Low-speed, high-torque motors

March 22, 2007
WR Series of low-speed, high-torque hydraulic motors feature flow rates to61-lpm, torque to 66-Nm, and pressures to 172 bar.

WR Series of low-speed, high-torque hydraulic motors feature flow rates to 61-lpm, torque to 66-Nm, and pressures to 172 bar. Seven precision rollers eliminate sliding friction and improve motor efficiency. A three-zone spool valve, integral check valves, and provision fora case drain reduce pressure on internal seals and improve seal life. A smaller eccentric rotor set enhances the smooth operation of the motor and increases drive-link life. Heavy-duty drive links with special features reduce drag,increase motor efficiency, and increase spline life. Twelve displacements are available ranging from 40 to 404 cc/rev. Several mounting, shaft, and porting options are available.
