The positioning blocks 8 are arranged in an equiangular array with the same center of the circle. The positioning blocks 8 slide inside the guide chutes 9. This arrangement enables the rollers 3 to move relatively inside the inner bearing ring 2 and the outer bearing ring 1 when the inner bearing ring 2 and the outer bearing ring 1 rotate relative to each other. At this time, the positioning blocks 8 will slide relatively inside the guide chutes 9, so as to stably position the sealing ring 7 without affecting the use of the outer bearing ring 1 and the inner bearing ring 2; the sealing rings 7 are arranged on both sides of the inner bearing ring 2 and the outer bearing ring 1. The sealing rings 7 are rotatably connected to the inner bearing ring 2. This arrangement enables the gap between the outer bearing ring 1 and the inner bearing ring 2 to be blocked, so that impurities are not easily introduced into the inside of the hub bearing; the rollers 3 are arranged between the outer bearing ring 1 and the inner bearing ring 2. The outer bearing ring 1 and the inner bearing ring 2 are rotatably connected. This arrangement enables the outer bearing ring 1, the inner bearing ring 2 and the rollers 3 to be positioned, so that the outer bearing ring 1, the inner bearing ring 2 and the rollers 3 can cooperate for use.
[0028] Working process: The bolt 6 passes through the first screw hole 5 and the second screw hole 10 to position the mounting block 4 on both sides of the outer bearing ring 1. The mounting block 4 arranges the sealing ring 7 on both sides of the outer bearing ring 1 and the inner bearing ring 2, so as to block the gap between the outer bearing ring 1 and the inner bearing ring 2, making it not easy for impurities to enter the inside of the hub bearing, reducing the occurrence of the situation that impurities enter the inside of the hub bearing and affect the use of the hub bearing. When the inner bearing ring 2 and the outer bearing ring 1 rotate relative to each other, the rollers 3 move relatively inside the inner bearing ring 2 and the outer bearing ring 1. At this time, the positioning blocks 8 will slide relatively inside the guide chutes 9, so as to stably position the sealing ring 7 without affecting the use of the outer bearing ring 1 and the inner bearing ring 2.
