Abstract

A roller bearing cage has cage rims (1,3) on both of its axial ends. One cage rim (1) has a circumferential inside groove (5). The other cage rim (3) carries at least one holding lug (7) that protrudes radially. The holding lug (7) interlocks into the corresponding groove (5) of another such cage, wherein roller bearing cages with two or more rows are formed as a construction unit, which can rotate relative to one another.
