Casquillo distanciador

The spacer sleeve B6-04-054 is used in the BMW 600 together with a deep-groove ball bearing and ensures the correct axial clearance as well as the preload in the axle or hub assembly. During restorations, it is important to inspect used sleeves for wear, corrosion, and dimensional accuracy, as incorrect bearing play can lead to premature wear of the bearings and hubs. If necessary, the spacer sleeve should be replaced with a dimensionally accurate replacement part to ensure smooth wheel operation.
