Hydraulic Orbital, Geroler and Gerotor Motors

Hydraulic orbital motors are low-speed, high-torque hydraulic motors used in agricultural machinery, construction equipment, industrial machinery and mobile equipment. They are also commonly referred to as gerotor motors or Geroler motors, depending on the internal design used to generate torque and rotation.

Technical Union offers hydraulic orbital motors for applications requiring a combination of high torque, low speed, reversible operation and reliable performance. Different motor series are available to meet the displacement, pressure, speed and configuration requirements of each hydraulic system.

Geroler and Gerotor Motors

The terms Geroler and Gerotor are commonly used to identify different designs of hydraulic orbital motors. Geroler motors use a rotor and roller assembly designed to provide efficient operation at low speed and high torque.

Customers may search for these motors using terms such as Geroler hydraulic motor, Geroler motor, orbital Geroler motor, Gerotor motor, hydraulic Gerotor motor, and Geroler motors. Depending on the application, we can help identify the appropriate hydraulic motor based on displacement, torque, pressure, RPM, mounting configuration, shaft and hydraulic connections.

Replacement Motors for Char-Lynn, Eaton, Danfoss, Parker and White

When replacing an existing hydraulic motor, customers often search by the brand and part number of the original motor. Technical Union can help identify cross-over and replacement options for applications currently using motors from brands such as Char-Lynn, Eaton, Danfoss, Parker, White and M+S.

Common searches include Char-Lynn motor, Char-Lynn hydraulic motor, Eaton Char-Lynn motor, Eaton hydraulic motor, Danfoss hydraulic motor, Danfoss Geroler motor, Parker hydraulic motor, Parker Gerotor motor, White hydraulic motor and White Gerotor motor.

Motor compatibility should be verified based on the technical requirements of the application. When selecting a replacement, important specifications may include displacement, continuous and peak pressure, torque, operating speed, mounting, shaft configuration, hydraulic ports and overall dimensions.

Applications for Hydraulic Orbital Motors

Hydraulic orbital motors are used in many applications where direct hydraulic rotary power is required. Common applications include:

• Agricultural machinery and harvesting equipment
• Tractors and agricultural implements
• Conveyors and drive systems
• Winches and traction equipment
• Sweepers and municipal equipment
• Construction machinery
• Loaders and mobile equipment
• Forestry equipment
• Industrial machinery
• Hydraulic drive systems
• Drilling and material-handling equipment
• Applications requiring high torque at low speed

Selecting a Hydraulic Orbital Motor

Selecting the correct orbital motor requires understanding the requirements of the application. Important parameters include required torque, hydraulic pressure, flow rate, operating RPM, displacement and direction of rotation.

Mechanical and installation requirements should also be verified, including the mounting configuration, shaft type, hydraulic connections and overall dimensions.

Hydraulic Motor Cross-Over and Replacement

If you need to replace an existing Char-Lynn, Eaton, Danfoss, Parker, White, M+S or other hydraulic motor, you do not necessarily need to know all of the motor specifications.

Send us the part number of the motor you are currently using, and our team can perform a cross-over (equivalency) review to help identify a suitable replacement. You can also send us a photo of the motor or identification plate, along with any available information about the application.

We can help identify replacement options for existing Geroler, Gerotor and orbital hydraulic motors and verify the important technical characteristics before quotation.

Request a quotation for hydraulic orbital motors by providing the existing motor part number, a photo of the motor or identification plate, or the available application specifications. Our team can help identify the appropriate motor and review a compatible replacement or cross-over for your application.
