Although the function of a ball bearing is rotation, they also generate vibration during the rotation. The vibration that is changed by the frequency depending on the speed is called “vibration by forced rotation.”
Calculation of Vibration by Force Rotation in a Ball Bearing
The vibration is generated in the axial, radial, and rotating directions. The vibration can be critical in some applications.
This vibration sometimes causes other parts of the assemblies to resonate as vibration energy is emitted. It is necessary to fully understand the application characteristics in order to select a suitable bearing and its specification.
