For NSK bearings after installation, please don't rush to start using, should be necessary to check, to ensure the NSK bearings installed correctly or not and the normal use.
So for the correct check NSK bearings have what good method?
NSK bearings first, when after the installation, try the shaft bearing components by hand, and observe the NSK bearing the following situations: 1, both fixed and rotating system whether parts have a collision or interference phenomenon, 2, the rotation of the rotating system is axes flexible block, loose, shot up before and after dynamic phenomenon;
3, NSK bearing inner ring end face is reliably resistance on the shaft shoulder end face, meantime whether occurrence crack;
4, observe whether lubricating oil supply or circulation is normal, whether the clearance of the sealing device is symmetrical, all fasteners are in loose phenomenon.
Secondly.
Also check the rotating precision of NSK bearing rotation system, the axial clearance limit, precision, work, and other necessary inspection program.
Finally, when the above proved all normal, check the project can be started to use, but if I found any abnormal signs, should immediately stop using and troubleshooting.
