Wheel hub bearings
Wheel hub bearings are one of the key parts of the automobile. Its main function is to carry weight and provide precise guidance for the rotation of the wheel. The traditional automobile wheel bearing is composed of two sets of tapered roller bearings or ball bearings.
Models
The first-generation wheel hub bearings are composed of double row angular contact ball bearings or double row tapered roller bearings,used for driven front and rear wheels.

Symptoms of a failing wheel hub bearings
Noise – Worn wheel bearings will generate frictional noise when rotating.
Wheel shaking – The wheel will shake when the car is running, and the vehicle shake will increase.
Poor rolling – Decreased power,abnormally high temperature.
