4) Adequate lubrication quantity isalso essential for a chain's longer
service life.

● Usually 4~20 drops of oil per
minute.
● Excess oil should be reserved ina simple case.
● Effective at medium and low
speeds.
● To be dipped 6~12mm.

OIL LEVEL

It also reduces noises and cools
down the chain running at highspeed.

3) Avoid mix of oil with anotherkind or other maker's.

● Periodically to keep chain joints
from drying.

BRUSH

Abrasion between the pin andbushing causes roller chains tostretch. Therefore, these parts should
be well lubricated.

The oil forms a film which
minimizes wear of the pin andbushing thus increasing the chain
service life.

Amount~No matter how well a transmission
system is designed, if it is notproperly lubricated, its service life
will be shortened.

Method~Proper lubrication of roller chains is
a very important factor in getting
their best possible performance andlonger lifetime.

Comparison on Transmission Parts

2010/10/1
Sugiyama Chain co., ltd
Technical Dept.

[ROLLER CHAIN]• Roller Chain, like a timing belt, is used to transmit power. Roller Chain is suitable for powertransmission in slow and medium speed applications.
• There are 13 typical chain sizes from #25 to #240 (#25, #35, #40, #50, #60, #80, #100, #120, #140,#160, #180, #200 and #240).
• Compared to timing belts, roller chain drives have fewer tooth skipping problems.
• Forward/Backward transmission is available with roller chain along multiple shafts. Roller chain canbe use for horizontal, vertical and inclined applications.
• Lubrication is required. Roller chain drives do give off some noise. Drive center distance is flexible.
• Maximum chain speed should be less than 7 m/sec. For general applications, 2~3 m/sec is suitable.
For speeds lower than 0.83m/sec (50m/min), a slow speed selection method should be used.
• Roller chain wrap on the small sprocket should be more than 120 degrees. Normally its output islower than 100kw.
• The normal speed ratio of roller chain can range up to 5:1. High transmission efficiency of 95~98% is
expected.
• The minimum number of sprocket teeth is 13~16. For slow speed applications, sprockets with 9~10
teeth can be used.
• For sprockets smaller than 17 teeth, an odd number of teeth is recommended.
• Optimum distance is 30~50 times the pitch of the chain used. When there is a pulsating load, thedistance should be up to about 20 times.
• Normal application temperature is -10°C~170°C.
[V BELT]• V belts are used for high speed and medium speed transmission.
• Lubrication is not necessary. For this reason, equipment may be smaller.
• They have smaller vibration, shock, and driving noise compared to roller chain drives.
• When oil sticks to the V belt, transmission efficiency is greatly reduced.
• Drive center distance is flexible.
• V belt wrap on the small pulley should be more than 120 degree.
• There is slippage between the V belt and pulley. The slippage is about 1~3%.
• Maximum V belt speed should be less than 25m/sec.
• For general application, 5~18m/sec is suitable.
• Transmission efficiency is 80~95%. Standard speed ratio of V belt is up to 8:1.
• Standard output is less than 75kw. There are 6 types of V belt, of M, A, B, C, D & E.
[TIMING BELT]• Timing belts have teeth to engage the pulley. Non-slip transmission is available.
• They are used as timing belts in automobile-type engines. It is also commonly used for transmission in officeequipment.
• There are 6 sizes of timing belts with pitch ranging from 2.032, 5.08, 9.525, 12.70, 22.225 to 31.75.
• Transmission efficiency is 90~98%.
• Application temperature is -40°C~90°C.
• Pulley alignment is required.

Elastic Elongation

The Elastic Elongation graph shows how much elastic elongation the roller chain will undergo when it issubjected to tension.
The same graph as standard chain can be used for Heavy & Super series.
Results may vary slightly under different conditions.
The elastic limit of Roller Chain is 50% of its tensile strength and that of Stainless Steel Roller Chain is 30%
of its tensile strength.
If you subject chains to tension greater than their elastic limit, they may no longer function properly and may
cause damage or injury.
Never subject chains to tension greater than their elastic limit.

