Can not be used when the above two types of low-noise bearing noise can be relatively small bearings. The specific comparative basis is as follows:slewing ring bearing
1) Ball bearing noise lower than the roller bearing, the relative slidin g (friction) of less bearing noise is lower than the relative sliding more bearings;
2) using entity cage bearing noise is relatively low than using the punch holder mosaictype solid lubricant bearing; plastic cage bearing noise ratio using the above two holder bearings are low; ball number, outer thick, and the noise is also smaller,
3) high precision bearings, especially with higher precision rolling element inlaid solid lubricating bearings, its noise than the low precision bearing noise is relatively small,
4) small bearing noise than a large bearing noise is relatively small.industrial bearings
