Using advanced installation tools can avoid bearing damage caused by improper tools and operations during installation. For example, when installing bearings, workers used the tapping method of copper rods, which could easily cause uneven axial stress on the bearings, cause deformation of the cage, damage to the rolling elements, and increase in clearance. In addition, during the tapping process, the copper rods Copper powder flies into the bearing cage, which can easily cause bearing failure.
