Hydraulic Motors – Orbital, Gear & Piston Motors

Patriot Hydraulics stocks a broad range of hydraulic motors for continuous rotation applications in mobile equipment, agriculture, construction, and industrial machinery. Choose from orbital (Gerotor), gear, and high-speed piston motors to match your torque, speed, and mounting requirements.

Orbital / Gerotor Hydraulic Motors

Orbital hydraulic motors (also called Geroler or Gerotor motors) deliver high torque at low RPM — ideal for conveyor drives, auger motors, wheel motors on compact equipment, and fan drives. Available in SAE A, B, and C mount configurations with displacement from 6 to 800+ cc/rev.
