Abstract
A cage for a roller bearing is provided. The cage has a ring-shaped base body with a plurality of pockets for receiving rolling elements. The base body is formed by two side rings arranged in a defined axial distance and by a plurality of pocket elements, which are located between the side rings. Each pocket element has two face sides designed for contacting a rolling element. The connection between the pocket element and each of the side rings is established by at least one beam joined with one of the side rings and the pocket element. The beam is a positive substance joined with one of the side rings and the pocket element and has a ring-shaped or elliptical cross section in a section perpendicular to the longitudinal extension of the beam.
