Introduction to common causes of damage to imported bearings

Most of the imported bearings are damaged for many reasons, such as excessively small bearing clearances caused by previously estimated loads, ineffective seals, and tight fits. Any of these factors have their particular type of damage and leave a special mark of damage. Therefore, inspecting the bearing of the damaged shaft, in most cases, its possible cause can be found.

In general, one-third of bearing damage is caused by fatigue damage, the other third is due to poor lubrication, and the other third is due to contaminants entering the bearing or improperly installed. However, these types of damage are also related to industry. For example, most of the pulp and paper industry is due to poor lubrication or contamination resulting in bearing damage rather than material fatigue.
