SII-22 Outrunner Bearing Replacement Kit - Scorpion SPS22BK  [SPS22BK]

Replacement bearings for SII-22 outrunners

This Scorpion SPS22BK bearing kit is supplied as a replacement set for SII-22 series outrunner motors used in RC models. It is intended to bring back steady rotor alignment, reduce internal friction, and cut down on vibration and noise that indicate worn bearings.

Use this kit specifically for SII-22 family outrunner motors when you notice grinding, rough rotation, excess radial or axial play, or an abnormal rise in motor operating temperature. Replacing worn bearings helps retain motor efficiency and preserves predictable power delivery under load.

For a smooth installation, remove the motor from the model, take apart the endbell and rotor to access the old bearings, carefully press out the used bearings and press the new bearings fully into position ensuring correct seating and shaft concentricity, then reassemble and check free rotation before reinstalling. After replacement, run the motor at moderate load to confirm reduced noise and a stable temperature.
