FAG import bearing friction resistance bearing maintenance and lubrication - bearing knowledge

FAG bearing friction resistance of the bearing of the proper lubrication for them successfully working is vital. For ordinary or sleeve bearing, there are different in the different practice principle. In order to make the maintenance of anti friction bearing, it is necessary to understand and use these principles. After fully understand these principles, you should have a key consideration. The characteristics of the lubricant, especially the characteristics of the grease, not's enough only based on the specifications to determine '. Specification only in general terms to physical, a product may include chemical instructions. The most telling, but almost no association with practical specifications. All FAG bearing friction resistance of the bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation. These types are in use is divided into many types. Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement. FAG bearing friction resistance in the bearing type: anti friction bearing is divided into two main types. They are ball bearing and roller bearing. At the same time we also want to know, because of the specific use of different manufacturers and bearing, according to the basic structure and evolution of many different kinds. Lubrication function: resistance to friction lubricant has the following main function 1. Retainer and lubricating bearing sliding contact between other parts. 2. Lubricate seat and not really any contact between the rolling roll. 3. Lubrication between the roller and guide in roller bearing sliding contact. 4. Lubricated bearing all the real rolling contact. 5. Protect highly delicate surface from corrosion. 6. The defense of seal cover foreign material. Grease a magnetic function. 7. To provide a thermal conductivity ( Cold) The means. Lubrication oil in bearing lubrication oil resistance to change is composed of the following factors: FAG bearing design and load; Oil viscosity, the dosage and the speed of the bearing. Just when the dosage of the oil in the friction torque when the minimum contact surface to form a layer of film. But too much oil, the oil viscosity is high friction increases. Lubrication, however, to maintain the security and pay little attention to the desire of the friction loss, usually by a majority of advantage. This means that more oil, usually more heavy oil, will be used to reduce or leakage losses due to evaporation. In general, however, should remember is overloaded bearing and low-speed bearing heavy oil is usually required. Light load and high speed bearing need lighter oil. For anti friction bearing with grease lubrication in filling grease, may not need to use the theory of high pressure, unless very careful to use. High pressure can damage the bearing, waste grease, excessive grease caused by high temperature dangerous and surrounding the FAG bearing invisible environment. In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of bearing capacity. Beyond the amount of usually will be sealed shell discharge and waste. In practice, it is necessary to use there is more than the recommended amount of grease. When the required torque low, only very few can finish of FAG bearing grease lubrication. When the speed is very low and bearing exposure in dust or moisture, bearing might almost be filled. Bearing under the condition of high speed and high temperature usually need more frequent than in general lubrication. Store in a clean container grease. With a clean pulp or inject grease to FAG bearing grease gun. Keep on the grease container sealed. Bearing grease can't too full. Lubricant will ever filling full bearing box, absorb dirt and cause trouble. Too much lubricant will also cause bearing overheating. This phenomenon is especially likely to happen during the high speed shaft - — Lubricant turn cause overheating.
