Scorpion SPS22BK Outrunner Motor Bearing Kit  [SPS22BK]

SII-22 outrunner bearing kit

This Scorpion SPS22BK bearing kit is intended as a replacement bearing set for SII-22 series outrunner motors used in RC models. It targets routine motor upkeep where worn or noisy bearings affect smooth rotation and thermal behavior, restoring consistent rotor alignment and reducing unwanted friction in the motor assembly.

Compatibility is limited to the SII-22 family of outrunner motors; use this kit when bearings exhibit grinding, roughness, excessive play, or elevated motor temperature during normal operation. Replacing bearings is a maintenance task that preserves motor efficiency and helps maintain predictable power delivery under load.

For installation, remove the motor from the model, disassemble the endbell and rotor to access the bearings, extract the aged bearings carefully, press the replacements fully into the housing ensuring correct seating and shaft concentricity, then reassemble and verify free rotation before reinstalling the motor. After replacement, run the motor with moderate load to confirm noise reduction and stable temperature.
