Abstract: A bearing, including: an inner ring defining a first groove; an outer ring including a radially inner surface, the radially inner surface facing an axis of rotation of the bearing and defining a second groove and a third groove; a cage radially disposed between the inner ring and the outer ring; a plurality of balls retained by the cage, and disposed in the first groove, and in the second groove; and a preloaded resilient washer assembly including a rigid washer and a resilient washer including a radially outermost surface disposed in the third groove. The resilient washer urges the rigid washer away from the outer ring in an axial direction parallel to an axis of rotation of the bearing.

Abstract: A bearing, including: an inner ring defining a first groove; an outer ring including a radially inner surface, the radially inner surface facing an axis of rotation of the bearing, defining a second groove, and defining at least one third groove; a cage radially disposed between the inner ring and the outer ring; a plurality of balls retained by the cage, and disposed in the first groove, and in the second groove; an annular sleeve including a first portion disposed in the third groove; and a resilient element urging the outer ring and the annular sleeve away from each other parallel to the axis of rotation of the bearing.

Abstract: A shaft assembly is disclosed herein. The assembly includes a shaft, an outer housing, a bearing assembly, and a preload spring. The bearing assembly includes an inner ring mounted on the shaft and defining an inner raceway. An outer ring defines an outer raceway and an annular groove, and the outer ring is arranged within the outer housing. A plurality of rolling elements are arranged between the inner raceway and the outer raceway. The preload spring includes: a washer body positioned within the annular groove of the outer ring, and a flange extending axially from the washer body and contacting the outer housing.

Abstract: A high-speed ball bearing utilizes a two-piece cage. Each of the two cage halves have a set of posts and a set of holes located circumferentially between the half pockets. The posts are long enough that they stick out from the corresponding holes after the cage halves are mated together. Heat is applied to the ends of the posts, causing them to form vulcanized bonds with the surrounding material of the opposite cage half. These bonds reliably hold the cage halves together even at high rotational speeds.

Abstract: A combination bearing is configured to support both axial loads and radial loads. The combination bearing includes a bearing housing including a radial bearing ring and an axial bearing cup. Radial rolling elements are located within the radial bearing ring, are configured to support a radial load, and collectively rotate about a central axis. Axial rolling elements are located within the axial bearing cup, are configured to support an axial load, and are axially offset from the radial rolling elements along the axis. An axial washer directly contacts the axial rolling elements. The axial washer is configured to support the axial load and transfer it toward the axial rolling elements. A sealing washer is disposed about the axis and spaced axially from the axial washer. Oil is retained within the combination bearing during free-wheeling conditions with little to no external oil supply.
