About 40% of the failure of ball micro bearings is caused by dust, dirt, debris pollution and corrosion. Pollution is usually caused by incorrect use and poor operating conditions. It also causes torque and noise problems. Micro bearing failures caused by the environment and pollution can be prevented, and the causes of such failures can be determined by simple visual observation. As long as the use and installation is reasonable, the denudation of micro bearings is easy to avoid. Denudation is characterized by indentation in the raceway of the miniature bearing ring caused by impact loads or incorrect installation. Denudation usually occurs when loads exceed the material yield limit. Denudation can also occur if the installation is incorrect so that a load crosses the miniature bearing ring. The pits on the miniature bearing rings also generate noise, vibration and additional torque.

Because the reasons for the heating of micro bearings are different, the solutions are different. The following is the solution when the temperature of micro bearings is overheated:

1. Grease filling method, the so-called grease filling method is to fill the appropriate amount of grease to the working surface of the bearing regularly, which is one of the most commonly used grease lubrication methods.

2. Oil cup method, oil cup method is to set a screw cap type oil cup or pressure oil cup on the bearing seat, and rotate the screw cap or oil gun regularly to inject grease. This is also a common way of grease lubrication.

3, pressure grease supply method, pressure grease supply method is to rely on grease pump grease supply. At this time, grease with good fluidity should be selected.

4. Centralized grease supply method, centralized grease supply method through grease pump, at the same time to each deep groove ball bearing and other components. Similarly, at this time, the grease should be selected with good flow, oxidation resistance and corrosion resistance, which is also a pressure grease supply method.
