Hunan Jintai Hardware and Machinery Co., Ltd. describes the use of oil-free bearings in the process of application, inevitably to install and disassemble, in order to ensure the re-use of the bearings, when installing and dismantling the bearings should pay attention to the following points:
     1. The resultant force of the applied force can pass through the axis of the bearing as much as possible, which requires that the force application point be symmetrical and stable evenly, and exert force through the spherical surface or parallel to the axis.
     2. The size of the force should be smooth and even, and there should be no impact. This requires the use of oil pressure or the use of things that can exert a smooth pull force or pressure. When the real hammer has to be selected, it must pass through a copper sleeve and other soft The chipping metal is buffered and the percussion can be lightened. It is best to hammer with a copper or copper hammer.

     3. The drag force should be continued to the required degree. For example, when installing the bearing, stop the force when the bearing is just installed to the exact position, and ensure that the end face of the ferrule (washer) abuts against the shoulder of the seat hole or shaft, both You can't squeeze too tightly, and you can't hold it in place.
     4. To prevent the application of force through the roll body, which requires the inner ring (shaft ring) when installing and dismantling through the inner ring, when the outer ring is installed and removed) through the outer ring force.
