HK-40 Bearing Kit SPSHK40BK Replacement for Scorpion Outrunners  [SPSHK40BK]

HK-40 Bearing Upgrade Pack

This bearing kit is supplied for Scorpion HK-40 series outrunner RC motors as a direct replacement option to restore bearing function during standard maintenance. The set targets the bearings that stabilise the motor shaft and cut down rotational friction common in outrunner motors used in RC models.

Compatibility reminder: the kit is intended for HK-40 series motors; always verify bearing seat and shaft dimensions to ensure correct fitment before installing replacements. Avoid fitting without confirming dimensions across different motor families.

Service procedure: follow your motor's disassembly steps to remove the endbell or rotor, extract the worn bearings carefully, then press in the replacement bearings ensuring they sit squarely and that pressure is not applied through the inner race only. Reassemble and test for smooth spin and minimal axial movement before returning the motor to use.

Performance impact: replacing worn bearings reduces friction and heat, improving RPM consistency and overall reliability of HK-40 outrunner motors when inspected and serviced at regular intervals.
