In daily use and the purchase of imported bearings always encountered some technical problems, today's technical staff sinda explain to everyone falling body FAG rolling bearing analysis of the sound. The noise under normal circumstances, most appear in the low-speed and radial load bearing FAG bearing large. Since the bearings in the large-scale, then if we do not grasp this method may lead to unnecessary loss. Now to analyze bearing FAG rolling sound of the falling body.

When the bearings in the radial load operation, load bearing areas and non-loading areas, if the bearing has a certain radial clearance, the non-load roller area with no contact with the raceway, but the role of the centrifugal force may be with the outside contact circle, to that end, in the low speed, when the centrifugal force is less than body weight when scrolling, scroll down and experience within the Rolling Road or the collision Cage bearings and stimulate the inherent vibration and noise, and has the following characteristics:
1. In a certain range of different sizes also have a bearing and its speed range are also different.
2. For radial load only the role of radial clearance and also easy to produce larger.
3. May be continuous sound may be intermittent sound.
4. Resin when lubricated easily, not easy to produce when oil lubrication. When it easier for low-grade grease generated when.
5. Frequently occur in winter.
6. The forced vibration to stimulate the outer ring of the second-order regular, third-order bending vibration and thus the issue of the noise. Through the use of pre-load method can effectively reduce the noise, reduce the capacity of the work after the radial bearing clearance, a good selection of lubricant can be improved, and some foreign businesses to use a light roller, such as hollow ceramic roller or roller technology measures to prevent the emergence of such a noise.

Hope that through the technical staff of the FAG rolling bearings falling body on the analysis of sound for everyone to use in the bearing to provide some help.
