Most of the bearing failures can be noticed in the early period and the root cause can be eliminated.
| Fault | Possible cause | Prevention |
|---|---|---|
| Fatigue (suffering) | Overload, insufficient lubrication, end of life | Correct bearing selection and lubrication plan |
| Wear | Pollution, spoiled lubrication | Improve sealing, replenish grease |
| Corrosion | Humidity, water intake | Suitable felt and corrosion resistant grease |
| electric erosion | current through the bearing | Insulated bearing or grounding |
| Plastic deformation | Impact, incorrect assembly | Correct mounting and method |
| Breaking and cracking | Extremely tight, faulty shaft | Check tolerance and spindle geometry |
