Bearing a rotation of the inner ring and the outer ring raceway, the rolling contact with the rolling body is thus running track as a dark surface, the running track is attached to the raceway surface is not abnormal, whereby the change can be learned load conditions, so remove the bearing case, strict attention and observed trajectory raceway. If you look closely the running track will be informed that only bear radial load to bear large axial load to withstand the torque load, or and extreme rigidity inequality on the bearing housing.
You can check the bearing is coupled with the unexpected load and installation errors whether NUS, and investigated the causes of bearing loss for clues.
If no errors and the correct use of the words, prior to the bearing life, but with a very long period of time, in this case, the damage state of peeling. On the other hand, there are unexpected early injury, and stand up to the early damage as the reasons for the early damage, use and lubrication is not enough to consider, and thus there is a foreign body penetrated, the error bearing assembly and shaft deflection enough of the shaft and bearing box.
It can be said, more overlap, the situation of these reasons. Therefore, to fully understand the bearings used machine, use conditions, the bearing peripheral structure on the basis of, if you can figure out the situation before and after the accident, and then combined with bearing damage and a variety of reasons to inspect, we can prevent similar accidents from happening again.
