The fan bearing, on the drive side, vibrates loudly and loudly after a few days of use. When you open it for inspection, you will find that the balls are damaged, as shown in the picture. Only one ball is damaged at a time, and the track is not damaged. Please help me analyze the reason. Is it current corrosion?

Look at the picture. Have you ever been injured by electric shock? Was electric welding used during installation? Welded ground wire? ? ? Are there any particulate impurities entering it?
