Resilient Ball Bushing® bearing mounts are sometimes used when absolute rigidity is not essential and where a slightly larger housing bore can be accommodated. The self-aligning feature of these mounts guarantee uniform load distribution over the entire length of the load carrying balls and compensates for slight errors in housing bores and parallel 60 Case® LinearRace® alignment. The mount consists of a band of resilient material that can be easily mounted to the outside diameter of the Ball Bushing® bearing. After it is installed in the housing bore, it provides permanent resilient, self-aligning support for the bearing.
