1, low noise NSK bearing installation and adjustment also can imitate the long life bearing the grouping of method, and makes the interference with size is consistent, NSK bearing clearance is relatively consistent, and hope to cooperate with interference in the possible range of take smaller values, in order to ensure that the NSK bearings rolling deformation and small ways, thus roller caused by noise smaller.
2, clearance to noise relationship is very big, NSK bearing is the ideal state when the highest temperature is in motion state, clearance value just is zero. Judge clearance big methods are: static state make bearing axial displacement, the reciprocating big movments, in the works of a large, heavy cloud noise.
3, if the engine of a catch screaming cries of hate, show NSK bearing preloaded too big, bearing biased big preloaded surplus, should relax with prestressing degree. If the clearance is too big, can make two bearing circle along the axial comparatively a little bit: not only reduce clearance, and increase the axial rigidity, can reduce the noise NSK bearings.
4, rolling body into a load in the area of the will be there around skid or dynamic, such already will increase noise can also cause wear, and small clearance and big axial stiffness can eliminate the phenomenon. But clearance can not have small, lest cause the temperature too high and shorten life.
5, and sometimes because the working temperature of host over a large area, or shaft bearing the size of the hole with a discrete, not a the setting is to get a proper clearance, and in this case, may to the NSK bearing outer ring using elastic and the constant pressure preloaded method.
