Embodiment 1
[0088] as attached figure 1 , inner dust cover and outer dust cover double dust-proof sealing structure oil-free lubrication rolling bearing, the bearing is a deep groove ball bearing, including outer ring 11, inner ring 12, ball 13, retainer 14, inner dust cover 15 and The outer dust cover 16, the rib of the inner ring 12 is processed with a dust cover installation groove, the inner dust cover 15 is installed in the installation groove, and there is a gap between the sealing end of the inner dust cover 15 and the outer ring 11; The outer dust cover 16 located outside the inner dust cover 15 is installed on the mounting groove of the outer ring 11. There is a gap between the sealing end of the outer dust cover 16 and the inner ring 12, and the inner metal dust cover 15 rotates relative to it. A radial non-contact seal is formed between the outer ring 11 of the outer ring 11 and between the outer metal dust cover 16 and the inner ring 12 which rotates relatively therewith.
