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, and 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. An important factor, if your bearing fails early, then you should quickly check your lubrication method. Insufficient lubrication, or improper selection of lubrication methods will directly reduce the efficiency of bearing use, resulting in bearing failure, etc. Therefore, when selecting grease, it is necessary to comprehensively consider multiple factors such as operating temperature, load, and speed according to different use conditions; Bearing grease is a widely used lubricant, and experienced angular contact ball bearing manufacturers believe that it It is an important factor affecting the bearing life, mainly to reduce friction, heat dissipation, shock absorption, noise reduction, etc. For commonly used bearings, when the working temperature is about 50 ℃, the lubricant should be replaced once a year. 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 contaminants, it must be replaced immediately. The choice of lubricating oil also affects the temperature rise of the bearing. Too much viscosity or too little viscosity is not easy to form an oil film, which can cause the bearing temperature to rise 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. The torque is accurate, in order to turn stable!
