the optimum viscosity range is 10-39 cSt [60-180 SUS], 

at normal operating temperatures. Viscosity should never fall below 6 cSt [45 SUS].

Axial piston motors share the design advantages of piston pumps to provide long-lasting power in a lightweight,

per milliliter greater than 15 µm.  When components with different cleanliness requirements are used in the same system,

the cleanest standard shoud be appllied. Fluid Recommendations (Refer to Eaton’s 

Hydraulic Fluid Recommendations Technical Data sheet #3-401) 

Dual Rotation     Various Porting Options     Fixed Displacements

Eaton Medium duty piston motors convert hydraulic energy supplied by the pump to mechanical energy. 

These motors are uniquely suited to fit any appliction 

that requires continuous rotary motion at a remote location from the power source.

Case Drain Installation Requirements CAUTION - Failure to meet these requirements may result in damage to the piston motor. 

• Install piston motors in such a position that the case drain assures an oil level at 

or above unit center line. • Oil level must be at or above the unit center line before starting the piston motor. •

 Provide a case drain line of adequate size to limit the case  pressure to specified maximum.
