Gerotor & Geroler

Incredible Amount of Torque When You Need It.

Both the Gerotor and Geroler hydraulic motors proved an incredible amount of torque.

Gerotor Motor – When There Is a Need for a Significant Amount of Torque.

This type of motor is used in applications which require a large amount of torque in an unfavorable environment. The Gerotor, also known as a type of orbital motor, has very few moving parts when compared to an axial or radial piston hydraulic motor.

Gerotor motors are classified as LSHT motor or low-speed high-torque hydraulic motors. While the motor is running at high speeds, Gerotor motors generate the torque needed for traction-intensive applications found in the construction, agricultural, and forestry industry.

Vehicle Propulsion Systems

Hydraulic motors are often used to drive off-highway vehicles, either directly or through gear reducers. The power required to propel the vehicle, called “Tractive Effort,” is supplied by the hydraulic motor(s). It is normally expressed in pounds and is the sum of the forces (Parker LSHT Torqmotors and Nichols Motors™ Engineering Data).

Geroler Motor – When It Comes to Performance, the Geroler Motor Outperforms the Gerotor Motor.

Geroler motors are very similar to Gerotor motors with one major difference. The Gerolor has rolls added to the outer gear ring. These so-called rolls act as bearings to reduce friction, decrease wear, increase efficiency, and allow for a much smoother operation.
