In order to keep your motor in top running condition, you need a good set of bearings. The Scorpion 40mm Motor Bearing Kit includes a set of three original equipment replacement bearings to fit all of the Scorpion 40mm S-Series motors.
The 40mm Bearing Kit contains three bearings, one for the rear side and two for the front side of the motor. The rear bearing measures 13mm OD x 6mm ID x 5mm thick, and the front bearings measure 10mm OD x 6mm ID x 3mm thick. These bearings are exact replacements for the stock bearings that come with the motors.
