Introduce FAG choose some matters needing attention of cylindrical roller bearing grease

The best conditions in order to better play FAG bearing, cylindrical roller bearing grease choice is good or not directly related to the stable operation of the equipment. Bearing grease must consider from the following aspects: the choice of rust inhibitor is best can not dissolve in water. Should grease has excellent adhesion, used in FAG bearings grease must have antirust effect. And a layer of oil film can be formed in the steel surface. Cause leakage. During normal operation, oil will become soft in machining. Grease can by bearing to FAG bearings. If the mechanical stability of the oil is insufficient, operation process, can make the structure of the soap grease mechanical disruption of oil was damage, and loss of lubrication. FAG bearing operation process, the oil seal is necessary maintenance cylindrical roller bearing and lubricant from the barrier of external contamination. Regardless of debris or moisture can penetrate bearings, in case of causing damage to it. The correct device goes is one of the important factors play FAG bearing the longest service life. At the same time, must pay attention to the purity of the bearing, bearing of correctness and choose the proper installation and maintenance tools. In addition, the bearings must prevent contamination by pollutants and moisture, and ensure the right device and lubrication. Therefore, FAG bearings with column design, the status of the oil seal, type of lubricants and lubrication cycle, and special care are the same and important role. 1, low noise bearing installation and adjustment also can follow the long lifetime of cylindrical roller bearing grouping method makes the interference fit the size more consistent bearing clearance is relatively consistent and hope to cooperate with interference within may take smaller values to ensure the deformation of bearing raceway small and rolling body caused by noise. 2, clearance very ideal state is on the relationship between the noise when the highest temperature of bearing is in motion state clearance value is zero. Methods of judging clearance is too large, stationary state the extent of the shaft axial displacement of the reciprocating larger in big and heavy turbidity of a noise during operation. 3, if you send hate sharp whistlers when running shows too much bearing cylindrical roller bearing preload are preloaded should urge slants big prestressing degree of relaxation. If the clearance is too large to be able to make two bearing ring along the axial relative deviation: slightly reduced clearance and increase the axial rigidity of bearing noise reduced. 4, rolling element into the no-load zone will be sliding or being around move so can increase both noise can also cause wear and small clearance and big axial stiffness can eliminate the phenomenon. But clearance cannot be too small so as not to cause high temperature and shorten the life. 5, sometimes because of host working temperature range or shaft and a hole the size of the discrete big can't get a setting on a proper clearance in this case of cylindrical roller bearing outer ring of the elastic constant pressure preload method.
