This is a Scorpion HK-45 V2 Motor Bearing Kit. The Scorpion HK-45mm Motor Bearing Kit includes a pair of direct replacement bearings to fit the Scorpion HK-4525 Series motors. In order to keep your motor in top running condition, you need to keep the bearings running smooth. The bearings can sometimes become damaged and need replacement after a crash, or hard landing in the dirt. These bearings have a 19mm OD, 10mm ID, and are 5mm thick, and are an exact replacement for the stock bearings that come with the motors.
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.
