Generally speaking, the rolling bearing SKF bearing itself does not produce noise. Usually feel "bearing noise" in fact is SKF bearing directly or indirectly with the surrounding structure the vibration of the sound effects.

This is why many problems when noise can be seen as the bearing applications involving the problem of vibration. For loading roller from the quantity change excitation when a radial load in a bearing, the bearing load of roller in operation of the number a slight change, namely: the 2-3-2-3... This caused the load of the direction of migration. The resulting vibration is inevitable, but through the axial preload to alleviate, loading in all rolling elements (not for SKF bearing of cylindrical roller bearing).

Parts of the wave degrees in the self-contained bearing circle or between shaft with dense, bearing circle may with adjacent components combined the shape of the deformation. If appear distortion, the operation of the vibration may be. When, therefore, the bearing and the shaft machined to the required for the tolerance is very important.

Local damage due to operation or installation errors, small part bearing groove and rolling body might be compromised. In the operation, rolled the damaged bearing parts can produce a particular vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. Applications of vibration behavior in many applications, bearing stiffness and around the same structure stiffness. Because of the characteristic, as long as the correct choice of the bearing (including the load and clearance) and its application in the configuration, it is possible to reduce the vibration of the application.

There are three ways to reduce the vibration of the bearing SKF: 1. Remove from the application of critical incentive vibration.

2. Or stimulate parts and resonance components resistance between critical incentive vibration.

 
3. Change the stiffness of the structure, so as to change the critical frequency.