Sprockets for Double Pitch Chain
Fig.1

2010/10/1
Sugiyama Chain co., ltd
Technical Dept.

Fig.2

Large Roller Type

Small Roller TypeAll double pitch chain with large rollers require sprockets designed specifically for their use.
Small roller double pitch chain requires specifically designed sprockets only if using a sprocket with fewer than
30 teeth.
Small roller type double pitch chain engages every other sprocket tooth.
Small roller double pitch chain may use single pitch sprockets of 30 teeth or more.
A sprocket with an odd number of teeth, however, is recommended for small roller type double pitch chain whena sprocket of more than 30 teeth is used.
When using a sprocket with an odd number, each tooth is engaged every other revolution. This doubles the
sprocket life.

The Development and Features of SBR Chain
SBR Chain (started selling in July 1987)
SOLID BUSHING & SOLID ROLLER
The chains consist of seamless components such as solid bushings and rollers.
The chain life is longer than that of curled bushing and rollers due to the higher resistance to elongation.
Sugiyama is the only company in the world that supplies all of its standard chains with solid bushings and solid rollers.

Neo SBR Chain (started selling in July 1997, patent pending)With special coating on its pins and bushings,
Neo SBR chain has greater rust resistance and higher wear resistance for longer chain life.
The improved full-strength connecting link allows for full maximum loads by equally the fatigue strength of the chain itself.

Silver SBR Chain (started selling in July 2002, patent pending)

The chain is made with a special surface treatment.
Both our ANSI type simplex & duplex silver SBR chains have about a 25% higher fatigue strengththan our previous standard chains and other manufacturers standard chains.

Picture-1 Pitting corrosion of dangerous area

Picture-2 Fatigue breakage
Wear-out position

Pitting corrosion position
When pitting corrosion of pin is caused pin's fatigue breakage by sea wind while chains are used outside, As
indicated on Drawing 2, the center of pin becomes the starting point of the fatigue breakage.
Regarding the application such as Straddle Container Carrier in port and Lumber Conveyer Machine, when
chains are used under atmosphere which dangerous area of pin may get corroded, we recommend you speciallycoating pin for anti-pitting corrosion.

Features and Drive Direction of Offset Type Bushed Chain( 21 )[ Features ]1. Offset type bushed chain can be easily connected using only one link unit of the chain.
2. There is very little slippage between the bushing and the sprocket teeth.
[ Superior Wear Resistance ]The correct drive direction of offset type bushed chain is critical.
Generally, the drive center distance of conveyor chain is long and the chain speed is slow.
As a result, each individual chain link contacts the sprocket less often, but each individual sprocket tooth
has more cumulative wear because it comes in contact with the chain's entire length.
This results in more wear to the sprocket than to the chain itself.
Sprocket wear can be reduced by using the proper drive direction.
The recommended drive direction ***(when used as a conveyor chain)*** is indicated in figure 1.
As the chain is pushed, slippage occurs between the pin and bushing of the chain rather
than between the sprocket and chain bushing. Sprocket wear is therefore reduced.
When installed as in Figure 2, there is slippage not only between the pin and the bushing, but also between
the sprocket and the bushing as the chain pulled around the sprocket. This creates more sprocket wear.
In certain other cases, however, the chain drive feed direction should be reversed.
Figure 2 should be referenced in the following applications:
1. When offset chain is used as a power transmission chain rather than a conveyor chain.
2. When the chain runs at a speed high enough to blow away the conveyed product.
3. When used as a Drag chain (the flat side of the barrel is used as a scraper).

【Measuring method】
Chain must be measured with approxmatly one % of the minimum breaking strength applied.
② Elongation measuring （caliper）
As indicated bellow, about 6 to 10 links are measured.
measured length ＝

L1 + L2

③ Elongation measuring（tape measure）
This can be done by removing the chain from the sprockets and hanging in a vertical position or
placing on a flat horizontal surface and applying the measuring load needed for each individual
size chain.
