Vibration and noise
The main function of the cage is to evenly separate the rolling elements, distribute the rolling elements equidistantly, and reduce the friction and wear between the rolling elements. If there is no cage, the adjacent rolling elements will be worn due to the large relative sliding speed at the contact.
It is composed of inner ring, outer ring, rolling element and cage. Rolling element is the core component of rolling bearing, which changes the sliding friction between relative moving surfaces into rolling friction.
