The MS orbital hydraulic motors are designed for continuous work in heavy duty conditions. The output shaft runs on tapered roller bearings and can absorb high axial and radial forces. The MS series consists of models with maximum rotational speed from 6 through 810 rpm and maximum power range: 7 to 18 kW.
Rotational speed range: from 6 through 810 rpm; maximum continuous pressure: up to 210 bar.
The MS motors have roll-gerotor set and the rollers reduce local stress. The internal gear transmits the torque generated by the application of pressure from hydraulic oil fed into motor which is then delivered via the motor’s output shaft. The output shaft runs on tapered roller bearings and can absorb high axial and radial forces. The MS series consists of eight models with displacement from 80.5 to 200 cm3 and power up to 18 kW.
These motors are used in similar application as MP motors but the MS motors can work in heavy duty conditions and where low rotational speed is requied. The MS motors provide much higher torque than MP motors.
Features:
- Displacement: 80.5 – 200 cm3/rev;
- Rotational speed range: 6 – 1600 rpm;
- Maximum pressure: 210/295 bar (continuous/peak);
- Maximum power: 15.5 – 18 kW.
Advantages:
- Low starting pressure;
- Reinforced shaft seals;
- The motor can be used in parallel or series configurations;
- Low noise level;
- Easy installation;
- Higher torque and power than MP motors.
Applications:
The MS motors are used agricultural and forestry industry, e.g. rakes, conveyors and grinding machines. They are assembled in forklifts, conveyors, trucks, drives and in building industry (small loaders etc.).
