HSM series hydraulic motor is a new type of product of our company which is based on practical experience. The design is improved in the foundation on the original technologies. HSM hydraulic motor mainly has The Following Characteristics.

  • As the piston and the tilt cylinder has no force, the piston motor is designed to be static pressure balance. The torsional force is transferring between the piston and the crankshaft through rolling bearing so the friction loss during the transferring process of force is reduced. therefore, HSM series hydraulic motor has such feature as very high mechanically efficiency and comparatively high startup torque (mechanically efficiency of the over 0.92 during startup.
  • The plane distributor (patented technology) is simple and reliable with perfect seal performance, the product has perfect stability at low speed. it can stably run at 10r/min working condition and has big speed regulation range.
  • As the piston is jointed closely with bearing bushing without any clearance, this series is of hydraulic motor  can run at pump working condition.
  • This series hydraulic motor has high pressure (the highest pressure can reach 315 bar) light weight, small bulk and high specific power.
  • As this series hydraulic motor has simple structure reasonable design and adopts bearing with big load ability, it can work reliably and has long life and low noise the transmission shaft allows endure radial load and the rotational direction is reversible.
