Abstract

A method of forming a bearing cage segment includes determining a path of a periphery of the bearing cage segment along a metal sheet, punching a plurality of openings in the metal sheet inside the path to form a plurality of pockets separated by a plurality of bridges and separating the bearing cage segment from the metal sheet at the path. The separating includes laser cutting first and second joint edges at a first end of the row and third and fourth joint edges at a second end of the row, where the first joint edge is spaced from the second joint edge in a length direction of the bridges and the third joint edge is spaced from the fourth joint edge in the length direction of the bridges.
