BlackBearing Bushing Bosch Axle Gen4
Description
This bushing is designed to be installed on the crankset axle of the Gen 4 Bosch motor.
It is strongly recommended replacing both bushings per motor for optimal performance.
When the friction bushings wear out, play may develop in the crankset axle, even after replacing the bearings included in the EM-026-BOSCH service kit (or with individual bearing replacements). As this part is not sold separately by Bosch, their official recommendation is to replace the entire motor unit when axle play occurs.
