Rod end joint bearing installation skills under various conditions

- Oct 24, 2018-

The installation of the rod end joint bearing needs to be operated according to the actual conditions. For example, in the absence or inability to use the press, the rod end joint bearing can be installed with the assembly sleeve and the small hammer. The hammering force should be transmitted evenly to the entire circumference of the end face of the end rod joint bearing ring, so the hammered end face of the assembly casing should be made spherical.


The force required to install a rod end joint bearing is related to its size and the amount of interference that is commonly used, and is commonly used for medium-sized or large rod end joint bearings with large interference. Before hot loading, put the rod end joint bearing or the separable joint bearing ring into the fuel tank or special heater and heat evenly to 80-100 °C, not more than 100 °C.


Hot-fit rod end joint bearings require skilled operation skills. When the bearing is removed from the heating tank or heater, immediately wipe off the oil traces and attachments on the bearing surface with a clean cloth, and then place it in front of the mating surface. Push the rod end joint bearing to the position of the shoulder in one operation. Always tighten during the cooling process or tap the joint bearing with a small hammer through the fitting sleeve to make it tight. When installing the rod end joint bearing, the joint bearing should be slightly rotated to avoid the installation from tipping or jamming.


When the outer ring of the rod end joint bearing and the housing hole are tightly fitted, the housing can be heated and then loaded into the bearing, especially the rod end joint bearing of light metal material, which may be pressed by the outer ring during the tight fitting process. In case of damage to the mating surface, the rod end joint bearing should be heated first.
