Gear motors from Guorui Hydraulics have a floating bushing feature with automatic axial clearance compensation. The bushings are made with special abrasion resistant material providing improved service life. Precisely machined gears ensure the excellent characteristics under low noise condition. Our cold extrusion motor bodies can endure pressure above 30 MPa. High strength cast iron front & rear covers also enhance our reliability. Our gear motors are widely used in the industrial, mobile, marine and aerospace industries.
