Abstract
A bearing assembly is provided including at least one needle roller that is resiliently compressible in response to a load applied to an exterior surface thereof. In addition, a method is provided for taking up a clearance between one or more first rollers and a bearing race in which the rollers are positioned. At least one resiliently compressible second roller is provided rollably secured within the bearing. The compressible second roller has an outer diameter greater than an outer diameter of any of the first rollers, such that the compressible second roller resiliently compresses when the bearing is positioned in the bearing race. Forces generated by compression of the resiliently compressible second roller urge the first rollers against a surface of the bearing race, thereby taking up the clearance between the first rollers and the race.
