The failure reason of miniature bearings

The failure of the ball in the flanged ball bearing in about 40% are caused by dust, dirt, debris pollution and corrosion. Pollution is usually caused by incorrect use and poor use environment, it also causes torque and noise problems.
Miniature ball bearings produced by the environment and pollution of the failure can be prevented, and observed by the naked eye is simple can determine the production of this kind of failure reason. As long as the use and reasonable installation, denudation of miniature bearing is easy to avoid. Erosion is characterized in miniature bearing ring raceway on the left indentation produced by impact load or incorrect installation.
Erosion is usually occurs in the load exceeds the yield limit of material. If not installed correctly so that a load across the miniature bearing ring will produce erosion. Miniature bearing ring on the pressure pit will produce noise, vibration and the additional torque.
