There should be a short description so that people quickly can see if this is the relevant K-brief. A describing picture helps those who are more of a visual nature.
Current situation
This section should be updated very often. Ask yourself questions like: Has anything been sent to external laboratories? Has any new test results come out?
Root cause analysis
List all the possible root causes
- No lubrication
- Metallurgical compatibility
- Bearing surfaces too soft
- Bearing loads too high
Proposed countermeasures
| Countermeasure | Effect on root cause | ||
|---|---|---|---|
| A | Lubricate shaft | Recommended | |
| B | Change metal in the shaft | Upset the metallurgical compatibility | Not recommended |
| C | Harden the hub and the shaft | Harder bearing surfaces tend to weld less | Investigate further |
| D | Reduce bearing loads | Not recommended |
Conclusion
After a meeting with supplier, the conclusion is to implement lubrication
