Abstract

A roller bearing includes a first race, a second race, and a cage disposed between the first and second races. The cage has an inner rim and a plurality of webs extending radially outboard from the inner rim and being circumferentially arranged around the inner rim to be spaced apart to define pockets. The webs have flanges that extend axially. Portions of the inner rim form inner guide surfaces of the pockets. The cage further includes a wavy outer rim circumscribing the inner rim. The outer rim has radially outer portions attached to the flanges and radially inner portions forming outer guide surfaces of the pockets. The outer rim and the flanges cooperate to define cutouts interleaved with the webs. Cylindrical roller elements are disposed in the pockets between the first and second races and have first ends adjacent the inner guide surfaces and second ends adjacent the outer guide surfaces.
