Abstract

A sheet metal bearing cage segment includes a first sheet metal ring section, at least one second sheet metal ring section, and a plurality of bridges connecting the first ring section and the at least one second ring section to each other, adjacent pairs of the bridges forming pockets configured to receive at least one rolling element. At least one edge of the first ring section and/or at least one edge of the at least one second ring section and/or of one of the bridges is at least partially formed by laser cutting. Also a method of forming a sheet metal bearing cage at least partially by laser cutting.
