Shandong Rnomac Hydraulic Machinery Co.,Ltd

we are offering hydraulic orbital motor for crane. bm1 series orbital hydraulic motor description and features bm1 series motors are small volume spool valve orbit motor with the following features: 1.advanced design of spool valve and stator&rotor, small size and compact structure. 2.credible design of shaft seal, which can bear high pressure and be used in parallel or in series. 3.direction of shaft rotation and speed can be controlled easily and smoothly. 4.high efficiency and economical, suitable for medium duty applications. 5.a variety of connection types of flange, output shaft and oil port.

We are offering double shaft orbit motor.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 torque2. Wide speed range, non-grade adjustment of speed, minimum steady speed is 15rpm, easy and convenient to be equipped with, low cost3. Used in series and in parallel way of a hydraulic systemlittle inertia of rotary, easily to be started, can rotate clockwise and counterclockwise, dont stop rotating when change directionmain function features:1. Shaft groove distributes flow, simple and compact structure, high accuracy of flow distributing2. Stator-rotor in toothed shape, high mechanical efficiency, longer working lifetime under high pressure3. Touching-ball bearing of coupled-angle, can bear higher loading in radial and axial direction, low friction force, high mechanical efficiency.
