A cage for a radial roller bearing of limited width availability, which has a first flange, a second flange spaced from the first flange, and cage bars that extend between the first flange and the second flange so as to form a plurality of roller pockets. The cage bars, together with the first flange and the second flange form an S-shaped or a Z-shaped contour. The cage aids in properly guiding roller elements in bearings of limited widths. The cage prevents rolling elements from overrunning or under running the cage bar. The cage also provides for proper contact of the rolling elements to push the cage around the radial bearing. Further, the cage allows for inner retention, outer retention, or both inner and outer retention of the rolling elements.
