HK-40 Outrunner Bearing Set SPSHK40BK for Scorpion Motors  [SPSHK40BK]

Service Bearings for HK-40 Outrunner Motors

This spare bearing set fits Scorpion HK-40 series outrunner RC motors and is supplied as a maintenance item to replace worn bearing components. The kit concentrates on the bearings that stabilise the motor shaft and cut rotational friction in small-scale outrunner units.

Compatibility note: intended for use with HK-40 family motors; verify the bearing seat diameter and shaft journal before fitting. Avoid guessing fitment across other motor lines without measurement confirmation.

Fitting guidance: disassemble the motor endbell or rotor assembly per the motor's service instructions, remove the old bearings carefully, and press the new bearings into place ensuring even seating and avoiding pressure on the inner race. Reassemble and verify smooth rotation and minimal axial play prior to reuse.

Why replace bearings: worn bearings increase heat and reduce RPM consistency; replacing them supports reliable motor performance and keeps HK-40 outrunners running cleanly for regular RC operation. Schedule inspections and replace bearings as wear appears.
