Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1, fig. 2 and fig. 3 in combination, wherein fig. 1 is a schematic structural diagram of a low-wear high-load bearing ring according to a preferred embodiment of the present invention; FIG. 2 is a cross-sectional view of the outer ring of FIG. 1; fig. 3 is a schematic structural view of the dustproof assembly shown in fig. 1. The utility model provides a bearing ring of low wearing and tearing high load, includes outer lane 1, and the internally mounted of outer lane 1 has dustproof subassembly 2, and the quantity of dustproof subassembly 2 has two, and the outer wall spraying of outer lane 1 has sand blasting coating 3, and the outside electroplating of sand blasting coating 3 has electroplating coating 4, and electroplating coating 4's external fixation has retainer plate 5.

The dustproof assembly 2 comprises a sealing ring 21 arranged on the inner wall of the outer ring 1, the diameter of the outer wall of the sealing ring 21 is equal to that of the inner wall of the sealing ring 21, the sealing ring 21 is made of rubber, and a mounting gap between the outer ring 1 and the inner ring of the bearing can be blocked, so that dust entering the inside of the bearing can be effectively avoided.
