OVERVIEW The Sauer-Danfoss Gear Motors is a range of peak performance fixed displacement hydraulic motors available in three different frame sizes: Group 1, Group 2 and Group 3, all as uni- and bi-directional 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 bi-directional version, to guarantee the ability to work with high back pressure and extremely low system pressure.
The flexibility of the range in each frame size combined with the high efficiency and low starting torque makes the Sauer-Danfoss Gear Motors ideal for a wide range of applications sectors including on- and off-highway hydraulic fan drive systems, turf care, road bildge, fork lifts and municipal.
All the uni-directional 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.

PRESSURE
SPEED
System Requirements
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.
Maximum speed is the limit recommended by Sauer-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 can be expected. The minimum speed increases as operating system pressure increases. When operating under higher pressures, a higher minimum speed must be maintained, as illustrated to the right.

Time versus pressure
Speed versus pressure
System pressure is the differential between the inlet and outlet ports. It is a dominant operating variable affecting 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 to achieve expected life.
Back pressure is the average, regularly occurring operating outlet pressure that should yield satisfactory bidirectional motor life. The hydraulic load demand downstream of the motor determines the back pressure. 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 satisfactory bi-directional motors 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 case drain pressure allowed is 3 bar [44 psi].

Temperature and viscosity requirements must be concurrently satisfied. Use petroleum/mineral-based fluids.
High temperature limits apply at the inlet port of the motor. The motor should run at or below the maximum continuous temperature. The peak temperature is based on material properties. Don’t exceed it.
Cold oil, generally, doesn’t affect the durability of motor components. It may affect the ability of oil to flow and transmit power. For this reason, keep the temperature at 16°C [60 °F] above the pour point of the hydraulic fluid.
Minimum (cold start) temperature relates to the physical properties of component materials.
Minimum viscosity occurs only during brief occasions of maximum ambient temperature and severe duty cycle operation. You will encounter maximum viscosity only at cold start. During this condition, limit speeds until the system warms up. Size heat exchangers to keep the fluid within these limits. Test regularly to verify that these temperatures and viscosity limits aren’t exceeded. For maximum unit efficiency and bearing life, keep the fluid viscosity in the recommended viscosity range.

Ratings and data for gear motors are based on operating with premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion, and 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
Use only clean fluid in the motor and hydraulic circuit.
C CautionNever mix hydraulic fluids.
Please see Sauer-Danfoss publication Hydraulic Fluids and Lubricants Technical Information, 520L0463 for more information. Refer to publication Experience with Biodegradable Hydraulic Fluids Technical Information, 520L0465 for information relating to biodegradable fluids.

FiltersUse 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 filterWhen selecting a filter, please consider:• contaminant ingression rate (determined by factors such as the number of actuators
used in the system)• 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):
• for discharge filtration with controlled reservoir ingression, use a β35-45
= 75 filter• for pressure filtration, use a filtration with an efficiency of β
10 = 75
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 ( “X“ in microns) upstream of the filter to the number of these particles downstream of
the filter.

Recommended inlet screen size 100 – 125 µm [0.0039 – 0.0049 in]
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 for fluid volume changes associated with fluid expansion and cylinder differential volumes. A correctly sized reservoir accommodates maximum volume changes during all system operating modes. It promotes deaeration of 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, allowing for expansion due to temperature changes. A fluid volume of one to three times the motor output flow (per minute) is satisfactory. The minimum reservoir capacity is 125% of the fluid volume.
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.

