 Specifications MR HR RL  Service Manual MR HR
- Orbiting roller set
- Spool valve integrated with output shaft
- Output shaft supported in hydrodynamic bearings
- Output shaft supported in needle bearings
MR Series have a spool valve: the distribution valve is integrated in the outpust shaft. The cardan shaft thus rotates the distribution valve and mechanical energy from the gerotor set to the output shaft.
OPTIONS
- Model - Spool valve, roll-gerotor;
- Flange and wheel mount;
- Motor with needle bearings; -side and rear ports; - Speed sensor connection;
- Shafts - straight, splined and tapered;
- High pressure shaft seal;
- BSPP and UNF parts;
- Other special features. | Code | Displa-

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder. Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump because it performs the opposite function - much as the conceptual DC electric motor is interchangeable with a DC electrical generator. However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for the working pressure at both sides of the motor.
Hydraulic pumps, motors, and cylinders can be combined into hydraulic drive systems. One or more hydraulic pumps, coupled to one or more hydraulic motors, constitutes a hydraulic transmission. |
