Hydraulic Motors

HMB Series

The Kawasaki “Staffa” HMB Series range of high torque low speed fixed displacement radial piston hydraulic motors consists of 12 frame sizes ranging from the HMB010 to HMHDB400. Capacity ranges from 50 to 6,800 cc/rev. The rugged, well proven design incorporates high efficiency, combined with good breakout torque and smooth running capability.

Bearing Life:

Consideration should be taken upon the required motor in terms of bearing service life. The factors that will determine bearing life include:

  • Duty Cycle
  • Differential Pressure
  • Fluid Viscosity
  • Speed
  • External Radial Shaft Load
  • External Axial Shaft Load

Various features and options are available -

  • Capacities from 50 to 6800 cc per rev.
  • Fixed, dual or quad displacement.
  • Up to 250 bar max continuous pressure.
  • Output to 25000 Nm. Continuous power up to 430kW.
  • Unique hydrostatic balancing provides minimum wear and extended life.
  • High volumetric and mechanical efficiency.
  • Large variety of shaft and porting options.
  • On dual / quad displacement motors, the pre-set displacements can be selected with ease when the motor is running including a freewheel option.
  • Also available in a continuously variable version using either hydro-mechanical or electro-hydraulic control methods.
  • Highly accurate electronic positional and velocity control systems available.
  • Digital Smart Motor’ with integral fully submersible shaft torque sensor system can be used for winch tensioning systems up to a motor shaft torque of 25000 Nm.
  • Fixed, dual or quad displacement.
