The cause of micro miniature bearing failure and the solution to overheating of temperature.

Failure reason of micro miniature bearing

About 40% of the failure of micro miniature bearings is caused by dust, dirt, debris and corrosion. Contamination is often caused by improper use and poor use of the environment, and it can also cause problems with torque and noise. The micro miniature bearing failure caused by the environment and pollution is preventable, and the cause of such failure can be determined by simple visual observation. As long as it is used and installed properly, the ablation of the micro miniature bearing is easily avoided. The ablation feature is characterized by the presence of indentations on the micro miniature bearing raceway caused by impact loads or incorrect mounting. Denudation usually occurs when the load exceeds the yield limit of the material. If the installation is not correct, a certain load will erode across the micro miniature bearing ring. The craters on the miniature bearing rings also generate noise, vibration and additional torque.

Because the micro miniature bearing has different causes of heat generation, the solution is different. The following is the solution for the temperature reduction of the micro miniature bearing:
1. The micro-capacity filling method, the so-called fat filling method is to regularly fill the micro miniature bearing working surface with a proper amount of grease, which is the most commonly used grease lubrication method.
2, micro miniature bearing oil cup method, the oil cup method is to set a cap-type oil cup or pressure oil cup on the bearing seat, periodically rotate the cap or use a grease gun to inject the grease. This is also a common way of grease lubrication.

3, micro miniature bearing pressure supply method, pressure supply method is based on grease pump grease. At this time, a grease with good fluidity should be used.
4, micro miniature bearing centralized grease method, centralized grease supply through the grease pump, while providing grease to each deep groove ball bearing and other components. Similarly, the grease should be greased with good flow, oxidation resistance and corrosion resistance. It is also a pressure supply method.
