A roller bearing cage 16 with roller bearing pockets 18 which are arranged one next to the other in the circumferential direction and have the purpose of holding load-bearing roller bodies 10 of a roller bearing, wherein at least one end piece 14 which engages behind a roller bearing component 12 is formed on the roller bearing cage 16. The end piece 14, which is ideally embodied as a retaining claw, holds the inner ring and the roller body 10 together, but can be removed after or during the assembly by means of a predetermined rupture point 15, in order to make room for a further component, such as for example a sealing arrangement. As a result, despite the installation assistance, optimum use of the installation space is provided.
