Why do some bearings last a long time while others need to be replaced frequently in the same working environment? That's manybearingsConfusion often encountered by industry practitioners. In fact, the life of a bearing is closely related to its use, maintenance and other factors. So, in daily use, how can we tell if a bearing needs to be replaced?
Here are some key points to determine if a bearing needs to be replaced:
1. Check the dimensional accuracy and rotation accuracy
First of all, check the dimensional accuracy and rotation accuracy of the bearing. If significant deviations are found, this could be a sign of bearing wear or damage.
2. Inspection of appearance and mating surface
Observe the appearance of the bearing, and inspect the raceway surface, cage and sealing ring for damage or abnormality. Pay particular attention to cracks, chips, or peeling.
3. Analysis of lubrication situation
Check the lubrication of the bearings. If the lubricant is insufficient or the contamination is severe, it may be the cause of premature bearing wear.
4. Evaluation of machine performance and operating conditions
Consider the performance, criticality, and operating conditions of the machine. If the machine is constantly operating under high loads or harsh environments, the life of the bearings may be affected.
5. Regular inspection and maintenance
In order to ensure the long-term stable operation of the bearing, it should be inspected and maintained regularly. This includes cleaning bearings, changing lubricants, tightening loose parts, etc.
If any of the above defects are found, such as cracks, chips, peeling, jamming, severe wear, etc., a new bearing should be considered. In addition, if the bearing is overheated, discolored or the seal is broken, it should also be replaced in time.
In short, in order to ensure the long-term stable operation of the bearing and give full play to its performance, regular maintenance and inspection should be carried out. By discovering and dealing with bearing problems in a timely manner, the service life of bearings can be effectively prolonged, and production efficiency and economic benefits can be improved.
