shaft bearings by rolling vibration

When the operation of the bearing under a radial load, its internal only a plurality of rolling load, due to the ferrule elastic contact constitute the "shaft bearings" supporting the rolling body in the radial load line generates periodic oscillation, and the shaft center will therefore vertically moving or moving horizontally, and causes noise. This kind of vibration is called rolling through the vibration, especially in low speed when the more obvious.

And the amplitude is related to bearing type, radial load, radial clearance and ball number. Usually the smaller amplitude, if the amplitude is large when the harm, this is often the minish preload appropriate axial clearance or to reduce.
