This Bosch O-ring 36x1.5 mm provides the sealing function between the pinion nut and the motor housing, preventing fluid ingress and contamination of the gears. It is specifically sized for BDU2XX drivetrains and derivatives.
Made from elastomeric, abrasion-resistant materials that withstand temperature variations, this O-ring offers good mechanical and chemical resistance for extended use on urban e-bikes.
Designed for Bosch eBike systems (BES2 / Smart System) and compatible with models BDU250C / 255C / 250P / 250P CX / 290P, it is suitable for city bike applications and maintenance or OEM replacement.
The O-ring is easy to fit onto the pinion nut thanks to its precise dimensions (36x1.5 mm), ensuring a snug fit. No special maintenance is required other than a visual check during motor service.
