Abstract
A strip of metal is pierced intermediate the edges thereof to form slots for rollers and is bent adjacent the edges to form flanges. Each bend intersects the slots such that the slots wrap around the bends into the flanges. The strip of metal is then formed into a circular hoop such that the flanges form axially spaced end rims to retain the rollers axially. Crossbars between the slots are offset radially in a sigma configuration to retain the rollers radially. Edges of the slots may be specially formed to facilitate flow of lubricant through a roller bearing.
