[0028] Inner ball groove 2 is arranged in the inside of bearing outer ring 1, for assisting steel ball rolling, and the inside of inner ball groove 2 is provided with deep groove steel ball 3, the outside of deep groove steel ball 3 is provided with first retainer 4, first retainer 4 is penetrated by double-headed bolt 5, and one end of double-headed bolt 5 is movably connected with second retainer 6;

[0029] The outer positioning groove 7 is provided on the outside of the bearing outer ring 1 for assisting the axial positioning of the bearing, and the inner movably connected with the adjusting ring block 11 of the outer positioning groove 7, and the outer ring sleeve 12 is fixedly installed on the outside of the adjusting ring block 11. The inner part of the outer positioning groove 7 is provided with a fixing groove 13, and the inner part of the fixing groove 13 is fixedly installed with a damping telescopic spring 14. The top of the damping telescopic spring 14 is fixedly installed with a resistance plate 15, and the bottom of the resistance plate 15 is fixedly installed with a positioning rod 16. A positioning column 17 is fixedly installed above the resistance plate 15. The positioning rod 16 can be pulled from the inside of the bearing outer ring 1. Since the top of the positioning rod 16 is connected to the resistance plate 15, when the positioning rod 16 is pulled, the resistance plate 15 synchronously compresses the damping telescopic spring 14 to pull the positioning column 17 to the inside of the outer positioning groove 7. At this time, the positioning column 17 is separated from the outer ring sleeve 12. The steering adjustment can be completed by rotating the direction of the bearing outer ring 1 through the outer positioning groove 7 and the adjusting ring block 11.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, the first retainer 4 is threadedly connected to the second retainer 6, and the deep groove steel balls 3 are distributed in an annular array on the inner ball groove 2. The first retainer 4 and the second retainer 6 fix and separate the internal deep groove steel balls 3 from both sides, thereby improving the smooth operation and life of the bearing. A fastening bolt 8 runs through the interior of the bearing outer ring 1, and one end of the fastening bolt 8 is movably connected to the bearing inner ring 9. An outer closing plate 10 is provided on the outside of the bearing outer ring 1.
