Abstract
A method is provided for producing an angular bearing cage from a sleeve-like blank. In order to significantly reduce the manufacturing costs compared to known solutions even for small series, the method comprises the following steps of: —Step A: providing a sleeve-like blank extending along an axis. —Step B: rolling a wall section to be formed of the blank while changing the angle of the wall section to be formed relative to the axis of the blank. —Step C: introducing rolling element pockets into the rolled wall section. A corresponding device and a correspondingly produced rolling bearing cage or angular bearing cage are also provided.

A method for producing a rolling bearing cage from a sleeve-like blank, comprising the steps of:
- step A:
- providing the sleeve-like blank extending along an axis;
- step B:
- rolling a wall portion to be formed of said blank while changing an angle of said wall portion to be formed relative to said axis of said blank;
- and
- step C:
- introducing rolling element seats into said rolled wall section,
- wherein the step B comprises the following sub-steps:
- sub-step B-2:
- moving a rolling tool and/or said blank such that said rolling tool rolls on a path along the inner circumference and/or along the outer circumference of said wall section to be formed and forms said wall section to be formed while reducing a thickness of said wall section as well as changing an inner circumference and/or an outer circumference of said wall section;
- and
- sub-step B-4:
- repeating sub-step B-2 until a desired shape of said wall section to be formed has been obtained, where said angle is changed with each repetition.
