Product Description

BM*- BM4 Series orbital hydraulic motors are small volume hydraulic motors with design of spool valve and Geroler element. They have the following product features:
Adopt geroler element, ensuring higher distributing accuracy, mechanical efficiency and longer lift-time under high back pressures anddouble deep groove ball bearings,
BM*- BM6 Series orbital hydraulic motors are the most advanced disc valve orbital hydraulic motors. They have the following product features:Advanced design of disc valve,Rotor in the Geroler element are treated by carbonitriding, obtaining better surface Smoothness and hardness, reducing the rotation friction and improving the volumetric efficiency and machenical efficiency.etc
