In general, the SKF bearings in the rolling bearing itself does not produce noise. Usually feel "bearing noise" in fact, the vibration of the sound effect of SKF bearings directly or indirectly with the surrounding structure.
This is why many times the noise problem can be regarded as related to the vibration of the bearing application. Arising as a result of the loaded rolling element number of changes in excitation when a radial load to load on a bearing, load bearing rolling element number in the operation of a slight change will cause the offset of the load direction. The resulting vibration is inevitable, but can be mitigated through the axial pre-load, load at all the rolling element (not applicable to SKF bearings, cylindrical roller bearings).

The wave of components in the case of the close tie between the bearing ring and the bearing or drive shaft, the bearing ring may be deformed shape to match adjacent parts. If the deformation, in operation it may lead to vibration. Therefore, the bearing and the shaft is machined to the required tolerance is very important.angular bearings

Local damage due to the operation or installation errors, the small part of the bearing raceway and rolling element may be damaged. Running, rolling across the damaged bearing components will generate a specific vibration frequency. Frequency analysis to identify the damaged bearing components. The vibration behavior of applications in many applications, the bearing stiffness and the stiffness of the structure around the same. This feature to correctly select the bearings (including pre-load and clearance) and its configuration in the application, it is possible to reduce vibration applications.roller ball bearings

There are three ways to reduce the vibration of the SKF bearings:
One remove from the application of the critical excitation vibration.

Suppressing resistance to stimulate critical excitation vibration parts and resonance between components.angular contact bearings

Change the stiffnes s of the structure, thus changing the critical frequency.
