Abstract

A bearing cage segment of a sheet metal cage includes first and second sheet metal ring sections and bridges therebetween defining a plurality of pockets for receiving rolling elements. A first circumferential joint edge of the segment is configured to connect to a second circumferential joint edge of the segment or to a second joint edge of another segment, and the first joint edge includes at least one alignment element, such as a projection or contour, that is configured to align the first joint edge radially, axially and/or circumferentially against the second joint edge which may include a complementary alignment element such as a recess or complementary contour.
