7075 Aluminium BB DJC Sleeve for RC Bearings - Arrowmax AM-010080  [AM-010080]

Durable BB DJC sleeve for drivetrain and hubs

The Arrowmax AM-010080 BB DJC Sleeve is an RC-scale component manufactured from 7075 aluminium to pair with BB DJC bearing assemblies. It works as an internal sleeve that helps secure bearing alignment and keeps bearing elements contacting correctly while performing drivetrain or wheel hub maintenance.

In service it acts as a changeable wear surface inside BB DJC assemblies, helping to limit play and maintain bearing seat geometry after repeated maintenance cycles or part changes. The part is intended for routine model-level upkeep and should be replaced if wear alters seating.

Notes on installation and setup: the sleeve fits into the BB DJC assembly and influences both axial and radial alignment of the bearing stack; verify seating and clearance with your current BB DJC setup to maintain intended alignment and reduce runout risks.
