Abstract
A cage (1) for cylindrical rolling elements (5) comprising two side rings (2, 3) connected to each other by circumferentially uniformly spaced crossbars (4) so that receiving pockets (6) are formed for the rolling elements (5) is characterized in that opposing end surfaces (8) of the pockets (6) comprise projections (11) which extend inwards in axial direction and bear against end faces of the rolling elements (5) which prevents an axial offset between the rolling elements (5) and the cage (1) so that after insertion and suspension of the first rolling element (5), the cage (1) can be filled with the rest of the rolling elements (5) without their being damaged.
