Abstract
A cage for the rollers in a roller bearing in which the roller axes (2) define an angle with the bearing axis (3) has two annular portions (4, 5) and intermediate cage bars (6) defining cage pockets (7). The bars are situated radially inside of the roller axes with respect to the bearing and a flange (8) for guiding the roller by contacting their ends is extending radially outwards from one of the annular portions (4). A protrusion (9) is arranged on the flange (8) in connection to each pocket (7) or insertion into a recess in the adjacent roller end and thereby keeping the roller in the cage pocket. A recess (10) in the other annular portion (5) opposite each protrusion (9) simplifies the snapping of the roller into its pocket in the cage.
