FAG bearing within the hard disk on the noise mainly comes from the motor of the different components form of exercise, and is able to rotate the wind noise from the aspects of form, from the segmentation, bad column, bearings, bearings and motor magnetic disc is the source of noise, which can only be for ball bearing is nothing too big difference.
But they are always the contact in the high speed makes the ball bearing noise and vibration inevitably.
Sounds in the quiet environment also can let a person feel very uncomfortable, and vibration is always there.
Just think, if 7200 RPM, 10000 RPM products still use ball bearing, so its running noise and vibration generated by the affirmation is unbearable, and the liquid bearing is much better than ball bearings.
Due to the use of highly incompressible liquid lubrication system, to avoid the ball bearing that caused by direct metal to metal contact of the spread of the running noise and vibration.
At the same time, the liquid lubricant can external vibration of attenuation effect, thereby reducing the noise due to vibration.
FAG import bearing not only have a better grasp of the work, is also the same for other terms have a certain understanding, and mechanical aspects of the effect also can better to reflect the effect, so the noise in this area have a better grasp of form, in order to be able to reduce liquid bearing noise, can better control.
In the form of reducing the resonance.
