Wheel Bearing is the central element of the chassis system, the radial bearing is responsible for mounting the wheel to the steering knuckle and the hub. Car handling depends on this part’s quality and regular maintenance. Types of wheel bearings Single-row radial ball bearings. They require careful installing, as incorrect installation can cause rapid failure of the part. Radial roller or double row bearings. They can handle twice the load of the single row ones. They do not need regular maintenance due to design features. Tapered roller (radial thrust) bearings. They withstand axial and radial load due to the shift in the direction of the rolling elements. The construction of wheel bearings The outer ring. Rolling element. The inner ring. The cage (polymer, steel, stamped, brass or machined). Tips for operating wheel bearings Front hub components are more prone to wear and tear, and therefore require regular replacement. Rear wheel bearing fails less often. To extend the parts ...
