1), bearing a material fatigue phenomenon from the start using the guide, this period is the length of the speed and bearing, the size of the load, lubrication cleanliness relationship.

2), fatig ue load surface shear stress periodicity formed after a period of time, these shear stress caused a small crack skull, and then gradually extend to the surface, when rolling after these split skull, then some split block off, forming the so-called "peeling phenomenon", then continue to expand with the stripping, bearing damage unusable. china bearing manufacturer

3) above, bearing the description of fatigue, which was originally below the surface, although the initial peeling usually very slight, but with the increase of stress and the increase of the crack block, resulting in the peeling area of ​​spread, the damage situation usually maintained for a long period of time, the stage is visible in the increase in noise and vibration.

4) bicycle bearing the initial stage of damage, it may only rotation is difficult to feel, and the sense of pit ting late discovery rotation, a sense of pitting, the bearings are not can not be used, but in each forward beads and bowls and shaft profile to greater wear and more serious damage, because the bike is a low speed and high pressure type bearing, so even if the surface stripping is serious, nor is it unusable, but an invisible silent drain your power, your feelings may only feel that the car does not know why bad riding ring true. bearing manufacturers

5), before the complete destruction of the bearing, it provides users found enough time, do not ignore the existence of such a friction, it will make the ride slowed down, so that greater consumption of long-distance physical slower.
If the surface roughness is fine, if the lubricant film with appropriate thickness, then the probability of surface stress generated very low, which is why the appropriate choice oil suitable for lubrication reasons, however, if the pressure load over film pu value (fatigue load limits, such as excessive speed, high pressure shock), the fatigue of the material will come sooner or later. bearing suppliers
