Motor Retention Ring — OMA-38

This RC-scale security ring is manufactured to interface with the OMA-38 motor family and functions as a retention part to help stabilise the motor assembly within its housing during fitting and adjustments. It supports a consistent mounting arrangement under operational conditions.

The ring is intended only for OMA-38 motors and assemblies that call for a matched security ring. Confirm the OMA-38 designation on your motor to ensure proper fit and function before installation.

Installation notes: fit the ring as part of final motor mounting to reduce axial motion of the rotating assembly. Verify the fit after initial runs and after any disassembly as part of routine maintenance and tuning of your RC powertrain.

What risk does excessive axial play pose?

Excessive axial movement can affect rotor alignment and long term bearing wear; the ring reduces that movement to help protect the assembly.

How do I confirm this is the right part for my motor?

Check your motor documentation for the OMA-38 designation and compare the required retention ring specification to ensure compatibility.

Any tips for avoiding fitment issues?

Ensure surfaces are clean, confirm dimensional match to the OMA-38 specification, and re-check seating after initial engine runs or service.
