Abstract

A bearing cage for a rolling-element bearing includes first and second axially spaced-apart side rings extending in a circumferential direction, each side ring being split in the circumferential direction along a line of separation, thereby defining mutually-opposing bordering surfaces on first and second bearing cage sections. A first projection and a corresponding first opening are disposed on or in the mutually-opposing bordering surfaces of the first and second bearing cage sections. The first projection is insertable into the first opening in the circumferential direction to fix the bearing cage sections in at least a first direction. A second projection and a corresponding second opening are disposed on or in radially-extending, mutually-opposing bordering surfaces of the first projection and first opening. The second projection and second opening fix the bearing cage sections to each other in at least two additional directions, which are each perpendicular to the first direction.
