Theoretically centrifugal pumps of FAG bearings used in life is 20,000-80,000 hours, but real life depends on many factors--premature bearing failure can lead to high cost of equipment downtime, and sometimes even lead to more serious consequences.
　　Satisfactory bearings FAG bearing service life started in the correct choice. From the outset, bearing Designer by selecting the correct bearings for different applications to prolong the life of FAG bearings and equipment performance. This process should take into account a number of factors, such as load, hardness, bearing life prediction, operating environment, and so on.
　　Correct storage
　　In principle, all FAG bearings prior to installation should be stored in their original packaging. They need to stay in a clean, dry and free of moisture, in the relatively constant temperature of the environment. FAG bearings should be kept away from water and dust, corrosive chemical substances. Shakes and vibrations may forever damage mechanical properties of bearing, therefore must be to avoid vibrations during handling and storage.
　　Basically, all bearing level must be saved, because after some heavier bearing vertical drop for a long time, may be deformation due to own weight.
　　Advance is coated with grease (or sealed) bearing requires special care, because after the oil after a long period of storage density changes. So when the bearings when used for the first time, there will be a certain degree of rotational noise. Therefore, such a FAG bearings hold time should be controlled according to the FIFO principle.
　　Clean
　　Clean the FAG bearing is very important. Bearing ring turning and rolling elements of surface roughness is usually one-tenth μ m, so smooth surfaces are very sensitive to damage caused by pollutants. Rotational surface lubrication layer is typically a 0.2~1 between μ m, size is greater than the lubricant particles of impurities will be excessive rolling bearings of rolling elements in steel by partial pressure, will eventually lead to permanent material fatigue. In addition to this, the external environment dust particles in the size up to 10 μ m, bearing damage may also occur. Therefore, clean, dust-free environment are critical for storage and installation of FAG bearings.
　　Thorough preparation and then install
　　FAG bearings appropriate tools should be used cautiously installation and removal. Industry experts estimate that FAG of premature bearing failure in the 16% is due to improper installation. For a large number of installations (such as in the production of devices), usually to strictly control installed, you can also use the appropriate bearings installed equipment.
