(1)   The force as much as possible through the bearing axis, which requires a springboard for symmetrical and smooth, spherical or parallel to the axis by force.


(2) The force should dictate the size of the stable and uniform, not a shock, which requires the use of oil pressure or tension or pressure can exert a smooth tool, when it had to use hammer, but also by relatively soft copper sleeve, etc. not off the scrap metal to be buffered, as percussion force. The best is to use copper bar or copper hammer to hammer.

(3) to avoid through the rolling force, which requires the assembly and disassembly inner ring (shaft washer) through the inner force, when the outer ring assembly and disassembly) by outer force.

(4) The drag force due to continue until the extent of, for example, when installing the bearing mounted in bearings just the right position to stop the force to ensure the ring (gasket) arrived by the end of the housing bore or shaft shoulder block face, neither packed too tight, they can not be installed in place.
