FAG import bearing rust - bearing knowledge and maintenance method

NSK bearing rust prevention and maintenance method 1, soaking method: NSK bearings by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil. The temperature of the oil film thickness can be controlled by anti-rust oil or viscosity to achieve. 2, brush method: used for soaking or spraying NSK bearings or not apply special shape bearing, brush should not only pay attention do not produce rust-proof oil accumulation, also should pay attention to prevent leakage. 3, spray method: some large NSK bearing cannot be oiled by soaking method, generally about 0. 7 mpa pressure filtering compressed air spraying where clean air. Spray method used solvent XiShiXing rust-proof oil or thin layer of anti-rust oil, but must use perfect fire protection and labor protection measures. The influence of the purity of the bearing NSK bearing life of a considerable, we have the specialized test, the result is the difference for several times or even dozens of times. The higher the purity of the bearing, the longer service life test showed that different cleanliness of lubricating oil had a great influence on the ball bearing life. So, to improve the purity of the lubricating oil can prolong the life of NSK bearings, in addition, if the lubricating oil containing dirt particles control under 10 um, bearing life is growing into 7 times. 1, the vibration impact our test center of the test results show that the cleanness of the serious influence bearing vibration level, especially the vibration of the high frequency band. High cleanliness of low vibration velocity values, especially in high frequency band. NSK bearing grease 2, for the influence of noise on the dust test, the influence of noise had done to prove the more dust noise is larger. 3, affect the performance of lubrication NSK bearing cleanliness, not only affect the formation of lubricating film, still can cause the deterioration of the grease and accelerate its ageing, thus affecting the grease lubrication performance degradation. 1. Imported bearing if get good lubrication, and cut off the right moisture and debris, said oil seal should not wear. However, best when open the bearing box, check the bearing and periodically check the oil seal. Check of the condition of the near the bearing oil seal, in order to ensure that they are enough to prevent hot liquid along the axis of infiltration or corrosive liquid or gas bearing, oil seal if already wear should be replaced as soon as possible. 2. High temperature often said bearing is in abnormal situation. High temperature also harmful to within the bearing lubricant. Sometimes could be blamed on the imported bearing overheating bearing lubricant. If the bearing in more than 125 degrees Celsius temperature operation for a long time, can reduce import bearing life. The causes of high temperature import bearings include: insufficient lubrication or excessive lubrication, lubricants containing magazine, heavy load, bearing damage, clearance, and the oil seal of high temperature and friction and so on. 3. Check the status of the operation of the machine, monitoring, lest cause the equipment downtime. 。
