Abstract

A sheet metal bearing cage segment includes a first ring section, at least one second ring section, and a plurality of bridges connecting the first and second ring sections to each other and defining a plurality of pockets between the bridges. The bearing cage segment includes first and second circumferentially directed joint edges, the first joint edge is configured to connect to the second joint edge of the bearing cage segment or to a second joint edge of another sheet metal bearing cage segment, and the first joint edge includes at least one body of welding material projecting from the joint edge. The body of welding material may be pressed against the second joint edge while leaving a gap between the joint edges, and the welding material can be liquified by a resistance welding process to connect the joint edges.
