Claim 0:
1. A rolling bearing cage having a cage lock, the cage lock comprising two side rings which have a common axis of rotation and same basic dimensions and which are axially spaced apart from one another, and a plurality of cage webs which connect the side rings to one another and which are designed with rolling element guides projecting inwards from the cage over an inner diameter of the side rings, and between each cage web, cage pockets are formed for receiving rolling elements, wherein the rolling bearing cage is axially divided at at least one peripheral location and as a result has at least a first cage end and a second cage end, at each of the first cage end and the second cage end, mutually corresponding closure elements are arranged, and the side rings are designed with height-reduced end portions which are reduced to half a radial height (HS) of the side rings and which are arranged radially one above the other when the rolling bearing cage is closed, wherein, between the height-reduced end portions at the first cage end, a cage web, delimiting on one side in each case a last and a penultimate cage pocket, is arranged with a cross-sectional profile which is reinforced relative to the other cage webs, and the closure element at the first cage end is formed by an axial groove in the rolling element guide at a radial web surface of the cage web which delimits the penultimate cage pocket, while the closure element at the second cage end is formed by a partial web which connects the height-reduced end portions at the second cage end to one another and has a same material thickness as the end portions and which can be hooked into the axial groove in the rolling element guide of the cage web at the first cage end in such a way that the cage ends are secured in a peripheral direction and in both radial directions against unintentional loosening.
