A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction. Wheel bearings are safety critical components designed to sustain radial and axial loads caused by gravitation, acceleration, breaking & cornering forces, so they need to be replaced when they stop working properly.
These are different from the engine bearings, as there is no constant source of lubrication for the wheel bearings, which means they need to be tight enough to keep away water and road dust. They also support the entire vehicle weight while driving, which is why they suffer a lot of abuse from rough roads, potholes, as well as lateral forces when turning.

The main function of hub bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component.
