FAG bearings vibration is due mainly due to the FAG bearing rotation, under the action of load and deformation of FAG bearings to cause vibration.　　
1 bearing vibration　　
FAG bearing vibration was basically caused by the vibration of the bearing rings, and bearing structure, rigidity, precision of manufacture, installation conditions and usage, and other factors. If the bearing inner ring raceways have a larger radial corrugation, which have a radial vibration ring rotating bearing outer ring.　　
Bearing within ring of corrugated not only will caused outer ring of radial vibration, and also will caused outer ring of axis to vibration, bearing in by axis to load Shi on will make bearing within, and outer ring of axis to relative location occurred change, therefore in within ring turned Shi bearing outer ring also on produced has axis to vibration mouth Shaker in work Shi, for high-speed turned of bearing for, due to corrugated caused of vibration frequency, has may is equal to stress vibration Manager axis of turned frequency, that produced resonance.
2 cage vibration　　
Vibration of cages, mainly due to bearing and vibration of rotating cage of rolling impact vibration of each other.　　
Shaker work, accompanied by alternating load impact load, will cause the cage of high vibration, this vibration is generally believed that, due to sliding friction between the rolling elements and cage-induced self-excited vibration of cages.　　
Main cage vibration in ball bearings and tapered roller bearings, radial clearance is too large, poor lubricating properties, vibrating vibrator shaft torque fluctuation on cases likely to occur.
3 rolling body vibration　　
In a large ball bearings and roller bearings for vibrating screen, when the main radial bearing load and low speed rotation, will have a drop of rolling vibration.　　
Experiments found that when the bearing under radial load and oil poor performance cases, the operation will initially hear "click \ click" sound and vibration, this is mainly due to the rolling elements in the sudden acceleration after leaving the loading area collided with the cage made of sound and vibration, this crash is inevitable but the operation will disappear after some time.
When subjected to radial impact load bearings in vibrating screen works, only within it a number of rolling elements to withstand loads due to elastic contact of races consisting of "Spring" support for scrolling by line radial loads produce cyclic vibrations (Center of hinge will move vertically or horizontally from top).　　Especially in the Shaker vibration frequency is low, this type of vibration performance becomes more apparent.
4 friction vibration　　
Mainly refers to abnormal vibration of FAG bearings friction vibration, friction and vibration on large ball bearing easy in General, using grease lubrication in particular easier to occur when grease lubrication is not good. Based on experiment and observation, FAG bearings often rub vibration and oil is directly related to nature.　　When poor lubricant performance or unclean, are prone to friction and vibration, but also associated with the outer raceway of processing quality of FAG bearings, if this is used special precise machining method, will be able to better control the friction and vibration.
FAG bearing vibrations tend to be more the result of a combination of vibration. Tests showed that in bearing operation under normal conditions, bearing surface waviness is the main factor causing vibration.
