Wheel hubs are the central component connecting the wheel assembly to the vehicle’s axle, enabling rotational movement. Positioned at the end of each axle, they house wheel bearings facilitating smooth and efficient wheel rotation. Hubs typically integrate an ABS sensor mounting point and may incorporate a stud or flange for brake rotor attachment. Construction materials commonly include ductile iron or aluminum alloy for durability and weight reduction. Variations exist to accommodate different wheel stud patterns, brake system types, and vehicle weight classes.
