Hydraulic Motors
QJM Series Radial Ball-Piston Hydraulic Motors
QJM Series low-speed high-torque radial ball-piston hydraulic motors use a floating-rotor structure for heavy rotary, winch, marine, mining and industrial drives.
- Selection focus
- Fixed or two-speed operation, structural option and duty confirmation
- Typical applications
- Mining, hoisting, rotary equipment, industrial drives

Technical selection reference
Series reference
