1. Keep bearings lubricated and clean

Before inspecting the bearing, the bearing surface should be cleaned first, and then the parts around the bearing should be disassembled. Pay special attention that the oil seal is a very fragile part, so do not use too much force when inspecting and removing the bearing, so as not to cause parts. damage. If the oil seal of the bearing and its surrounding parts is in poor condition, please replace it to avoid damage to the bearing due to poor oil seal.

2. Ensure the quality of bearing lubricant

Many people later found that bearing life was too short, and among other factors, the quality of the lubricant was directly affected. The test method of bearing lubricant is: friction point lubricant between two fingers, if there is contamination, you can feel it; or apply a thin layer of lubricant on the back of the hand, and then check the seal. Then replace the bearing lubricant.

3. Bearing working environment

When inspecting bearings, do not expose them to contamination or moisture. If work is interrupted, the machine should be covered with oil-paper-plastic board or similar material. The working environment of the bearing is also very important. There are many imported bearings in the machine. This is because the working environment does not work, resulting in the end of the imported bearing life.

4. Bearing seal

The purpose of bearing sealing: to prevent dust, moisture and impurities from entering the bearing, and also to prevent the loss of lubricant. Good sealing can ensure the normal operation of the machine, reduce noise and prolong the service life of related components.

The above is an introduction to the daily maintenance of bearings. It is mainly explained from four aspects. In fact, these four aspects are also interrelated, such as the sealing of the bearing to keep the bearing lubricated and clean, and the working environment. It’s also about cleaning. Therefore, the bearing maintenance work is carried out around the four words of clean, lubricated, sealed and environment.
