BB DJC Bearing Sleeve 7075 Aluminum - Arrowmax AM-010080  [AM-010080]

RC BB DJC Sleeve for drivetrain precision

This Arrowmax AM-010080 BB DJC Sleeve is an RC-scale part made to mate with BB DJC bearing assemblies and machined from 7075 aluminum for stable dimensions. It acts as an internal insert that helps keep bearing stacks aligned and preserves consistent contact between bearing components during drivetrain and wheel hub work.

Used as a replaceable wear surface, the sleeve reduces play and helps maintain the seat geometry of BB DJC assemblies after repeated servicing or component swaps. It is intended for model-level maintenance and should be fitted as part of regular drivetrain or wheel hub care.

Installation and tuning notes: the sleeve locates inside the BB DJC assembly and contributes to axial and radial alignment of the bearing stack; when installing, confirm clearance and seating in your BB DJC arrangement to retain alignment and minimise runout.
