(1) the resultant force applied should pass through the axis of the bearing as far as possible, which requires the application point to be uniform, symmetrical and stable, and to apply force through the sphere or parallel to the axis.
(2) the size of the force should be stable and uniform, not impact, this requires the use of oil pressure or can be applied to a smooth tension or pressure tools, really have to use hammer strike, but also through the copper sleeve and other relatively soft metal to buffer, striking force as light as possible.It is best to hammer with a copper rod or hammer.
(3) avoid applying force through rolling body, which requires applying force through inner ring when assembling and disassembling inner ring (shaft ring), and applying force through outer ring when assembling and disassembling outer ring).
(4) the drag force should continue to the due degree, such as when the bearing is installed in the correct position to stop the application of force, ensure that the ring (washer) end face against the seat hole or shaft shoulder end face, neither too tight squeeze, and can not be installed in place.
