Wheel bearings are sets of steel balls or tapers held together by a metal ring. They enable the wheels to rotate smoothly with minimal friction. At the center of a vehicle’s wheels are hollow pieces of metal called hubs. Wheel bearings fit tightly within the hubs and ride on metal axle shafts, which helps to reduce friction when wheels spin.
Wheel bearings are different from engine bearings in that there is no constant source of lubrication. This means that wheel bearings need to be tight in order to keep away debris, water, and dust. Additionally, they support the entire vehicle’s weight while it is operation, which is the reason they are subject to a lot of wear and tear.
Wheel bearing is one of the key parts of automobiles. Its main function is to carry weight and provide precise guidance for the rotation of the wheel. This requires it to bear not only axial load but also radial load.
