The number of the protection components 4 is two groups and is symmetrically distributed, which is beneficial to the normal use of the bearing.

[0025] Please refer to Figures 1-6 , the protection plate 41 is a flat disc structure. The outer diameter of the protection plate 41 is equal to the outer diameter of the ceramic outer ring 1, and the inner diameter of the protection plate 41 is equal to the inner diameter of the ceramic inner ring 2. The limit block 42 and the protection plate 41 are fixedly connected. The number of the limit blocks 42 is four times the number of the protection plates 41.
