Abstract

The invention relates to a rolling bearing cage comprising a first cage ring, a second cage ring, and web elements which interconnect the two cage rings (1). Adjacent web elements form a pocket that accommodates a rolling member (25). The aim of the invention is to design a stable rolling bearing cage that is easy to produce. Said aim is achieved by the fact that at least one of the web elements is planar and comprises a planar element (8) and a fastening element. Furthermore, the web element extends in such a way in a radial direction that the axis of the rolling bearing cage is arranged on a plane defined by the planar element (8).
