Sauer-Danfoss is a world leader within production of low speed orbital motors with
high torque. We can offer more than 1600 different orbital motors, categorised in types,
variants and sizes (incl. different shaft versions).
The motors vary in size (rated displacement) from 8 cm
3
[0.50 in

]
to 800 cm
3
[48.9 in

]
per revolution.
Speeds range up to approx. 2500 min
-1
(rpm) for the smallest type and up to approx
600 min
-1
(rpm) for the largest type.
Maximum operating torques vary from 13 Nm [115 lbf·in] to 2700 Nm [24.000 lbf·in]
(peak) and maximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].
Characteristic features:
• Smooth running over the entire speed range
• Constant operating torque over a wide speed range
• High starting torque
• High return pressure without the use of drain line (High pressure shaft seal)
• High effi ciency
• Long life under extreme operating conditions
• Robust and compact design
• High radial and axial bearing capacity
• For applications in both open and closed loop hydraulic systems
• Suitable for a wide variety of hydraulics fl uids

The programme is characterised by technical features appealing to a large number
of applications and a part of the programme is characterised by motors that can be
adapted to a given application. Adaptions comprise the following variants among others:
• Motors with corrosion resistant parts
• Wheel motors with recessed mounting fl ange
• OMP, OMR- motors with needle bearing
• OMR motor in low leakage version
• OMR motors in a super low leakage version
• Short motors without bearings
• Ultra short motors
• Motors with integrated positive holding brake
• Motors with integrated negative holding brake
• Motors with integrated fl ushing valve
• Motors with speed sensor
• Motors with tacho connection
• All motors are available with black fi nish paint
Planetary gears
Sauer-Danfoss complements the motor range with a complete programme of planetary
gears adapted to suit. The combination of motors and gears makes it possible to obtain
smooth running at fractional speeds and with torques up to 650.000 Nm (5.800.000 lbf·in).
The Sauer–Danfoss orbital motors are used in the following application areas:
• Construction equipment
• Agricultural equipment
• Material handling & Lifting equipment
• Forestry equipment
• Lawn and turf equipment
• Special purpose
• Machine tools and stationary equipment
• Marine equipment
Detailed data on all Sauer-Danfoss motors can be found in our motor catalogue, which is
divided into 5 individual subcatalogues:
• General information on Sauer-Danfoss orbital motors: function, use, selection of
orbital motor, hydraulic systems, etc.
• Technical data on small motors: OML and OMM
• Technical data on medium sized motors: OMP, OMR, OMH and OMEW
• Technical data on medium sized motors: DH and DS
• Technical data on large motors: OMS, OMT and OMV
• Technical data on large motors: TMT
A general survey brochure on Sauer-Danfoss orbital motors gives a quick motor
reference based on power, torque, speed and capabilities.

The bar diagrams above are useful for a quick selection of relevant motor size for the
application. The fi nal motor size can be determined by using the function diagram for
each motor size.
• OMS can be found on pages 14-18
• OMT can be found on pages 42-44
• OMV can be found on pages 65-67
The function diagrams are based on actual tests on a representative number of motors
from our production. The diagrams apply to a return pressure between 5 and 10 bar
[75 and 150 psi] when using mineral based hydraulic oil with a viscosity of 35 mm

/s
[165 SUS] and a temperature of 50°C [120°F]. For further explanation concerning how
to read and use the function diagrams, please consult the paragraph "Selection of

The output shaft runs in tapered roller bearings that permit high axial and radial forces.
The permissible radial load on the shaft is shown for an axial load of 0 N as a function of
the distance from the mounting fl ange to the point of load application.
The curve is based on B10 bearing life (2000 hours or 12,000,000 shaft revolutions at

) at rated output torque, when mineral-based hydraulic oil with a suffi cient
content of anti-wear additives, is used.
For 3,000,000 shaft revolutions or 500 hours – increase these shaft loads with 52%.
The dash curve shows max. radial shaft load. Any shaft load exceeding the values shown
in the curve will involve a risk of breakage.

content of anti-wear additives, is used.
For 3,000,000 shaft revolutions or 500 hours – increase these shaft loads with 52%.
The dash curve shows max. radial shaft load. Any shaft load exceeding the values shown
in the curve will involve a risk of breakage.
Bearing life calculations can be made using the explanation and formula provided in

INSTALLING THE OMSS
OMSS
DIMENSIONS OF THE
ATTACHED COMPONENT
The cardan shaft of the OMSS motor acts as an “output shaft”. Because of the movement
of the shaft, no seal can be fi tted at the shaft output.
Internal oil leakage from the motor will therefore fl ow into the attached component.
During start and operation it is important that the spline connection and the bearings
in the attached component receive oil and are adequately lubricated. To ensure that the
spline connection receives suffi cient oil, a conical sealing ring between the shaft of the
attached component and the motor intermediate plate is recommended. This method
is used in the OMS.
The conical sealing ring (code. no. 633B9023) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the
stop plate must have a hole in it (see fi g. below).
We recommend an O-ring between motor and attached component. The O-ring
(code no. 151F1033) is supplied with the motor. If motor and attached component have
been separated, remember to refi ll before starting up. Fill the oil through the drain
connection.

The attached component must have internal splines corresponding to the external
splines on the motor cardan shaft (see drawing below).
Material:
Case hardening steel with a tensile strength corresponding at least to 20 MoCr4
(900 N/mm

) or SAE 8620.

INTERNAL SPLINE DATA
FOR THE COMPONENT TO
BE ATTACHED
DRAIN CONNECTION ON
OMSS OR ATTACHED
COMPONENT
A drain line ought to be used when pressure in the return line can exceed the permissible
pressure on the shaft seal of the attached component.
The drain line can be connected at two different points:
1) at the motor drain connection
2) at the drain connection of the attached component.
If a drain line is fi tted to the attached component, it must be possible for oil to fl ow freely
between motor and attached component.
The drain line must be led to the tank in such a way that there is no risk of the motor and
attached component being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its
shaft seal.
