ZMSS Bearingless Orbital Hydraulic Motor
The OMS Short Version Orbital Hydraulic Motor (ZMSS/OMSS) features a compact design without a built-in output shaft, making it ideal for applications with limited installation space. It uses a disc valve distribution system for smoother operation and higher efficiency under high pressure. The geroler stator and rotor structure reduces wear, providing longer service life, stable low-speed performance, and reliable high-torque output.
- Product Introduction


Key Design Features
Short Version (No Output Shaft): It lacks a built-in output shaft and front bearing housing. It relies on the shaft of an external mating device (typically an internal spline connection) to transmit torque.
Compactness: Due to the elimination of the front bearing support, its length is significantly shorter than a standard OMS motor, making it ideal for applications with extremely limited installation space.
Distribution System: Employs a disc valve distribution system, which is more efficient and smoother under high pressure than shaft distribution.
Structure of Stator and Rotor Set: Utilizes a geroler set structure, reducing direct wear on the gear teeth, resulting in a longer service life, smoother low-speed operation, higher overall efficiency, and the ability to withstand higher operating pressures.
