Abstract
A thrust bearing assembly having a plurality of rollers positioned in a cage is provided. A first race washer is positioned on a first axial side of the rollers and the cage, with the first race washer including a first axially extending flange axially overlapping the cage and the rollers, and having at least one protrusion extending in a direction away from the cage. A first retention band including a first axially extending band and a first retaining flange that extends radially from the first axially extending band is provided. The first retention band has at least one recess or opening and is complementary in size to the first race washer flange and engagable thereon. Engagement is accomplished via the at least one protrusion on the first axially extending flange engaging the at least one recess or opening in the first retention band. The first retaining flange has a width that is sized to overlap a portion of the cage on a second axial side. A second race washer and second retention band can be provided for a fully encapsulated thrust bearing assembly.
