Abstract

A method for manufacturing a bearing cage includes providing a bearing cage blank made from a metal plate, the cage blank including a cylindrical flange extending from a disk-shaped wall, punching a plurality of first openings through the cylindrical flange in a first direction to form a plurality of snap surfaces, and punching a plurality of second openings through the cylindrical wall in a second direction opposite the first direction to form a plurality of pockets. The second openings intersect at least two of the first openings, and punching the pockets removes a body of material from between the at least two of the first openings. Also a bearing cage formed by the method.
