Arrowmax AM-010080 BB DJC Sleeve (7075)  [AM-010080]

BB DJC Sleeve for RC drivetrains

This Arrowmax AM-010080 BB DJC Sleeve is an RC-scale accessory designed to work with BB DJC bearing assemblies, manufactured from 7075 aluminum for consistent dimensional stability. It serves as an internal sleeve that supports bearing alignment and helps maintain consistent contact between bearing components during drivetrain and wheel hub servicing.

In practical use it functions as a replaceable wear surface within BB DJC assemblies, aiding in reducing play and preserving the bearing seat geometry after repeated maintenance or component swaps. The part is intended for model-level setups and should be integrated as part of routine drivetrain or wheel hub maintenance.

Installation and tuning role notes: the sleeve is positioned inside the BB DJC assembly and participates in axial and radial alignment of the bearing stack; when fitting, verify clearance and seating within your existing BB DJC arrangement to retain intended alignment and minimize runout.
