We are a professional manufacturer of NHM31 Series Hydraulic Motor

NAM series bent axle connecting rod type motor has such characteristics as: high mechanical efficiency and good reliability, 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.

Features:
As the product adopts eccentric crankshaft and five-piston structure with comparatively low frequency, it has low noise characteristic;
It has big startup torque, perfect stability at low speed, so it can stably operate at very low speed.
The patented plane compensation port plate has perfect reliability and almost no leakage. The piston bushing is sealed by seal ring, so it has comparatively high volume efficiency.
The crankshaft and the connecting rod are supported by roller, so it has very high mechanical efficiency;
The rotational direction is reversible, the output shaft allows endure certain radial and axial force;
It has comparatively high power mass ratio.
