Orbital Motor OMR 315


The OMR 315 is an orbital motor, designed for use in hydraulic systems. It converts the energy of pressurized hydraulic fluid into rotary motion (shaft rotation). Here's a breakdown of what we know about OMR 315 motors




OMR 315 likely refers to a specific model of orbital motor manufactured by several companies

As with most orbital motors, the OMR 315 likely uses a gerotor design. This design involves two key components

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 315's shaft rotation can be precisely controlled.



Due to their ability to deliver high torque at low speeds and a larger size compared to smaller OMR variants, OMR 315 motors are suitable for applications requiring significant power, such as


Construction Equipment

Driving wheels (for locomotion) in larger excavators, backhoes, or loaders.

Swing drives (rotating the upper body) in excavators.

Powering high-demand attachments (like large forestry chippers, industrial shredders, or pile drivers) on skid steer loaders or tractors.

Tilting buckets or blades on large construction machinery.

Agricultural Machinery

Powering wheels on large tractors or harvesters used for demanding tasks.

Operating high-power equipment like sugar cane harvesters or tree planters.

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

Industrial Automation

Conveyor belt drives in heavy-duty industrial settings handling very large or heavy objects.

Industrial mixers or shakers with extremely high torque requirements in processes like concrete mixing or metal recycling.

Operating wind turbine yaw drives (rotating the nacelle) in large turbines.

Specifications (Examples)


Displacement OMR 315 motors likely have a displacement around 315 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 315 motors can generate high torque, suitable for demanding applications requiring significant power.

Important Note


The specific features, applications, displacement, pressure rating, torque output, and recommended applications of the OMR 315 can vary depending on the manufacturer's model.

If you have a specific OMR 315 motor, it's crucial to refer to the manufacturer's specifications or datasheet for accurate information about its capabilities and limitations.

Finding More Information About Your OMR 315


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 315 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 315 orbital motor and its applications. Feel free to ask if you have any further questions!
