Abstract
A bearing assembly includes first and second races, a plurality of ball bearings positioned between the first and second races, and a spacer positioned between each of the ball bearings. The spacers each include a body defining opposite first and second sides, a first substantially concave pocket located at the first side of the body, and a second substantially concave pocket located at the second side of the body. The first and second substantially concave pockets each define a central region having a first radius of curvature about a first center point and an outer region adjacent to the central region that has a second radius of curvature about a second center point. The first and second center points are spaced from one another, and the body includes a portion extending in between at least the respective central regions of the first and second substantially concave pockets.
