This end cap closes off the housing bore end, protecting the internal bearing arrangement from the ingress of dust and moisture and retaining lubricant inside the assembly. The component KASK08 has a net mass of 0.021 kg, making it a lightweight accessory sized to match the corresponding housing unit it is intended for. Fitting this cap requires no additional sealing elements, as it serves purely as a mechanical barrier at the open end of the housing bore. Its low mass and simple design make installation straightforward during assembly or maintenance, and it can be replaced independently without disturbing the bearing itself once removed.
