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.

Abstract: A shaft seal includes a body portion and a radially protruding lip portion. The body portion has a radial wall with at least one radial groove. The lip portion is integrally formed with the body portion and deflectable for sealing engagement with a shaft. In an example embodiment, the seal is a single piece manufactured by injection molding. In an example embodiment, the seal includes nylon or carbon filled polyamide 46.

Abstract: A thermal compensation element that generates an optimal bearing pre-load. The thermal compensation element has a bearing housing with a recess, a bearing outer ring arranged at least partially within the recess, a bearing shaft with a bearing inner ring arranged axially inward of the bearing outer ring, a piston with an outer sealing ring fixed in the recess axially between the bearing housing and the bearing outer ring, and a fluid supply port. The port increases or decreases pressure at the piston via a pressurized medium, allowing adjustable axial forces applied to the end of the hearing shaft by the piston to generate optimal bearing pre-load conditions.
