Abstract: A new and improved high speed snap-in type bearing retainer or cage and a bearing construction wherein the retainer includes means to effect retainer piloting and thereby enhance retainer control and stability during high speed applications while accommodating ease of retainer installation into an associated bearing construction. The retainer is of a one-piece plastic or nylon construction having a cylindrical retainer body and a plurality of ball receiving pockets positioned on one side of the body so as to extend axially outward thereof. The pockets include entrance areas at the outermost ends thereof which are defined by opposed, yieldable fingers dimensioned to capture a ball member therein. Web areas are interposed between adjacent pockets circumferentially of the retainer body and extend axially outward a distance greater than the pocket entrance areas. A first pilot rim is provided circumferentially of the retainer body to pilot against at least one of an associated inner and outer bearing race.
