Our GN series radial piston hydraulic motor can replace SAI GM hydraulic motor

Our low speed hydraulic motor can up to 12500ml/r

Our GN series motors are a result of many years experice based on Italy technology.our radial piston hydraulic motors have high continious power rating and ,both because of the reducsed ibternal specific load,but aso the high machenical and volumetic efficiency that contributr in reducing the the amount of heat produced and thearfore the negative the effects associated with it.

Feathures

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 transferring between the
piston and the crankshaft through rolling bearing,so the friction loss during the transferring process of force is reduced. Therefore, GN   series hydraulic motor has such
features as: very high mechanical ef? ciency and comparatively high startup torque(mechanical ef? ciency 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 ef? ciency(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 1r/
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 spesi? c 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 transmi
ssion shaft allows endure radial load and the rotational direction is reversible.
