1. Contact fatigue failure: refers to the material fatigue failure caused by the alternating stress on the working surface of the bearing.

2. Wear failure: refers to the failure caused by the continuous wear of the metal on the working surface due to the relative sliding friction between the surfaces.

3. Fracture failure: The main reasons are defects and overload. When the external load exceeds the material strength limit and causes the parts to break, it is called overload fracture. The main cause of overload is the sudden failure of the main machine or improper installation.

4. Corrosion failure: Some rolling bearings are inevitably exposed to water, water vapor and corrosive media during actual operation. These substances can cause rust and corrosion of rolling bearings. In addition, rolling bearings are also affected by microcurrents and static electricity during operation, causing current corrosion of rolling bearings.

5. Clearance change failure: During the operation of rolling bearings, due to the influence of external or internal factors, the original matching clearance changes, the accuracy is reduced, and even "bite" is caused, which is called clearance change failure.
