This end cap closes off the housing bore at the shaft end, providing a fixed cover element for the assembly. It is supplied by INA under the catalog symbol KASK10, with a net mass of 41.87 g, allowing straightforward handling during installation. As a closing component rather than a rotating part, it serves to seal the open end of the bearing housing, protecting the internal bearing arrangement from external contamination while keeping the assembly compact. Its light weight makes it suitable for mounting without additional support, and it is fitted directly onto the housing without requiring separate fasteners beyond the standard assembly procedure for KASK10.
