HMr Series 50/63/80/100/125/160/200/250/315/400/500 Orbital Hydraulic Motor | Low Speed High Torque | Durable
The HMr series hydraulic motor is a low-speed high-torque orbital hydraulic motor featuring a shaft distribution design and integrated stator-rotor pair, efficiently converting hydraulic energy into mechanical energy. It boasts compact size, light weight, low starting pressure, and smooth low-speed operation, supporting a wide speed range of 10-775 r/min and working pressure of 14-17.5 MPa. Widely used in rotary mechanisms of injection molding machines, road sweepers, lawn mowers, conveyors, harvesters, and cranes, it allows series/parallel installation and serves as a cost-effective alternative to imported motors.
