How does cleanliness affect the performance of the bearings used?

Effect on bearing life

The cleanliness of the bearing has a great influence on the life of the bearing, so the bearing has been professionally tested, and the results are many times or even dozens of times different. The higher the cleanliness of the bearing, the longer the life, and the test shows that the grease of different cleanliness has a great influence on the life of the ball bearing. Therefore, improving the cleanliness of the grease can increase the life of the bearing. In addition, if the grease containing waste particles is controlled below 10um, the life of the bearing is also doubled.

Effects on vibration and noise

Effect on Vibration

The test results of the Bearing Inspection and Management Center show that the cleanliness seriously affects the vibration level of the bearing, especially the vibration in the high frequency band is more obvious. Clean bearings have low vibration rate values, especially at high frequencies.

effect on noise

The influence of the floating dust in the bearing grease on the noise was tested, and it was confirmed that the more floating dust, the greater the noise. Effect on wetting properties

The reduction of bearing cleanliness will not only affect the production of grease film, but also continue to cause mildew and accelerate the embrittlement of the grease, thereby affecting the wetting performance of the grease.
