1. Where the press is lacking or cannot be used, the end rod joint bearing can be installed with an assembly sleeve and a small hammer. The hammering force should be evenly transmitted to the entire circumference of the end surface of the end rod joint bearing ring, so the hammered end surface of the assembly casing should be made into a spherical shape.
2. The force required to install the end rod joint bearing is related to the size of the joint bearing and the size of the matching interference. For medium or large joint bearings with large interference, the hot mounting method is commonly used. Before hot assembling, put the end rod joint bearing or detachable joint bearing ring into the oil tank or special heater to evenly heat to 80-100°C, not more than 100°C.
3. Hot-fit joint bearings require skilled operation skills. After the joint bearing is taken out of the heating oil tank or heater, immediately wipe off the oil and attachments on the joint bearing surface with a clean cloth (note that cotton yarn cannot be used), and then place it in front of the mating surface. The joint bearing is pushed to the position against the shaft shoulder. Always push tightly during the cooling process, or use a small hammer to tap the joint bearing through the assembly sleeve to make it tight. When installing the end rod joint bearing, the joint bearing should be rotated slightly to avoid overturning or jamming during the installation.
4. When the outer ring of the end rod joint bearing is tightly fitted with the shell hole, the shell can also be heated and installed into the joint bearing. In particular, the joint bearing of light metal materials may damage the mating surface due to the pressing of the outer ring during the tight fitting process. In this case, the end rod joint bearing should be heated first.
