理论上离心泵中滚动SKF轴承的使用寿命为20000~80000小时,但是,实际的寿命取决于许多因素——过早的SKF轴承失效会导致代价高额的设备停工,有时甚至还会导致更严重的后果。  
Scrolling in the theory of centrifugal pump SKF bearing life of 20,000-80,000 hours, but actual life depends on many factors--the premature SKF bearing failure can lead to high cost of equipment downtime, and sometimes it will even lead to more serious consequences.
令人满意的SKF轴承使用寿命始于正确的SKF轴承选择。从一开始,SKF轴承设计师通过为不同应用选择正确的SKF轴承来延长SKF轴承使用寿命和设备性能。这个过程要考虑许多因素,例如载荷、硬度、SKF轴承寿命预测、运行环境等等。   
Satisfactory SKF bearings SKF bearing life started in the correct choice. From the outset, SKF bearing Designer by selecting the correct SKF bearings for different applications to extend the life and performance of SKF bearings. The process to take into account a number of factors, such as load, hardness, SKF bearing life prediction, operating environment, and so on.
正确的储存   
原则上,所有SKF轴承在安装之前都应该保存在它们原来的包装中。它们需要留在清洁、无湿气、相对恒温的环境中。滚动SKF轴承应该远离灰尘、水和腐蚀性化学物质。摇动和震动可能会永远破坏SKF轴承的机械性能,因此在处理和储存过程中必须避免震动。   
Correct storage
In principle, all SKF bearings should be stored in their original packaging until installation. They need to stay in a clean, dry and free of moisture, in the relatively constant temperature of the environment. Scroll SKF bearings should be kept away from dust, water and corrosive chemicals. Shaking and vibrations may forever damage mechanical performance of SKF bearings, so the vibrations must be avoided during handling and storage.
基本上,所有SKF轴承都必须水平保存,因为有些较重的SKF轴承长时间竖直放置后,可能会由于自身的重量而变形。   
Basically, the levels of all SKF bearings must be saved, because some of the heavier SKF bearings after a long vertical drop, may be because of their weight and deformation.
预先涂有油脂的(或密封的)SKF轴承需要特别小心,因为油脂经过长时间的存储后密度会改变。这样当SKF轴承第一次使用时,会有一定程度的转动噪音。因此,这种SKF轴承的搁置时间应该按先进先出的原则来控制。  
Previously coated with grease (or seal) of SKF bearings require special care, because oil after a long period of storage density changes. So when the SKF bearings when used for the first time, there will be a degree of rotational noise. Therefore, this should set aside time for SKF bearings to control on a first in, first out basis.
清洁   
清洁对滚动SKF轴承非常重要。SKF轴承环转动面和滚动元件的表面粗糙度通常为1/10 μm,如此光滑的表面对污染物造成的损坏非常敏感。转动面之间的润滑层通常为0.2~1 μm,大于润滑剂粒径的颗粒型杂质会受到滚动元件的过度碾压而在SKF轴承钢中产生局部压力,最终会导致永久性材料疲劳。除了这一点,外界环境中的灰尘颗粒大小可达10 μm,也会对SKF轴承造成损坏。因此,清洁无尘的环境对SKF轴承的存储和安装来说至关重要。   
Clean
Clean rolling SKF bearings are very important. SKF bearing ring surface roughness in turning and rolling elements of typically one-tenth μ m, smooth surface is very sensitive to damage caused by pollutants. Turn the lubrication between the surface layer is typically a 0.2~1 μ m, size is greater than the lubricant particles of impurities will be subject to excessive rolling of rolling elements and partial pressures in the SKF bearing steel, will eventually lead to permanent fatigue. In addition to this, the external environment of dust particles in sizes up to 10 μ m, also on SKF bearing damage. Therefore, clean and dust-free environment for storage and installation of SKF bearings are critical.
