We produce GM2 Series Piston Hydraulic Motor based on the technology of ITALY SAI GM series hydraulic motor but with some improvement. It can be completely interchanged with SAI motor on performance and dimensions but with low cost and fast delivery. It features for high mechanical efficiency, high torque and small volume.
This GM2 Series Piston Hydraulic Motor has such characteristics as: high mechanical efficiency and small volume, thus it can be widely applied in hydraulic and transmission systems of plastics machinery, light industrial machinery, heavy type metallurgical machinery, petroleum and coal mining machinery, lifting and transportation equipment, ship’s deck machinery, geological prospecting equipments, etc.
1. High Efficiency, small volume, light weight
2.High starting torque, high specific speed range
3.Motor can be used in the pump working condition and realize freewheel operation condition.
4. Compact structure, reasonable design
5. Adopting high load capacity bearing and output shaft which can bear radial load and reverse the direction of rotation.
6. The mounting dimension and more than 80% of internal components can be interchanged with SAI GM2 Series Piston Hydraulic Motor.
