A bearing ring is a component of a rolling bearing system, consisting of two rings: the inner ring and the outer ring. These rings provide the raceways for the rolling elements (e.g., balls or rollers) and allow the bearing to support radial and axial loads while minimizing friction. Bearing rings are critical in applications like motors, gearboxes, pumps, and other machinery where rotational motion and load-bearing capabilities are required.
