Outrunner Bearings for SII-22 Motors - Scorpion SPS22BK  [SPS22BK]

Outrunner bearings tailored to SII-22

This Scorpion SPS22BK bearing kit is intended as a replacement bearing set for SII-22 series outrunner motors used in RC models. It targets noisy or loose bearings to restore consistent rotor alignment, reduce friction, and improve running smoothness.

Compatibility is limited to the SII-22 family of outrunner motors; apply this kit when you detect grinding, rough rotation, excessive play, or elevated motor temperature in normal operation. Bearing replacement is a standard maintenance step that helps retain motor efficiency and predictable power under load.

For installation, remove the motor from the model, dismantle the endbell and rotor to reach the bearings, extract the worn bearings carefully, press the new bearings fully into the housing ensuring correct seating and shaft concentricity, then reassemble and check for free rotation before refitting the motor. After fitting, run the motor at modest load to confirm noise has dropped and the temperature is stable.
