There are three common failure forms of rolling bearings

2021-11-12

In the use of rolling bearings, there are many ways to lead to the failure of rolling bearings. In the daily use of rolling bearings, there are mainly three common failure forms: fatigue, plastic deformation and abrasive wear. For these three failure forms of rolling bearings, the bearing network is described in detail as follows.

1. Fatigue: for rotating rolling bearings, fatigue pitting is the main failure form, so it is mainly for life calculation, and then static strength check when necessary.

2. Plastic deformation: for bearings with no rotation, low speed or swing, local plastic deformation is the main failure form, so it is mainly used for static strength calculation.

3. Abrasive wear: For high-speed bearings, heating and even gluing are the main failure forms, so the limit speed should be checked in addition to the life calculation.
