Many people think that the early failure of angular contact bearings should be related to the raw materials and processing technology of angular contact ball bearing manufacturers. They often overlook the more important point that the lubrication method of angular contact ball bearings is also an important factor for the early failure of bearings. Important influencing factor, if your bearings fail early, then check your lubrication method as soon as possible. Insufficient lubrication or improper selection of lubrication methods will directly reduce the service efficiency of the bearing and lead to bearing failure. Therefore, when selecting lubricating grease, it is necessary to consider multiple factors such as operating temperature, load, and rotating speed according to different usage conditions; bearing grease is a widely used lubricant, and experienced angular contact ball bearing manufacturers believe that its It is an important factor affecting the life of the bearing. It mainly plays the role of reducing friction, heat dissipation, shock absorption, and reducing noise. For commonly used bearings, the lubricant should be replaced once a year when the working temperature is about 50°C. If the operating temperature is 100°C or higher, even if its thermal stability is good, the lubricant should be replaced at least every three months. If the oil bath lubrication becomes water or foreign particles become contaminating substances, it must be replaced immediately. The choice of lubricating oil also has an impact on the temperature rise of the bearing. If the viscosity is too large or the viscosity is too small, it is not easy to form an oil film, which will cause the temperature rise of the bearing to be too high. Especially when the viscosity of the lubricating oil is high, it not only increases the internal friction between the lubricating oil molecules, but also increases the friction between the oil and the metal, thus generating too much heat. Only when the torque is accurate can the rotation be stable! (/jjcqzc1150.html)
