Radial Piston Motors

Radial piston motors are known for their exceptional efficiency, long service life, and ability to deliver high torque at low speeds. Thanks to their precision engineering, they offer excellent low-speed performance with minimal energy loss — often eliminating the need for a gearbox.

Key Applications

Ideal for demanding, low-speed, high-torque tasks such as:

Winch drives | Concrete mixers | Marine trawlers | Plastic injection moulding machines

Motor Designs

Crankshaft Type

• Features inward-pushing pistons on a single cam
• Delivers extremely high starting torque
• Displacements range from 40cc/rev to 12L/rev
• Capable of “creep” speeds and up to 1500 rpm with near-constant torque
• Versatile and reliable, even in legacy systems

Multilobe Cam Ring Type

• Uses outward-pushing piston rollers on a multi-lobed cam ring
• Produces smooth output and high torque at low speeds
• Available from 1L/rev to 250L/rev
• Ideal for high-power, low-speed applications

🔧 Variants Available

We supply a wide range of radial piston motor types, including:

Compact | Fixed or dual displacement | Low speed high torque (LSHT) | Two-speed and variable displacement options
