Although this noise is essentially due to manufacturing errors, it is actually related to the choice of lubricant, the mounting conditions of the bearing, and the accuracy of the shaft and housing. 

 

This kind of noise is divided into two types: cage sound and vibrating sound.

  1.     

  2. 1.The cage sound refers to the periodic vibration and noise emitted by the vibrating cage and the rolling element, which is easy to occur when the pocket is loose and the friction is large.

  3.       

  4. 2.The vibrating sound is noise directly related to the rolling surface waviness of the bearing. This is a pure-tone noise. Its frequency does not change for a constant speed, and its frequency changes with varying speeds.
