Danfoss Orbital Motors
Danfoss orbital motors for conveyor, auger, winch and steering drives, quoted from the nameplate code that encodes displacement and porting.

Request a QuoteOrbital motors are low-speed, high-torque hydraulic motors built around a gerotor or geroler element, and they are the standard drive for conveyors, augers, winches and steering on mobile and industrial machines. They fail on shaft seals and on the internal wear pair, usually after contamination has been through the circuit.
The code number on the nameplate encodes displacement, shaft type, port configuration and options in a single string, which is why a visually identical motor can be functionally wrong. Send the code exactly as printed.
Give us the code number, or the displacement, shaft, porting and mounting, and we will quote the motor or the seal kit.

Danfoss Orbital Motors: Common Questions
The code number stamped on the motor. It encodes displacement, shaft type and size, port configuration, mounting flange and options in one string, so it is the whole specification. If the nameplate is unreadable, send displacement, shaft, porting and mounting instead.
Yes. Shaft seal failure is the usual first symptom and a kit costs a fraction of a motor, so it is worth checking the fluid before assuming the motor is finished. Send the motor code and we will quote the kit.
They are different displacement and torque classes in the same orbital family. OMP and OMR cover light to medium duty and OMH sits above them, with OMS and OMT higher again. Tell us the duty and we will confirm which fits.
Usually. Send the old code and what the motor drives. Where a series has been superseded we identify the current equivalent rather than quote a number that no longer ships.
Yes, including seal kits and wear pairs. Send the code number and tell us which part failed.
