Four key points of correct force application in bearing

Four key points of correct force application when assembling and disassembling bearings.
(1) The resultant force of the force shall pass through the axis of the bearing as far as possible, which requires that the force application point shall be uniform, symmetrical and stable, and the force shall be applied through the spherical surface or parallel to the axis.
(2) The force should be applied stably and evenly without impact, which requires the use of oil pressure or tools that can apply stable tension or pressure. When hammering has to be used, it should also be buffered by soft metal such as copper sleeve without chip falling, and the knocking force should be as light as possible. It is best to hammer with a copper rod or hammer.
(3) Avoid applying force through the rolling element, which requires applying force through the inner ring when installing and removing the inner ring (shaft ring) and through the outer ring when installing and removing the outer ring.
(4) The drag force shall be maintained to a proper extent. For example, when installing the bearing, stop the force when the bearing is just installed in the correct position, and ensure that the end face of the ferrule (washer) is against the seat hole or the shoulder end face of the shaft, which can not be squeezed too tightly or installed in place.
