Wheel Bearing 43440-78A20

What is a wheel bearing?

A wheel bearing is a set of steel balls held together by a metal ring, also known as a race. It is located in the hub of the vehicle's wheel, and it serves four main functions:

1. Bearing weight: It bears the weight of the entire vehicle and any cargo it may carry. It transfers these vertical loads to the wheel, and then to the road.
2. Reducing friction: By using a precision ball or roller structure and high-quality lubricants, it provides a low coefficient of friction to ensure that the wheel rotates efficiently and without resistance.
3. Maintaining stability: It ensures the stability of the wheel relative to the vehicle and prevents wheel wobble and unstable movements caused by loose or damaged bearings.
4. Sealing protection: Modern wheel bearings usually have a sealed design to prevent dust, water, and other pollutants from entering the bearing, thereby extending its service life.
