Technical Information
GearMe Aluminum Group 1, 2, and 3 Motor
General information
Overview
The DanfossGear Motors is a range of peak performance fixed displacement hydraulic motors available inthree different frame sizes: Group 1, Group 2, and Group 3, all as uni- and bidirectional version.
Constructed of a high strength extruded aluminum body with aluminum rear cover and aluminum front
flange, all motors are balanced for exceptional efficiency and designed to ensure an excellent starting
torque and, in the bidirectional version, to guarantee the ability to work with high back pressure andextremely low system pressure.
The flexibility of the range in each frame size combined with the high efficiency and low starting torquemakes the Danfoss Gear Motors ideal for a wide range of applications sectors including on- and offhighway hydraulic fan drive systems, turf care, road bildge, fork lifts and municipal.
All the unidirectional motors have the same construction of the correspondent pump as well but, with
inlet and outlet positioned at the opposite side for the same rotation.

System Requirements
Pressure
Peak pressure is the highest intermittent pressure allowed.
The relief valve overshoot (reaction time) determines peak pressure. It is assumed to occur for less than
100 ms.
The illustration to the right shows peak pressure in relation to rated pressure and reaction time (100 ms
maximum).
Rated pressure is the average, regularly occurring operating inlet pressure that should yield satisfactory
product life. The maximum machine load at the motor shaft determines rated pressure
Pressure

Peak pressure
Rated pressure

Reaction time (100 ms max)Time

System pressure is the differential between the inlet and outlet ports. It is a dominant operating variableaffecting hydraulic unit life. High system pressure, resulting from high load at the motor shaft, reduces
expected life. System pressure must remain at, or below, rated pressure during normal operation toachieve expected life.
Back pressure is the average, regularly occurring operating outlet pressure that should yield satisfactorybidirectional motor life. The hydraulic load demand downstream of the motor determines the backpressure. Unidirectional motors cannot work with back pressure and the maximum back pressure
allowed is 5 bar [72 psi] rated and 7 bar [101 psi ] as peak.
Case Drain Pressure is the regularly occurring case drain line pressure that should yield satisfactorybidirectional motor life. It is recommended to design the case drain piping connecting the case drain
direct to the tank in order to keep the case drain pressure as low as possible. The max. continuous casedrain pressure allowed is 5 bar [72 psi] rated and 7 bar [101 psi] as peak.
Speed
Maximum speed is the limit recommended by Danfoss for a particular gear motor when operating at
rated pressure. It is the highest speed at which normal life can be expected.
The lower limit of operating speed is the minimum speed. It is the lowest speed at which normal life canbe expected.
The minimum speed increases as operating system pressure increases. When operating under higher
pressures, a higher minimum speed must be maintained, as illustrated below.

Hydraulic Fluids
Ratings and data for GearMe Group 1, 2, and 3 motors gear motors are guaranteed when the hydraulicsystem operates with premium hydraulic fluids without containing oxidation, rust, or foam inhibitors.
These fluids have to work with good thermal and hydrolytic stability to prevent wear, erosion, or
corrosion of internal components. They include:• Hydraulic fluids following DIN 51524, part 2 (HLP) and part 3 (HVLP) specifications• API CD engine oils conforming to SAE J183
• M2C33F or G automatic transmission fluids• Certain agricultural tractor fluids

C Caution
Use only clean fluid in the gear motors and hydraulic circuit. Never mix hydraulic fluids.

Temperature and Viscosity
Temperature and viscosity requirements must be concurrently met. Use of petroleum/mineral-based
fluids is highly recommended.
High temperature limits apply at the inlet port of the motors. The motors should operate at or below the
maximum continuous temperature. The peak temperature is based on material properties.
Don’t exceed it.
Minimum (cold start) temperature relates to the physical properties of component materials.
Cold oil, generally, doesn’t affect the durability of motors components. It may affect the ability of oil toflow and transmit power. For this reason, keep the temperature at 16°C [60 °F] above the pour point of
the hydraulic fluid.

Filters
Use a filter that conforms to Class 22/18/13 of ISO 4406 (or better). It may be on the motor outlet(discharge filtration) or inlet (pressure filtration).
Selecting a filter
When selecting a filter, please consider:Contaminant ingression rate (determined by factors such as the number of actuators used in thesystem)• Generation of contaminants in the system• Required fluid cleanliness• Desired maintenance interval• Filtration requirements of other system components•

Measure filter efficiency with a Beta ratio (βX). βx ratio is a measure of filter efficiency defined by ISO 4572.
It is the ratio of the number of particles greater than a given diameter (in microns) upstream of the filter
to the number of these particles downstream of the filter.
• For discharge filtration with controlled reservoir ingression, use a β35-45 = 75 filter• For pressure filtration, use a filtration with an efficiency of β10 = 75
The filtration requirements for each system are unique. Evaluate filtration system capacity by monitoring
and testing prototypes.

