The relationship between accuracy level and performance of deep groove ball bearings

In automated production lines, the failure of deep groove ball bearings may cause the entire production line to shut down, affecting production efficiency.

Common fault symptoms: In a certain automated production line, it was found that deep groove ball bearings were experiencing heating, increased noise, and intensified vibration. After inspection, it was found that the raceway surface of the bearing was worn and peeled off, and the rolling elements were also damaged to varying degrees.

Fault cause analysis: Through the analysis of the faulty bearing, it was found that the main reason was the fatigue wear of the bearing caused by long-term operation, coupled with the high load on the production line exceeding the rated load of the bearing, which accelerated the damage of the bearing. In addition, poor lubrication is also an important factor leading to bearing failure. The performance of lubricating grease decreases and is not replenished in a timely manner, resulting in excessive frictional heat generated during the operation of the bearing.

Solution: In response to the above issues, we have replaced the deep groove ball bearings with higher load-bearing capacity and optimized the lubrication system. We regularly replenish the lubricating grease to ensure that the bearings are always in good lubrication condition. At the same time, the operating parameters of the production line were adjusted to avoid bearing overload operation. Through the implementation of these measures, the operational stability of the production line has been significantly improved, and the failure rate of deep groove ball bearings has been significantly reduced.
