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 S-30 Motor Bearing Kit includes a set of three original equipment replacement bearings to fit all of the Scorpion S-30 Series motors, except S-3032 Series motors.
The S-30 Motor Bearing Kit contains three bearings, the rear bearing measures 10mm OD x 5mm ID x 4mm thick and the front bearings measure 8mm OD x 5mm ID x 2.5mm thick. These bearings are exact replacements 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.
