The NAM series crankshaft connecting rod type low speed high torque hydraulic motor is produced
according to Italian standards but in consideration of actual situations of China.The main parts and components
are machined by machining center and CNC machine tools.All the seal parts and high strength interior hexagonal
bolts are imported from Germany, Italia and Taiwan. The casting is made of polyester sand nodular cast iron to
ensure the performance and appearance quality of the products to overpass the similar products in China and
overseas market.
The product has the following features:
(1) As the product adopts eccentric crankshaft and five-piston structure
with comparatively low frequency, it has low noise characteristic.
(2) It has big startup torque, perfect stability at low speed, so it can
stably operate at very low speed;
(3) 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;
(4) The crankshaft and the connecting rod are supported by roller, so it
has very high mechanical efficiency;
(5) The rotational direction is reversible, the output shaft allows endure
certain radial and axial force;
(6) It has comparatively high power mass ratio
