GKB Series Orbital Motor

GRH has GP, GR, GH, GS, GT, GV, GGM, GKA, GKB, GKC, GWD, GFA series orbital motors, GKB series orbital motor is a hydraulic motor with a disk distribution orbital motor. This series of motors uses a built-in rotor and stator set design. It has the characteristics of high working pressure, high working efficiency, and long working life. Multi-functional variant design can be carried out on the basis of standard structure according to different application requirement. Its characteristics:

• Adopting advanced rotor and stator parameter design, low starting pressure, high efficiency and good retention.

• High working pressure and large output torque. The tapered roller bearing structure is adopted, which has strong bearing capacity of shaft and radial load, so that the motor can directly drive the working mechanism, for a wider range of applications.

• The disk distribution structure makes the motor distribution accuracy high, and the automatic compensation ability after wear is strong, ensuring high volumetric efficiency and long motor life, ensuring stable motor speed and stable load speed characteristics
