Manufacturing process of the deviation caused by vibration, deviation is smaller, the smaller the vibration, roundness, waviness and surface roughness on the surface of the steel ball is the most profound effect on the vibration in the bearing parts, followed by the shape of the inner ring and outer ring channel error and surface roughness, again is bearing cleanliness and lubricant, such as quality operation conditions such as the installation conditions, speed, Axial load direction, magnitude, etc.

Bearing fatigue failure is a failure of the surface form, mainly manifested as fatigue crack initiation, propagation and fracture process, under the alternating load produced by the failure of the long-term impact of the metal. The cracks are in two ways:

The first: On the surface, this is in the process of rolling contact bearings, due to the work in the plastic deformation and strain hardening on the surface of the contact stress on the surface of the cyclical changes caused by the effect of external load, and finally on the inner surface of the small crack from the development, the formation of surface crack between the two, because Xie into the lubricant on the surface of the work, the power of the open, crack down on the wall, Force the crack forward;

Second: from the surface layer, repeated pressure, surface contact, initially in the exposed surface of the place a certain depth of crack crack, and along the surface direction of the Angle, to a certain depth, from the surface of the contact surface, and beyond the surface, and eventually formed erosion stripping, leaving a horse pit.
