A cage for a rolling element bearing and a method for the production thereof. The cage has either an increased number of rolling elements or improved load-bearing capacity. A The cage has a plurality of cage pockets for receiving the rolling elements, two side rings and a plurality of cross-ribs. The cross-ribs connect the side rings such that the cage pockets are formed. The cage pockets have milled-out or drilled-out corner regions. hereinafter collectively referred to as milled-out corner regions, The corner regions, in a cutting plane perpendicular to the axis of rotation of the cage, have a radial milling course in the direction of the axis of rotations. The milling course, at least in a partial section, is configured at an incline with respect to a radial vector placed through the partial section and the axis of rotation, and is configured at an incline in the direction of the cage pocket.
