Insert the tapered cylinder 4 so that it passes through the inner wall of the tapered cylinder 4 and is slowly guided to align with the inner wall of the inner ring 1 to achieve positioning. During the insertion process, the shaft will squeeze the oil-absorbing sponge layer 6 to lubricate the shaft and the tapered cylinder 4 with the lubricating oil, thereby reducing the friction between the shaft and the inner wall of the tapered cylinder 4 and increasing the service life of the tapered cylinder 4. When the bearing composed of the inner ring 1 and the outer ring 2 is in use, the inner ring 1 and the outer ring 2 are covered by the dust cover ring 10 in the groove 9 to prevent dust from entering the interior.
