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: 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 cylindrical roller bearing).

Parts of the wave degrees

In the circle of the self-contained bearing shaft or between the secret cooperate, 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

Because of operation or installation errors, small part bearing groove and rolling body might be compromise. 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

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 NSK bearings
The removal of the application from the critical incentive vibration; Or stimulate parts and resonance components resistance between critical incentive vibration; Change the stiffness of the structure, so as to change the critical frequency.