MOTOR SHAFT CONNECTION Pilot cavity
Ø 0.1 [0.004]
P101 002E
Mating spline
Shaft options for gear motors include tapered, splined, parallel or Sauer-Danfoss tang 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 if the concentricity between the mating spline and pilot diameter is within 0.1 mm [0.004 in]. Lubricate the drive by flooding it with oil. A three-piece coupling minimizes radial or thrust shaft loads.
Choose pipe sizes that accommodate minimum fluid velocity to reduce system noise, pressure drops, and overheating. This maximizes system life and performance. The line velocity should not exceed the values in this table:
Maximum line velocityInlet
m/s [ft/sec]
2.5 [8.2]
Outlet 5.0 [16.4]
Return 3.0 [9.8]
Most systems use hydraulic oil containing 10% dissolved air by volume. Over-aeration is the result of the flow-line restrictions. These include inadequate pipe sizes, sharp bends, or elbow fittings, causing a reduction of flow line cross sectional area. This problem will not occur if rated speed requirements are maintained, and reservoir size and location are adequate.
C CautionIn order to avoid spline shaft damages it is recommended to use carburised and hardened steel couplings with 80-82 HRA surface hardness.
Allowable radial shaft loads are a function of the load position, load orientation, and operating pressure of the hydraulic motor. All external shaft loads have an effect on bearing life, and may affect motor performance.
In applications where external shaft loads can not be avoided, minimize the impact on the motor by optimizing the orientation and magnitude of the load. Avoid thrust loads in either direction. Please contact Sauer-Danfoss, if continuously applied external radial or thrust loads occur.

System Requirements
Motor life is a function of speed, system pressure, and other system parameters (such as fluid quality and cleanliness).
All Sauer-Danfoss gear motors use hydrodynamic journal bearings that have an oil film maintained between the gear/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.
B10
life expectancy number is generally associated with rolling element bearings. It does not exist for hydrodynamic bearings.
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. We strongly recommend a prototype testing program to verify operating parameters and their impact on life expectancy before finalizing any system design.

MOUNTING FLANGES
Group 1 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 table below.

Recommended mating splines for Group 1 splined output shafts should be in accordance with SAE J498 or DIN 5482. Sauer-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 Sauer-Danfoss representative for availability.
C CautionShaft 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 torque ratings are based on shaft torsional fatigue strength.
Sauer-Danfoss offers many types of industry standard mounting flanges. The table below shows order codes for each available mounting flange and its intended use:

Recommended mating splines for Group 2 splined output shafts should be in accordance with SAE J498 or DIN 5482. Sauer-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 Sauer-Danfoss representative for availability.
C CautionShaft 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 torque ratings are based on shaft torsional fatigue strength.

SNM2J.Sauer-Danfoss offers the Group 2 motors with an optional integral relief valve integrated in the rear cover and anti-cavitation check valve integrated in the bearing block. The integral relief valve is drained internally and directs all the flow from the motor inlet to the outlet when the inlet pressure reaches the valve setting. The anti-cavitation check valve directs internally the flow from the motor outlet to the inlet, when the outlet pressure gets higher then the inlet one.
Product Options
INTEGRAL RELIEF VALVE AND ANTI-CAVITATION CHECK VALVE – SNM2J.
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 pump is not affected. The use of roller bearings allows life to be described in B
10 hours.

Recommended mating splines for Gr3 splined output shaft in accordance to SAE J498 or DIN5482. Sauer-Danfoss external SAE splines have a flat root side fit with circular tooth thickness reduced by 0.127 mm [0.005 in] in respect to class 1 fit. Dimensions are modified to assure a clearance fit with the mating spline.
Other shaft options may exist. Contact your Sauer-Danfoss representative for availability.
C CautionShaft 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 torque ratings are based on shaft torsional fatigue strength.
Sauer-Danfoss offers many types of industry standard mounting flanges. This table shows order codes for each available mounting flange and its intended use:
/
Flange code Intended use
01 European 01 flange ø50.8 mm [Dia 2.0 in] 4-Bolt
02 European 02 flange ø50.8 mm [Dia 2.0 in] 4-Bolt
03 European ø60.3 mm [Dia 2.374 in] 4-Bolt
06 German ø105 mm [Dia 4.134 in] 4-Bolt
07 SAE B 2-Bolt
Group 3 motors are available with a variety of splined, parallel, and tapered shaft ends. Not all shaft styles are available with all flange styles.
