What are the effects of cleanliness on the performance of 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 carried out professional tests, and the result is that the difference is many times or even dozens of times. The higher the cleanliness of the bearing, the longer the life of the test shows that the grease with 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 multiplied.

Effects on vibration and noise

Effect on Vibration

The test results of the bearing test 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. Bearings with high cleanliness have low vibration rate values, especially in the high frequency band.

effect on noise

The impact of the floating dust in the bearing lubricating 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 lubricating grease, thereby affecting the wetting performance of the lubricating grease.
