Abstract
A roller bearing cage has a cage element adapted for retaining the generally cylindrically shaped rollers and allowing the rollers to be rollable therein. The cage element includes a main portion having a plurality of pockets, an outward flange portion extending outwardly in a radial direction and an inward flange portion extending outwardly in the radial direction. The outward flange portion is formed on a side edge of the main portion and the inward flange is formed on an opposite side edge portion thereof. The main portion defines the smallest diameter of the bearing cage and is less than the roller pitch diameter.
