Impact on bearing life

The cleanliness of bearings has a significant impact on their lifespan. Special tests have been conducted on bearings for this purpose, and the results show that the difference can be several times or even tens of times greater. The higher the cleanliness of the bearing, the longer its lifespan. Experiments have shown that lubricating oils with different cleanliness levels have a significant impact on the lifespan of ball bearings. So, improving the cleanliness of lubricating oil can extend the service life of bearings. In addition, if the lubricating oil contains dirt particles below 10um, the service life of bearings can also increase several times.

The impact on vibration noise

Impact on vibration

The test results of the bearing test center indicate that cleanliness seriously affects the vibration level of the bearing, especially the vibration in the high-frequency band is more significant. Bearings with high cleanliness have low vibration speed values, especially in the high-frequency band.

Impact on noise

Experiments have been conducted on the impact of dust in bearing grease on noise, proving that the more dust there is, the greater the noise.

The impact on lubrication performance

The decrease in bearing cleanliness not only affects the formation of lubricating oil film, but also causes the deterioration of lubricating grease and accelerates its aging, thereby affecting the lubrication performance of lubricating grease.
