1, low noise bearing installation and adjustment of grouping method for can also follow the example of long-life bearings, combined with interference more consistent in size, bearing clearance is also more consistent and want to meet the interference wherever possible take smaller value to ensure small deformation of bearing Raceway, to rolling noise caused by smaller.
2, relationship between clearance on the noise of big, ideal State is when the maximum temperature of the bearing is in operation when the clearance values to zero. Judging method of clearance is too large: static axial displacement of the bearing, its larger reciprocating, make a large, low-noise when in operation.
3, if you hate loud shrill cries issued when running, then the bearing preload is too large, bearing a large pre-interference should be slightly relaxed level of pretension. If the clearance is too large, you can make two relatively along the axial bearing rings only slightly, both the clearance increases the axial stiffness, reduces the bearing noise.
4, rolling into the loading zones will skid or Hunt around, this can also cause increased noise and wear, while small clearance and axial stiffness can eliminate this phenomenon. But clearance cannot be too small, so as not to cause overheating and shortened life expectancy.
5, sometimes due to host a large range of working temperature, size of the shaft and housing bore or discrete large, cannot be more appropriate clearance set at a time, in this case, the outer ring of the bearing can be used elastic preload method.
