STEEL BEARING 14x25,4x6 "HS" REAR MOTOR (UR, OS) (1)

This is a "High Speed" or "HS" Rear Bearing from Ultimate Racing. This bearing has been designed for the Ultimate M-3 engines but can also be used in any .21 engine that uses bearings of these sizes. The bearing measurements are 14mm inside, 25.4mm outside and 6mm wide.

This bearing should be installed with the balls towards the rear of the motor (towards the crankcase lid) for better lubrication.
