Orbital Motor OMR 250


The OMR 250 is an orbital motor, designed to convert hydraulic fluid power into rotary motion (shaft rotation). It's likely used in various mobile and industrial applications requiring precise control of speed and torque. Here's a breakdown of what we know about OMR 250 motors




OMR 250 likely refers to a specific model of orbital motor manufactured by several companies

An inner, oval-shaped gear (rotor)

An outer gear with matching teeth (stator)

Hydraulic fluid flows through the motor, exerting pressure on the rotor's teeth, causing it to rotate around the stator.

The unique shape of the rotor and stator creates a continuous pressurized pocket of fluid that pushes the rotor, generating torque.

By controlling the flow and pressure of the hydraulic fluid, the speed and direction of the OMR 250's shaft rotation can be precisely regulated.



Due to their ability to deliver high torque at low speeds and a larger size compared to OMR 50 or 80 variants, OMR 250 motors are suitable for applications requiring more power, such as


Construction Equipment

Driving wheels (for locomotion) in medium-sized excavators, backhoes, or loaders.

Swing drives (rotating the upper body) in excavators.

Powering attachments (like forestry mulchers or large trenchers) on skid steer loaders or tractors.

Tilting buckets or blades on medium-sized construction machinery.

Agricultural Machinery

Powering wheels on large tractors or harvesters.

Operating high-power post drivers or rock drills.

Driving conveyor belts for moving substantial quantities of crops or materials.

Industrial Automation

Conveyor belt drives in heavy-duty assembly lines handling large or heavy objects.

Industrial mixers or shakers with high torque requirements.

Operating wind turbine yaw drives (rotating the nacelle).

Specifications (Examples)


Displacement OMR 250 motors likely have a displacement around 250 ccrev (cubic centimeters per revolution), indicating the volume of fluid delivered per revolution of the shaft. This is a typical estimate, and the exact displacement can vary depending on the manufacturer's model.

Pressure The maximum operating pressure may vary depending on the specific manufacturer's model, but it typically ranges from 140 to 225 bar (around 2000 to 3200 psi) for OMR motors in general.

Torque OMR 250 motors can generate higher torque compared to OMR 50 or 80 variants, making them suitable for demanding applications requiring more power.

Important Note


The specific features, applications, displacement, pressure rating, torque output, and recommended applications of the OMR 250 can vary depending on the manufacturer's model.

If you have a specific OMR 250 motor, it's crucial to refer to the manufacturer's specifications or datasheet for accurate information.

Finding More Information About Your OMR 250


Look for a part number The motor itself might have a part number that can help identify the manufacturer and specific model.

Consult the user manual or parts catalog for your equipment. It should specify the model and function of the OMR 250 motor.

Contact a hydraulics specialist HANJIU . They can provide detailed information based on the specific model and manufacturer.

I hope this comprehensive explanation clarifies the OMR 250 orbital motor and its applications. Feel free to ask if you have any further questions!
