MCRO3/MCR05 Hydraulic Motor OVERVIEW

MCR03 and MCR05 are multi-stroke radial piston low-speed high-torque hydraulic motors, fully interchangeable with Bosch Rexroth original series. Adopting roller-cam and disc valve distribution structure, they feature high pressure resistance, strong load capacity and stable ultra-low speed operation. Optional integrated brake and two-speed displacement structure make them widely used as wheel drive and rotary drive for heavy mobile machinery. Our aftermarket motors support OEM customization to meet diverse equipment matching demands.
