Automobile wheel bearings are one of the important parts of automobiles. They bear the weight of the vehicle and the pressure of steering. Long-term use or improper use may cause wear or damage, affecting the comfort and safety of the car, so they need to be replaced or repaired.

From the first generation to the third generation, the design of wheel hub bearing units has continued to evolve, not only improving integration and assembly accuracy, but also adding intelligent functions. These improvements help improve the safety, production efficiency and performance of the car.

There are obvious differences between ball bearings and roller bearings in terms of structure, load-bearing capacity, speed, application areas and characteristics.

Autoround analyzes the impact of bad wheel hub bearings on car performance from three perspectives: comfort performance, driving performance, and safety performance.
