The motors size vary (rated displacement) from 130 to 800 cm3 [7.9 to 48.9 in3] per revolution.• Motor sizes:
‒ OMT and OMV
‒ TMK
‒ TMT
‒ TMTHW
‒ TMVW
Speeds range up to approximate 600 min-1 (rpm).

The bar diagrams above are useful for a quick selection of relevant motor size for the application. Thefinal motor size can be determined by using the function diagram for each motor size: see OMT Functiondiagrams on page 14, or OMV function diagrams on page 45.
The function diagrams are based on actual tests on a representative number of motors from ourproduction. The diagrams apply to a return pressure between 5 and 10 bar [75 and 150 psi] when usingmineral based hydraulic oil with a viscosity of 35 mm2/s [165 SUS] and a temperature of 50°C [120°F].

Permissible shaft loads for OMT
Mounting flange:

Shaft:
All shaft types
Mounting flange:
Wheel
Shaft:
All shaft types
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 fromthe mounting flange to the point of load application.
The curve is based on B10 bearing life (2000 hours or 12,000,000 shaft revolutions at 100 min-1) at ratedoutput torque, when mineral-based hydraulic oil with a sufficient 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 maximum radial shaft load. Any shaft load exceeding the values shown in thecurve will involve a risk of breakage.
Bearing life calculations can be made using the explanation and formula provided in the chapter "Bearingdimensioning in the technical information General Orbital Motors, BC152886483554.

OMTS
Installation
The cardan shaft of the OMTS motor acts as an “output shaft”. Because of the movement of the shaft, noseal can be fitted at the shaft output.
Internal oil leakage from the motor will therefore flow into the attached component.
During start and operation it is important that the spline connection and the bearings in the attachedcomponent receive oil and are adequately lubricated. To ensure that the spline connection receivessufficient oil, a conical sealing ring between the shaft of the attached component and the motorintermediate plate is recommended. This method is used in the OMT.
The conical sealing ring (code. no. 633B9022) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the stop plate musthave a hole in it (see fig. below).
We recommend an O-ring between motor and attached component. The O-ring (code no. 151B1040) issupplied with the motor. If motor and attached component have been separated, remember to refillbefore starting up. Fill the oil through the drain connection.
* The gearwheel set is 3.5 mm [0.138 in] wider across the rollers than the L1 dimensions

Motor or attached component drain connection
Use the drain line when pressure in the return line exceeds the permissible pressure on the shaft seal ofthe attached component.
Connect the drain line either at the:• Motor drain connection• Drain connection of the attached component
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motorand attached component.
The drain line must be led to the tank in such a way that there is no risk of the motor and attachedcomponent being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its shaft seal.

Permissible shaft loads
Shaft load and bearing life time
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 fromthe mounting flange to the point of load application.
The curve is based on B10 bearing life (2000 hours or 12,000,000 shaft revolutions at 100 min-1) at ratedoutput torque, when mineral-based hydraulic oil with a sufficient 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 maximum radial shaft load. Any shaft load exceeding the values shown in thecurve will involve a risk of breakage.
Bearing life calculations can be made using the explanation and formula provided in the chapter Bearingdimensioning in the technical information General Orbital Motors, BC152886483554.

Installing the OMVS
The cardan shaft of the OMVS motor acts as an “output shaft”. Because of the movement of the shaft, noseal can be fitted at the shaft output.
Internal oil leakage from the motor will therefore flow into the attached component.
During start and operation it is important that the spline connection and the bearings in the attachedcomponent receive oil and are adequately lubricated. To ensure that the spline connection receivessufficient oil, a conical sealing ring between the shaft of the attached component and the motorintermediate plate is recommended. This method is used in the OMV.
The conical sealing ring (code. no. 633B9021) is supplied with the motor.
To ensure that oil runs to the bearings and other parts of the attached component, the stop plate musthave a hole in it (see fig. below).
We recommend an O-ring between motor and attached component. The O-ring (code no. 151B1041) issupplied with the motor. If motor and attached component have been separated, remember to refillbefore starting up. Fill the oil through the drain connection.

Motor or attached component drain connection
Use the drain line when pressure in the return line exceeds the permissible pressure on the shaft seal ofthe attached component.
Connect the drain line either at the:• Motor drain connection• Drain connection of the attached component
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motorand attached component.
Technical InformationOMT and OMV Orbital Motors

The drain line must be led to the tank in such a way that there is no risk of the motor and attachedcomponent being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its shaft seal.
