Hydraulic Gear Motor, CMK1 Series

Hydraulic Motor, Hydraulic System, Hydraulic Motor for Crane, Hydraulic Motor for Excavator, Hydraulic Drive System

CMK1 series hydraulic gear motor is an actuating component in hydraulic system, incorporating high-strength aluminum alloy housings and DU bearings with high loading capacity. It features high pressure, wide speed range, various displacement options, simple structure, reliable performance and easy maintenance. CMK1 series hydraulic motor can rotate for single-direction or dual-direction. In the case of one-direction rotation, safety valve is available for option.

Hydraulic systems for engineering machinery, mining machinery, lifting machinery, and transportation machinery, etc.

1. The hydraulic gear motor is equipped with imported oil seal, combined seal, and whole bushing. It is excellent for beautiful exterior, small starting torque (≤2.5NM), high impact resistance, high efficiency (92%), low noise, and high working pressure.
The air conditioning/fan motor series employs driving gear and shaft broken structure. It is capable of bearing a certain range of radial force and axial force. The oil seal is imported from reliable supplier. The max allowable pressure the motor is able to bear is 1MPa. Combined (PTFE + rubber) seal structure is adopted for W ring to reduce the start torque and to improve the assembly pass rate.
