Kawasaki Staffa SX510 heavy-duty, high-torque radial piston hydraulic motor
Kawasaki Staffa SX510 heavy-duty, high-torque radial piston hydraulic motor
The Kawasaki Staffa SX510 (SX510BM) is a heavy-duty high-torque, low-speed (HTLS / LSHT) radial piston hydraulic motor, engineered for extreme load applications requiring massive torque at very low rotational speeds.
The SX series is famous for its “Five-Star” radial design, clearly visible as five separate cylinder housings, delivering superior load distribution, smooth rotation, and exceptional durability in continuous duty environments.
This motor is widely used in marine, offshore, construction, and heavy industrial machinery where reliability and long service life are critical.
