Root cause analysis seminar of bearing failure
The International Standards Organization 15243 established a bearing failure mode.
The following failure modes will be described:

Fatigue:
» Fatigue induced by underground» Fatigue
induced by surface

Wear:
»Abrasive wear
» Adhesive wear

Corrosion:
»Moisture Corrosion
» Friction Corrosion
»Vibration Corrosion

Electric corrosion:
»Excessive voltage
» Current leakage

Plastic deformation:
»Overload
» Fragmentation indentation
»Indentation treatment

Fracture and cracking:
»Compression fracture
» Fatigue fracture
»Thermal cracking

Bearing failure root cause analysis program The complete failure analysis process should cover

1. Determine the most complete operating condition information.
2. Related photos in the process.
3. Comparison of lubricant samples in use and unused.
4. Mark the bearing and its location in the equipment.
5. Carefully disassemble the bearing to avoid unnecessary additional damage.
6. Check other machine parts to determine collateral damage.
7. Confirm the bearing base and valve seat.
8. Confirm the condition and distribution of lubricant in the bearing. If possible, take additional samples.
9. Clean the bearings and components, and if possible, record the logo, brand and full name.
10. Realize the analysis of bearings and corresponding parts. Take other photos.
11. Compare the failure mode standard photos provided by the International Standards Organization 15243 and/or the bearing manufacturer to determine the cause of the failure.
12. Determine the necessary corrective actions to avoid the same failure again.
13. Protect and retain faulty bearings for future comparison.
14. Example: Some of the above cases will be shown.
15. Interactive exercise: During the seminar, some interactive cases of bearing failure will be shown

16. Conclusions and suggestions.
