Bearing grease selection will directly affect the stable operation of the equipment, in order to better play the best conditions of FAG bearings, the following are several important factors in selecting grease: mechanical type; bearing type and size; working temperature; workload; speed; working conditions, such as vibration and spindle orientation is horizontal or vertical; cooling; sealing effect; the external environment.
The use of FAG bearing grease must have antirust effect, anti-rust agent preferably insoluble in water. Grease has good adhesion, and can form a layer of oil film on steel surface.
The oil will become soft in the mechanical machining, resulting in leakage. During normal operation, oil will be knocking bearing self-aligning ball bearing. If the grease is not enough mechanical stability, operation process, will make the oil soap structure produces mechanical disintegration, resulting in destruction of fat, resulting in loss of lubrication.
Because of its convenience lubrication cost and use, 80% bearing adopts the sliding bearing lubrication, FAG put grease as bearing the " basic elements ", and the bearing, the bearing seat and the sealing is equally important. Rolling bearing based on the abundant experience of research and development, through test and study continuously, bearing grease production quality, to meet the on-site application of the corresponding. Self-aligning ball Engineering Research Center developed a strict standard and test parameters for bearing grease, and has become the bearing grease reference internationally recognized.
It is a wealth of knowledge and experience of FAG in application and research based on bearing lubrication, to provide services in a self-aligning ball bearing lubrication is the core of the full lubrication for customers, lubrication problems, to solve the industrial enterprises long-term problems such as improper selection: lubricants, lubrication is insufficient mechanical failure, determine the cycle and lubrication the amount of lubrication, lubricant consumption of too much, the lubrication of the environmental pollution and so on. In order to help enterprises to improve the quality and efficiency of lubricant, ensure that the equipment operation rate and reduce the cost.
If the wrong choice grease all FAG bearing prevention measures in vain, choose a kind of grease, it is the base oil viscosity at operating temperature is able to provide sufficient lubrication effect is very important, viscosity is mainly affected by temperature, which along with the temperature rise and fall, when the temperature drop is that it increased. Therefore, must know the base oil viscosity at operating temperature. Machine manufacturers often specify the use of a grease, but for most of the standard grease a wide scope.
