Talking about: Technology for installing and replacing SKF bearings

     (1) The force of the applied force passes through the axis of the SKF bearing as much as possible, which requires the force application 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 a tool that can apply a smooth pulling force or pressure. When it is necessary to use hammering, it must also be soft through a copper sleeve. It is buffered without falling metal, and the tapping force is as gentle as possible. It is best to use a copper rod or a copper hammer for hammering.
     (3) Avoid applying force through the rolling element. This requires the force applied through the inner ring when the inner ring (shaft ring) is removed or removed, and the force is applied through the outer ring when the outer ring is assembled or removed.
     (4) The drag force should be continued to the extent that it should be, for example, when installing the bearing, stop the force when the bearing is just in the correct position, and ensure that the end face of the ferrule (gasket) abuts against the seat hole or the shoulder end face of the shaft. Can not be squeezed too tightly, and can not be installed.
