The bearing includes a retainer having a width being the distance between a first side and a second side of the retainer, an outer surface extending between the first side and the second side and an inner surface opposing the outer surface. The retainer also has a central portion having a first thickness T1, and tapered portions each having a second thickness T2. Each tapered portion 1) extends from one of said sides to said central portion up to 28% of the length of said retainer width, 2) tapers towards the inner surface of the retainer at an angle of 20° or less relative to said central portion, and 3) tapers away from the inner diameter surface of the outer ring.
