When removed from the bearings or wheel hub in the outer ring of improper operation or injury will make burrs or bumps on the base of the outer ring. If using the tools in the process inadvertently housings chisels for the mounting surface injuries, you dig a ditch near the region will rise. If these bumps do not even before the reinstall FAG bearings outer ring or grind, influence the bumps through outer ring inner surface of the outer ring, making it correspondingly convex plaque. When rolling impact these raised areas, increased stress, leading to premature fatigue of FAG bearings.
1, the FAG bearings wear, causing the bearings in the process loose tie, resulting in wear. Results occurred spherical roller bearings outer ring metal tear, wear and tear.
2, mismatch created typical of frictional corrosion. FAG bearings load of the bearings and its base in circumstances of relative displacement, resulting in the wear and corrosion.
3, the outer ring on the outer scars were caused by bumps on the housing. And in addition circle on the outer scars correspond to the outer ring raceway, spalling occurs here.
4, due to the split housings cusps on the stress concentration, causing partial flaking occurs on the outer ring raceway.
