Hub bearing (wheel bearing) - undercarriage assembly (wheel suspension) of wheeled vehicles; rolling bearing of one design or another, providing connection, centering and free rotation of the wheel hub on the axle.

A wheel bearing set usually consists of at least the two rings (outer and inner ring), the roller or spherical rolling elements and the cage that surrounds it. The task of the rolling elements is to transfer the forces acting on one bearing while driving to the other bearing in the sense of a targeted stabilizing compensation. Depending on the car brand and vehicle model, other components are added to the wheel bearing set, which you can see from the images or descriptions of the products of the individual manufacturers.