The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows fluid volume
changes associated with fluid expansion and cylinder differential volumes. A correctly sized reservoir© Danfoss | February 2023

BC319483612502en-000104 | 11

Technical Information
GearMe Aluminum Group 1, 2, and 3 Motor
System Requirements
accommodates maximum volume changes during all system operating modes. It promotes de-aerationof the fluid as it passes through, and accommodates a fluid dwell-time between 60 and 180 seconds,
allowing entrained air to escape.
Minimum reservoir capacity depends on the volume required to cool and hold the oil from all retracted
cylinders, allowing for expansion due to temperature changes. A fluid volume of 1 to 3 times the pump
output flow (per minute) is satisfactory. The minimum reservoir capacity is 125% of the fluid volume.
Install the suction line above the bottom of the reservoir to take advantage of gravity separation andprevent large foreign particles from entering the line. Cover the line with a 100-125 micron screen. The
pump should be below the lowest expected fluid level.
Put the return-line below the lowest expected fluid level to allow discharge into the reservoir for
maximum dwell and efficient deaeration. A baffle (or baffles) between the return and suction lines
promotes deaeration and reduces fluid surges.
Line sizing-x
Choose pipe sizes that accommodate minimum fluid velocity to reduce system noise, pressure drops, andoverheating. This maximizes system life and performance.
Design inlet piping that maintains continuous pump inlet pressure above 0.8 bar absolute during normal
operation. The line velocity should not exceed the values in the table below:
Maximum line speed
Inlet

OutletReturn5 m/s [16.4 ft/sec]

2.5 m/s [8.2 ft/sec]

3 m/s [9.8 ft/sec]

Most systems use hydraulic oil containing 10% dissolved air by volume.
Over-aeration, or entrained air is the result of flow line restrictions, where the dissolved air comes outof solutions, or when air is allowed to leak into the hydraulic circuit. These include inadequate pipes size,
sharp bends, or elbow fittings causing a reduction of flow-line cross-sectional area. This problem will notoccur if these circuit recommendations are followed, rated speed requirements are maintained, andreservoir size and location are adequate.
Motor shaft connection
Shaft options for gear motors include tapered, splined, and parallel shafts.
Plug-in drives, with a splined shaft, can impose severe radial loads when the mating spline is rigidly
supported. Increasing spline clearance does not alleviate this condition.
Use plug-in drives only if the concentricity between the mating spline and pilot diameter is within 0.1
mm [0.004 in]. Lubricate the drive by flooding with oil. A three-piece coupling minimizes radial or thrust
shaft loads.

Motor Life
Motor life is a function of speed, system pressure, and other system parameters (such as fluid quality andcleanliness).
All Danfoss gear motors use hydrodynamic journal bearings that have an oil film maintained between thegear/shaft and bearing surfaces at all times. If the oil film is sufficiently sustained through proper system
maintenance and operating within recommended limits, long life can be expected.
High pressure impacts motor life. When submitting an application for review, provide machine duty cycle
data that includes percentages of time at various loads and speeds.
B10 life expectancy number is generally associated with rolling element bearings. It does not exist forhydrodynamic bearings.
Danfoss strongly recommends a prototype testing program to verify operating parameters and theirimpact on life expectancy before finalizing any system design.

SAE spline J 498-9T-20/40DP--

Recommended mating splines for Group 1 splined output shafts should be in accordance with SAE J498
or DIN 5482. Danfoss external SAE splines are flat root side fit with circular tooth thickness reduced by
0.127 mm [0.005 in] in respect to class 1 fit. The external DIN splines have an offset increased by 0.1 mm[0.004 in]. These dimensions are modified in order to assure a clearance fit with the mating spline.
Other shaft options may exist. Contact your Danfoss representative for availability.

C Caution
Shaft torque capability may limit allowable pressure. Torque ratings assume no external radial loading.
Applied torque must not exceed these limits, regardless of stated pressure parameters. Maximum torqueratings are based on shaft torsional fatigue strength.

Integral relief value - SKM1IN
Danfoss offers an optional integral relief valve integrated in the Group 1 motors rear cover. It is drainedinternally and directs all the flow from the motor inlet to the outlet when the inlet pressure reaches thevalve setting.
The tables below show applicable variant codes for ordering motors with integral relief valve. Refer toModel code on page 15 for more information.

Shaft options
Group 2 motors are available with a variety of splined, parallel, and tapered shaft ends. Not all shaft styles
are available with all flange styles.
Valid combinations and nominal torque ratings are shown in the following table. Torque ratings assume
no external radial loading. Applied torque must not exceed these limits regardless of pressure
parameters stated earlier. Maximum torque ratings are based on shaft torsional fatigue strength.

Recommended mating splines for Group 2 splined output shafts should be in accordance with SAE J498
or DIN 5482. Danfoss external SAE splines are flat root side fit with circular tooth thickness reduced by
0.127 mm [0.005 in] in respect to class 1 fit. The external DIN splines have an offset increased by 0.1 mm[0.004 in.] These dimensions are modified in order to assure a clearance fit with the mating spline.
Other shaft options may exist. Contact your Danfoss representative for availability.

C Caution
Shaft torque capability may limit allowable pressure. Torque ratings assume no external radial loading.
Applied torque must not exceed these limits, regardless of stated pressure parameters. Maximum torqueratings are based on shaft torsional fatigue strength.

Outrigger bearing assembly - SNM2NN
An outrigger bearing is available for applications with high radial or thrust loads on the shaft. This option
is used primarily for applications with high shaft loads. The design utilizes roller bearings in the front
mounting flange. These bearings absorb the radial and thrust loads on the shaft so that the life of the
motor is not affected. The use of roller bearings allows life to be described in B10 hours.
