SAI GM Hydraulic Motor

SAI GM Hydraulic Motor Product Introduction

GM series hydraulic motor is a new type of product of our company, which based on years practical experience and designed and improved the original products on the basis of Italian technologies. 

GM hydraulic motor mainly has the following characteristics:

1. As the piston and the tilt cylinder have no side force ,the piston bottom is designed to be static pressure balance. The torsional force is transferrin!l between the piston and the crankshaft through rolling bearing, so the friction loss during the transferring process of force is reduced.

Therefore, GM series hydraulic motor has such features as: very high mechanical efficiency and comparatively high startup torque(mechanical efficiency of over 0.92 during startup).

2. The plane distributor (patented technology)is simple and reliable with perfect seal performance and almost no leakage. The plastic piston ring is used to seal between the piston and the tilt cylinder, so it has very high volumetric efficiency (can be as high as 0.98).

3. As the structure of this product has reduced friction loss and enhanced the seal performance, the product has perfect stability at low speed. It can stably run at 1 r/min working condition and has big speed regulation range.

4. As the piston is jointed closely with bearing bushing without any clearance, this series of hydraulic motor can run at pump working condition.

5. This series of hydraulic motor has high pressure, light weight, small bulk and high spesific power.

6. As this series hydraulic motor has simple structure, reasonable design and adopts bearing with big load ability, it can work reliably and has long life and low noise; the transmission shaft allows endure radial load and the rotational direction is reversible.

Type: GM05, GM1, GM2, GM3, GM4, GM5, GM6, GM7
