supply orbital hydraulic motor BM4 series

详情

BM4 series orbital hydraulic motor is a small motor of low speed, high torque, with a stator-rotor package in toothed shape.
Advantage:
1. Small, lightweight, smaller than other hydraulic motor of the same torque
2. Wide speed range, non-grade adjustment of speed, minimum steady speed is *5rpm, easy and convenient to be equipped with, low cost
3. Used in series and in parallel way of a hydraulic system
little inertia of rotary, easily to be started, can rotate clockwise and counterclockwise, don’t stop rotating when change direction
Main function features:
1. Shaft groove distributes flow, simple and compact structure, high accuracy of flow distributing
2. Stator-rotor in toothed shape, high mechanical efficiency, longer working lifetime under high pressure
3. Touching-ball bearing of coupled-angle, can bear higher loading in radial and axial direction, low friction force, high mechanical efficiency.
