BB DJC Sleeve 7075 Aluminium Performance Insert - Arrowmax AM-010080  [AM-010080]

Performance insert for BB DJC bearing assemblies

The Arrowmax AM-010080 BB DJC Sleeve is a precision RC-scale insert designed for BB DJC bearing assemblies and machined from 7075 aluminium for dimensional stability. The sleeve is an inner component that supports correct bearing alignment and maintains consistent contact between bearing elements during drivetrain and wheel hub maintenance.

Serving as a replaceable wear insert, the sleeve helps reduce play and preserves the original bearing seat geometry after servicing or component swaps. It is intended for model-level maintenance and should be incorporated into routine checks of drivetrains and hubs.

Fitting guidance: the sleeve is placed inside the BB DJC assembly where it helps control axial and radial alignment of the bearing stack. When fitting, confirm the sleeve seats correctly and that bearing clearance mirrors the original configuration to avoid introducing runout.
