FAG bearing eccentric and housing/abutment process deviations

FAG bearings eccentric will shorten bearing life and reduced service life depends on the degree of eccentricity. In order to give full play to bearing service life, base of support bearings and abutments must be in bearing eccentric within the limits provided by the manufacturer. If eccentric level exceeds the limit, the FAG bearing the bearing load will not work as expected along the rolling element and the Raceway are allocated, but instead will focus on the rolling elements roll, spheres, or one of the local area road. In the case of extremely eccentric or angular offset, load into the edge of the rolling elements and raceways. Local load serious concentration and high stress can lead to premature fatigue of metals.
Eccentric causes:
Processing imprecise or wear of bearings or shafts
The offsets generated under high load
The abutment on the shaft or housing skew
