When installing, the shoulder of the shaft and the shell is not perpendicular to the mating surface, or the inner and outer rings are skewed due to the bending of the shaft, resulting in excessive contact stress of the rolling surface, resulting in peeling.

Auto bearing manufacturers meet some people because the car wheel bearing installation is not appropriate, and caused the loss, how to remedy it?
1) When installing, the shoulder of the shaft and the shell is not perpendicular to the mating surface, or the inner and outer rings are skewed due to the bending of the shaft, resulting in excessive contact stress of the rolling surface, resulting in peeling.
2) The outer ring is mounted in an oval or tapered bore. When the rolling element through the irregular raceway, will increase the contact stress, resulting in early rolling and rolling the body peeling.
3) Cylindrical roller bearings in the installation, due to the installation of skewed and percussion force over the Ambassador or the outer roll was injured.
4) When the deep groove ball bearings installed in the shaft interference, if the pressure is applied by the outer ring and ball transmission, it is inevitable in the raceway to contact the ball where the pits. These pits are the source of peeling, the rapid development of bearings will soon be scrapped. For this reason, only the inner or outer ring end faces to be mounted can be energized when the inner or outer races are mounted in an interference fit.
5) In addition, the bearing installed too tight, too loose or improper adjustment, can also cause early spalling of the bearing.
