What maintenance does deep groove ball bearings need after long-term operation?

In mechanical systems, deep groove ball bearings are one of the vital components. They are responsible for supporting and transmitting rotational motion, and maintaining the stability and reliability of the system under load conditions. However, prolonged operation can lead to accumulation of dirt, increased friction and wear inside the bearing, thereby affecting its performance and life. Therefore, regular maintenance and upkeep is essential to ensure the normal operation of deep groove ball bearings and extend their service life.

Cleaning and lubricating bearings is one of the basic steps of maintenance. As operating time increases, dust, dirt, and other impurities may accumulate inside the bearings, causing lubricant failure and increased friction. Therefore, regular cleaning of bearings and relubrication as needed can effectively reduce friction and wear and increase the service life of bearings.

Secondly, regular inspection of bearing temperature is also an important part of maintenance work. Abnormally elevated bearing temperatures may indicate a bearing problem, such as insufficient lubrication, increased friction, or bearing damage. Therefore, regularly monitoring the temperature changes of bearings and promptly detecting and handling abnormal temperatures can help prevent bearing damage and failure.

Damage to the bearing seal will cause external impurities to enter the inside of the bearing, affecting its normal operation. Therefore, regular inspection of the integrity of the seals and timely replacement of damaged seals will help keep the bearings clean and in good working condition. At the same time, check the radial clearance and axial clearance of the bearing to ensure that they are within the normal range, which can help prevent bearing damage and wear.

Regularly checking the installation status of the bearing seat and the tightening status of the fixing bolts, as well as recording the maintenance status, are also one of the important tasks for maintaining deep groove ball bearings. Timely detection and handling of bearing installation and fixing problems will help ensure the normal operation of the bearing and extend its service life. At the same time, recording maintenance status can help formulate more effective maintenance plans and detect potential problems in time to ensure the stable operation and reliability of the mechanical system.
