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.

ThreadFit 30 bottom bracket is silky smooth and long-lasting thanks to legendary, angular-contact bearings. They actually get faster over time as their contact surfaces wear, because they are build to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect, and precise fit between cranks and frame. That’s where the low drag and butter smooth feel come from.
