ONE-PIECE METALLIC BALL BEARING CAGE

摘要

A flat, thin ring is formed into a modified ring having bridge material between adjacent, initial ball pockets (14). Movable anvils (12) having a rounded surface are positioned within the initial ball pockets and the bridge material is reformed such that a substantially flat bridge is formed between adjacent final ball pockets conforming to more than a 180 degree circumference of the rounded surface. The movable anvils (12) are then moved such that the final ball pockets do not conform to more than a 180 degree circumference of the rounded surface to facilitate removal of the movable anvils (12) from the final ball pockets. A method of assembling a ball bearing assembly is also described.
