Abstract
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.
