Wheel Hub Bearing

Wheel hub bearing assemblies integrate the wheel hub, wheel bearings, and in some designs, the ABS wheel speed sensor hub into a single unit. These components are located at the wheel suspension and facilitate smooth wheel rotation while supporting vehicle weight. Pre-assembled designs reduce installation time and improve accuracy by eliminating the need for individual bearing pressing. Internal components typically include sealed, lubricated tapered or angular contact ball bearings designed for high radial and axial load capacity. Variations exist with integrated hub flanges for specific vehicle makes and models, and some feature interchangeable wheel stud designs for servicing.
