QJM variable ball piston motor

1. Light weight,small size2. Wide speed regulating range3. Reliable performance and long life

4. Capable of stepping variation

5. Widely applied for mine engineering,hoisting rtansport,metallurgy,ships,machine tools,plastics processing and geological prospecting , etc.

6. Because the rolling body of this motor is replaced by a steel ball rather than two more rollers and beams commonly used in inner curve hydraulic motors ,it is simple in structure ,reliable in performance and greatly reduced in volume or weight

7. A small kinematic pair inertia and a hard steel ball make this motor continuously work during the rotation at higher speed and under stronger impact load

8.  It has higher mechanical and volumertic efficiency for its small friction pair ,oil feed shaft balanced with roller ,piston pair capable of static pressure balance and good lubrication and coated high pressure sealing oil on soft plastic mat.

9. As the oil feed shaft and stator are in rigid connection ,the oil pipeline of this model can be connected with steel pipe

10. As this model has variable displacements dual and trinal speeds ,it is wider in speed regulating range.

11. Simple structure and easy maintenance12. The output shaft of the standard model can only endure the torque rather than outside radial and axial forces ,while that one of Z series hydraulic motor can endure outside radial and exial forces

13. As T series hydraulic motor has a central through hole ,the rotating shaft can pass through the motor

14. Very competitive price

15. 1 year of warranty
