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.

A power generating bearing assembly comprising a power generating subassembly integrated into a bearing. The power generating subassembly utilizes the relative motion between a bearing inner ring and a bearing outer ring of the bearing to generate electrical power. A sealing system is attached to one of the bearings. The power generating subassembly includes an electrical generator in operational engagement with a magnetically polarized material. The electrical generator is attached to the non-sealing carrying bearing. The magnetically polarized material is integrated into a supported member, which is a unitary section of the seal that extends axially from an end surface of the bearing rings. The relative motion between the rings engages the electrical generator and the magnetically polarized material causing a generator core of the electrical generator to create an electrical current.
