NSK bearings in order to ensure the long life, can not meet the requirement from general installation and adjustment, and should focus on the following several steps: (
1)
NSK bearings will be according to the interference fit the size of the surface groups, each group will be bearing clearance size according to its sequence.
The corresponding shaft or hole diameter, the same group.
The interference fit surface size of bearing with large diameter shaft group or a hole set corresponding matching, and the small size and small diameter matching corresponding group.
In each of the corresponding set of matching, to get tighter NSK bearing clearance big, little NSK bearing clearance is a loose fit.
Such matching results, in the same batch of installation of the machine, the interference fit is more uniform NSK bearings, neither too loose, but also tight, clearance is relatively uniform, NSK bearings after installation to ensure prestressed fitting, and avoid peristalsis, ring throwing, burst, due to the improper clearance and the shock, vibration or fever, such as well as the occurrence of abnormal bearing failure.
(
2)
At the ends of the supporting shaft neck and coaxial degree of hole and the end of the bearing perpendicularity to guarantee strictly, prevent the formation of the additional load.
If possible, mechanical components should be the role of outside load bearing NSK bearing a little away from that end of the damaged more easily, at the same time axis and the rotating system to smooth operation as soon as possible.
