 mm(based on a straight conveyor line), it results in an even roller
count for the following curve angles:

consistently high braking power for heavy containers. The
operating principle is based on an eddy current brake. A double
shielding of the magnets enables a uniform braking action.
Conventional products often contain brake shoes. The heavier aconveying good, the stronger the braking of these brakeelements. This purely mechanical braking process causes wear. It
means that such products have to be replaced after a certain
time since the brake shoes are worn off. Such a wear does nottake place in the MSC 50.
The hexagon shaft used serves the torque within the side profile.
A loose, form-fit installation of the hexagon shaft is possible withhexagon holes in the side profiles. A hole size of 11.5 mm is
required for an oblique installation. With a fixed installation using
a female threaded shaft, a minimum torque of 20 Nm must be
applied. Interroll recommends the additional use of a screw
locking device.

Adjusted to the length of theconveying good

· With infeed speeds into the gravity conveyor greater than 1
m/s, Interroll recommends the installation of three to four MSC
50 at the beginning of the gravity conveyor. The placement on
the first 1,000 mm is used for immediate reduction of the
speed. On the rest of the gravity conveyor, the distance values
specified above can be applied as guide values.

The speed controller without PU sleeve is manufactured with atube diameter of 51 mm. Together with conveyor rollers of 50
mm diameter, a minimum higher surface of 0.5 mm is created.
This provides sufficient contact to the conveying good, whichleads to an optimal braking function.
The distribution, number and design of the speed controller in aconveyor track depends on many parameters:

·
·
·
·

Incline of conveyor trackRoller pitch
Infeed speed, e.g. by a sorter
Conveying good weight
Condition of the underside of the conveying good

The data listed below has been determined by means of
numerous tests. Conveying goods with optimal undersides wereused for this purpose. The data is intended to provide a reference
point for the dimensioning of applications, whereby the
combination of critical parameters is very large. Due to themultitude of influencing factors, Interroll cannot provide specificinformation about conveying speeds and, for this reason,recommends to empirically determine the final layout:· Lightweight conveying goods can run very slowly (approx.
0.01 m/s).
· Under optimal conditions, heavy conveying goods can run at
0.5 m/s.
· The design with PU sleeve is intended to improve the static
friction for smooth plastic containers. The PU sleeve isparticularly recommended in combination of conveyor tracks
with large inline and high conveying good weights.
· For cardboard boxes and many other conveying goods, thefriction in combination with a zinc-plated steel tube is sufficient.
· Inclines from 5 % to 10 % were examined in numerous tests.

Controllers were tested successfully:
