清洁度对rbc轴承使用的性能有哪些影响?
　　rbc轴承的清洁度对rbc轴承寿命的影响相当大，rbc轴承曾为此进行了专门的试验，结果是其差别达数倍乃至数十倍以上。rbc轴承的清洁度越高，寿命越长等人的试验表明，不同清洁度的润滑油对球rbc轴承寿命影响很大。所以，改善润滑油的清洁度能延长rbc轴承的寿命，此外，若润滑油含污物颗粒控制在10um以下，rbc轴承寿命也成数倍增长。
　　对振动的影响：
　　rbc轴承试验中心的试验结果表明：清洁度严重影响rbc轴承的振动水平，尤其是高频带的振动更为显著。 清洁度高的rbc轴承振动速度值低，特别是在高频带。
　　对噪声的影响：
　　对rbc轴承润滑脂中的尘埃对噪声的影响做过试验，证明尘埃越多噪声越大。
　　对润滑性能的影响：

　　rbc轴承清洁度的下降，不仅影响润滑油膜的形成，还会引起润滑脂的变质和加速其老化，从而影响润滑脂的润滑性能下降。
