The cleanliness of skf bearings has a considerable impact on the life of radial thrust ball bearings, with the result that the difference is several times or even dozens of times. The higher the cleanliness of the radial thrust ball bearing, the longer the life and the like. The test shows that the lubricating oil with different cleanliness has a great influence on the life of the ball skf bearing. Therefore, improving the cleanliness of the lubricating oil can prolong the life of the radial thrust ball bearing. In addition, if the lubricating oil-containing dirt particles are controlled below 10 um, the life of the radial thrust ball bearing is also increased several times.
2. Influence on vibration and noise
(1) Effect on vibration The degree of cleanliness seriously affects the vibration level of the radial thrust ball bearing, especially in the high frequency band. The skf bearing with high cleanliness has a low vibration speed value, especially in the high frequency band.
(2) Effect on noise The grease company has tested the influence of dust in the grease of the radial thrust ball bearing on the noise, which proves that the more dust, the greater the noise.
3. Influence on Lubrication Performance The decrease in the cleanliness of the radial thrust ball bearing not only affects the formation of the lubricating oil film, but also causes deterioration of the grease and accelerates its aging, thereby affecting the lubricating performance of the grease.
