Abstract

A bearing race encapsulation apparatus, which has a spring assembly integrated into a hearing that allows the hearing to compensate for varying expansions and contractions caused by differences in temperature. The bearing race encapsulation apparatus includes an outer bearing ring with an end face and an outer face with a indent formed in the outer face. An encapsulation ring, which has a retention element that is snapped into the indent of the outer bearing ring, a first segment that extends axially outwardly from the retention element, and a second segment that extends radially inwardly from the first segment. A spring is arranged axially between the second segment of the encapsulation ring and the outer bearing ring to compensate for the expansion and contraction.
