This is a simple way to install small and medium-sized bearings. When the inner ring of the bearing is tightly matched and the outer ring is relatively loose, the copper rod is pressed against the end face of the inner ring of the bearing, and the copper rod is directly hit with a hammer, through which the force is transmitted, the bearing is slowly mounted on the shaft. When the inner ring of the bearing is large, the copper rod can be used to knock evenly around the end face of the inner ring of the bearing. Do not knock on one side or too hard. It should be symmetrical and gently knocked on slowly, so as not to load the inclined crack self-aligning roller bearing.

The use of sleeve installation method and the use of copper rod installation of self-aligning roller bearing truth is the same. It is to press the sleeve directly on the bearing end face (bearing mounted on the shaft press the inner ring end face; When installed in the hole of the shell, press the end face of the outer ring), with the hand hammer knock force can be evenly distributed on the end face of the whole ring of the bearing installed, and can be used with the press, the installation is labor-saving and time-saving, and the quality is reliable. The sleeve used for installation shall be of soft metal (copper or mild steel pipe is acceptable). If the bearing is installed on the shaft, the inner diameter of the sleeve should be slightly larger than the journal 1-4mm, and the outer diameter should be slightly smaller than the diameter of the rim of the bearing inner ring, or the thickness of the sleeve should be made equal to 2/3 to 4/5 of the thickness of the bearing inner ring, and both ends of the sleeve should be flat and perpendicular to the barrel body. If the bearing is installed in the hole, the sleeve diameter should be slightly smaller than the bearing diameter.
