Abstract
A bearing assembly includes a cylindrical configuration with a radial direction, a circumferential direction and defining a bearing assembly longitudinal axis, a first axial end, and a second axial end, an inner radial race, an outer radial race, a bearing member configured to be disposed radially between the inner radial race and the outer radial race, and a retaining ring configured to engage the inner radial race and the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race once assembled.

A bearing assembly comprising:
- a cylindrical configuration with a radial direction, a circumferential direction and defining a bearing assembly longitudinal axis, a first axial end, and a second axial end;
- and including
- an inner radial race;
- an outer radial race;
- a bearing member configured to be disposed radially between the inner radial race and the outer radial race;
- and
- a retaining ring configured to engage the inner radial race and the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race once assembled;
- wherein the outer radial race includes an inner radial surface defining a first notch disposed adjacent the first axial end, the first notch being configured to receive the retaining ring, the inner radial surface also defining a first bearing member receiving slot disposed axially adjacent the first notch, and the inner radial race includes an outer radial surface defining a second notch disposed adjacent the first axial end, the second notch being configured to receive the retaining ring, the outer radial surface further defining a second bearing member receiving slot disposed axially adjacent the second notch, the inner radial race defining a third notch and the assembly further comprising an O-ring configured to be disposed in the third notch.
