Hunan Jintai Hardware and Machinery Co.,Ltd. introduces oil-free bearings in the process of operation, inevitably to be assembled and disassembled, in order to ensure the secondary use of bearings, the following points should be noted when assembling and disassembling bearings:
      1. The force of the force can pass through the axis of the bearing, which requires the force point to be uniformly symmetrical and stable, and the force is applied through the spherical surface or parallel to the axis.
2. The size of the force should be smooth and uniform, and it is not suitable for impact. This requires the use of oil pressure or something that can exert a smooth pulling force or pressure. When it is necessary to use hammering, it must also be soft through the copper sleeve. The chipping metal is buffered and the tapping force can be lightened. It is best to use a copper rod or a copper hammer for hammering.
3. The drag force should continue to the extent it should be. For example, when the bearing is installed, the force should be stopped when the bearing is just in the correct position, and the end face of the ferrule (gasket) is abutted against the seat hole or the shoulder end face of the shaft. Can't be squeezed too tightly, and can't be put in place.
      4. Prevent the force from being applied through the tumbling body. This requires the force applied through the outer ring when the inner ring (shaft ring) is applied and detached, and the outer ring is applied.
