The BMH 500 cycloidal hydraulic motor is a high-performance hydraulic motor that adopts advanced Geroler® Inserted tooth stator and rotor technology, with a geometric displacement of 489.2 ml/r (approximately 500cc). This model belongs to the BMH/OMH series and is renowned for its robust structure capable of withstanding high radial forces and extensive international interchangeability. It is an ideal alternative to international brand models such as Danfoss OMH 500 and M+S MH 500 - 1. The product is equipped with a 4-bolt mounting flange and a 31.75mm (1.25-inch) cylindrical straight shaft, and adopts an axial flow distribution design, which can automatically compensate under high pressure, providing reliable, stable operation and high efficiency. It is widely used in construction machinery, agricultural machinery, industrial equipment and other fields.

Advanced Geroler® Roller Stator-Rotor Technology

Features low starting pressure and high starting torque for smooth, reliable heavy-load startup. Delivers high and sustained volumetric efficiency, with automatic wear compensation to extend service life.

High Radial Load Capacity

Equipped with heavy-duty bearings to withstand high radial and axial loads, suitable for direct sprocket, gear or belt drives. The robust cast iron housing ensures excellent resistance to harsh environments and impact loads.

Full International Interchangeability

Offers 1:1 direct replacement for Danfoss OMH 500, M+S MH 500 and equivalent models, with no modifications required. As a standard BMH/OMH series unit, it benefits from global spare parts availability.

The BMH 500 hydraulic motor, with its high torque output and high radial load-carrying capacity, is widely used in the following equipment:

1. Engineering and construction machinery
Cranes, construction machinery
Heavy equipment drives
Mining machinery
Tunnel engineering equipment

2. Agricultural and forestry machinery
Agricultural machinery (large harvesters, sprayers)
Forestry machinery (skidders, crushers)
Garden maintenance equipment

3. Industrial and material handling
Conveyor belt drives
Winches and hoisting equipment
Sawmill equipment
Lifting platforms
