Abstract

A bearing cage for a rolling-element bearing includes a plurality of bearing cage segments configured to receive rolling elements in rolling-element pockets. Also included is at least one assembly wire, and each of the cage segments includes a coupling arrangement configured to thread the bearing cage segment onto the at least one assembly wire such that at least one rolling-element pocket is formed by two of the plurality of bearing cage segments adjacent in the circumferential direction that are threaded on the assembly wire. The bearing cage also includes an assembly device configured to convey an end of the assembly wire from an installation position to an axially far-side coupling arrangement of a bearing cage segment, through the axially far-side coupling arrangement of all bearing cage segments located on a bearing inner ring, and back again towards the installation position.
