Axial, Radial, and Bent Axis Piston Motors

Our selection of hydraulic piston motors is engineered for reliable performance across a wide range of mobile and industrial applications.

  • Axial piston motors: Feature pistons aligned with the drive shaft, delivering high speeds in a compact footprint.
  • Radial piston motors: Have pistons arranged around the shaft, ideal for producing high torque at lower speeds.
  • Bent axis motors: Offer efficient operation in systems requiring alignment flexibility or space-saving configurations.

Our available models include displacements up to 2.48 cu in/rev, pressure ratings up to 3000 PSI, and speeds up to 3600 RPM. Trusted brands like Danfoss ensure long-lasting durability and easy integration with hydraulic systems.

Built for Demanding Equipment Industries

Piston motors are essential in hydraulic systems that require efficient, continuous-duty performance. Common applications include:

Many motors include SAE-standard flanges, side ports, and case drain configurations. Select models also support closed-loop hydraulic motor circuits and through-drive installations.

How to Choose the Right Hydraulic Piston Motor

Choosing the right piston hydraulic motor depends on several key factors:

  • Required torque and operating speed
  • System pressure and flow capacity
  • Fixed displacement requirements
  • Shaft style: splined, keyed, or tapered
  • Mounting type and available space
  • Port orientation and case drain configuration

Most motors in our selection are fixed displacement, meaning they deliver a constant output for consistent system performance. These are ideal for applications where reliable torque and speed are required without variable control.

Piston Motor FAQs

What is a piston motor used for?

Piston motors power hydraulic systems that require high torque and smooth, controlled motion. They’re used in construction, agriculture, marine, and industrial applications.

What’s the difference between axial and radial piston motors?

Axial piston motors are compact and well-suited for high-speed systems. Radial motors generate more torque at lower speeds, making them ideal for heavy-duty or slow-moving equipment.

How does a hydraulic piston motor work?

Hydraulic fluid enters the motor and pushes pistons in a circular pattern, converting fluid energy into mechanical rotation. The arrangement of the pistons determines the motor type and torque characteristics.

What’s the difference between a piston motor and a gear motor?

Piston motors deliver higher torque and better efficiency at low speeds, while gear motors are simpler and better for lighter-duty, cost-sensitive applications.
