Automotive wheel bearings are critical components in vehicle hub assemblies, designed to support radial and axial loads generated during driving, braking, and cornering. They ensure smooth wheel rotation, reduce friction, and maintain precise wheel alignment under varying road and load conditions.
These bearings are widely used in passenger cars, trucks, trailers, and light commercial vehicles, providing stable performance, long service life, and improved driving safety.
