Scorpion HK2221 Bearing Kit : SC-HK2221BEARINGKIT

In order to keep your motor in top running condition, you need a good set of bearings. Occasionally, after a crash or landing in the dirt, the bearings can become damaged and need to be replaced. The Scorpion HK-22 Motor Bearing Kit includes a pair of original equipment replacement bearings to fit the later series Scorpion HK-2208, HK-2213, HK-2216 and HK-2221 Series motors (except HK-2206 series).

There are two bearings in the kit. The first measure 8mm OD x 4mm ID x 3mm thick, And the second measures 11mm OD x 4mm ID x 4mm thick, and are an exact replacement for the stock bearings that come with the motors.

Please note, the bearings are an exact fit into the motor housings, so they do fit snugly. When removing the old bearings, you may need to gently tap them out. However, when installing the new bearings, do not tap them in with anything, as this can dent the ball races and ruin the bearings. When installing ball bearings they need to be pressed in by the outer part of the race. Never apply pressure to the inner race, as this can damage the bearing and lead to premature failure.
