Bearing abnormal operation condition and the corresponding countermeasures.
| conditions | Speculate reasons | measures |
|
Abnormal temperature rise |
Grease too much or too little | After checking, inject the right amount of lubricat |
| Load increased | Adjust load, and modify bearing clearance or cooperate with clearance | |
| Bad installation | Improve the bearing process, installation accuracy, and the size of the prestressing force | |
| Cooperate with surface peristalsis or bearing external friction | Adjust precision or change the bearing | |
|
Big vibration |
Bad installation | Fixed axis or shell with precision, and adjust the preload |
| Other things incasion | Improve the shaft and shell surface cleanliness, and improve the installation way | |
| Bearing wear or deformation | Change the bearing | |
| Oil leakage or discoloration | Too much grease or seal rickety, outside oil, water invasion, etc | Adjust the grease capacity or replace the seal form, and improve the bearing work environment |
| Big noise | Bearing damage, peel, and clearance is too large | Change the bearing |
| Other things invasion | Clean parts, replace the seal device, and use clean grease |
