GM series hydraulic motors, which are also called radial piston hydraulic motors, are a result of many years of experience based on Italy technology. It incorporates a number of design variations with respect to many series intended to increase the strength of the motor casings and the load capacity of the internal dynamic components.

Features 1. High mechanical efficiency, high starting torque GM Series motors reduce friction loss in force transmission because of no side force between piston and swing cylinder, hydrostatic balance designed in piston foot and transferring torque force through roller bearing. Therefore, GM series hydraulic motors have high mechanical efficiency and high starting torque (above 0.92).

 2. High volumetric efficiency The flat distributor is simple, reliable and good seal and theres no leakage between piston and swing cylinder through using plastic seal ring, so motors have high volumetric efficiency.

3. High specific speed range Because of reducing friction loss in configuration and improving seal ability, these motors can run steadily in 1 r/min condition. Moreover, theres no gap between piston and bearing cover connected by ring clip, so they can run with high speed when inlet is sealed and the ratio (max speed) is higher than any other type of equivalent hydraulic motor, giving greater flexibility of application.

4. Minimize heat generation, due to the reduced friction area.

5. Low noise, high lifetime, high power and high external loads. These series motors have high pressure, with the Max pressure 45Mpa, light weight, small volume, high power; Using high loaded bearing, so they have reliable performance, long life, low noise and transmission shaft can bear radial load and rotate in opposite direction.
