Be injected with seal oil fat in the slit that forms between bearing 4, seat seal ring 5, sealing cover 6, interior catch 7 and the outer gland sealing ring seat 8;

Seat seal ring 5, sealing cover 6 and interior catch 7 are made by plastic polymer;

Outer gland sealing ring seat 8, seal cap 9, baffle ring 10 and circlip for shaft 11 are made by steelwork.

The utility model has substantive distinguishing features and progressive with respect to prior art, specifically, has following beneficial effect: 1, adopt " hard and soft " double sealing structure, it is further perfect that dust seal performance, immersion sealing property, trickle sealing property are obtained, and reached the continual and steady needs of producing under extremely abominable production environment; 2, adopt " hard and soft " double sealing structure, make the long service life of carrying roller, result of use unanimity under various environment, damage rate is extremely low in normal the use, can exempt the trouble of maintain and replace and lower productive costs, reduces labour intensity; 3, carrying roller bulk strength height, shock resistance, collision ability are strong; 4, can eliminate or reduce accident potential, improve safety performance; 5, can repeat maintenance and use, reduce waste; 6, improve the smoothness of operation of main frame, reduce the shake of material and glide.
