[0002] Wheel hub bearings are suitable for cars running at high speeds and under heavy load conditions. They can effectively reduce the vibration and impact of bearings during operation, extend the service life of bearings, and improve the stability and safety of cars. By strengthening the design of flange journals, the load-bearing capacity and anti-fatigue performance of wheel hub bearings can be effectively improved, and the deformation and damage of bearings during high-speed rotation can be reduced, thus ensuring the stability and reliability of cars during driving.

[0003] The automobile wheel hub bearings of the prior art have the following disadvantages during use:
