    Abstract: A method for producing a cage having a body with multiple pockets for rolling elements, the method providing: a) defining a cage basis geometry that provides a radial outer and/or inner surface for contacting a bearing ring and multiple surfaces of the pockets for contacting the rolling elements; b) defining a part of the radial outer and/or inner surfaces as being unalterable surfaces; c) calculating the cage stress distribution when applying a defined stress force from a mathematical model; d) defining cage volume sections where the stress is below a defined threshold; e) removing a part of the volume sections defined according to step d) taking into account the unalterable surfaces according to step b) and the surfaces of the pockets that are unalterable surfaces; f) defining the cage geometry with the removed volume sections; g) manufacturing the cage according to the geometry as defined according to step f).

    Abstract: The invention relates to a bearing cage (1) for receiving rolling elements (6). In addition to two rings (2, 3), the bearing cage also has a plurality of webs (4) which run axially between the rings (2, 3). In order to prevent the rolling elements (6) from falling out of the pockets (5) formed between the rings (2, 3) and the webs (4), the webs (4) are at least provided with a groove (7a) which runs in the direction of the respective web (4). When the rolling elements (6) are inserted into the pockets (5), a tool (9) engages into the groove (7a) and bends the edge region (11) of the web (4) in the direction of the rolling elements (6) inserted into the pockets (5).

    Abstract: A roller bearing cage (1, 40) has at least a first side ring (2, 41, 52) that extends in the circumferential direction. The first side ring (2, 41, 52) comprises an opening point (3, 8, 58). This opening point is designed for opening the side ring (2, 41, 52) in order to mount the side ring (2, 41) so that a circumference of the side ring (2, 41, 52) can be enlarged.
