Product overview

The Scorpion HK-2520 Motor Bearing Kit provides two original equipment replacement bearings for servicing the Scorpion HK-2520 motor. Its purpose is to replace the stock bearings when they become damaged, including damage that can follow a crash or a landing in dirt. The supplied pair contains two different outside diameters: the first bearing measures 9mm outside diameter by 4mm inside diameter by 4mm thick, while the second measures 11mm outside diameter by 4mm inside diameter by 4mm thick.

Integration is within the motor housings, where the replacement bearings have an exact, snug fit. Removing the old bearings may require gentle tapping, but fitting the new ones requires pressure through the outer part of the race. Tapping a new bearing into place can dent its ball races and ruin it; pressure on the inner race can also cause damage and premature failure. The kit weighs 3g including packaging, so that figure represents the packaged kit rather than the installed bearing pair alone.
