求翻译：●用好滚动轴承的注意事项： 滚动轴承是一种精密的机械支承元件，轴承用户深切希望装在主机上的轴承能够在预定的使用期内不致损坏并保持其动态性能，但客观事实有时并非尽如人意，突发的轴承失效事故会给用户造成重大损失。通过大量的滚动轴承失效分析研究表明，轴承短寿或过早的丧失精度，有的是由于材料缺陷或制造不当所致，但在相当大的程度上是由于没有严格按照轴承使用要求进行安装、维护，或者是轴承选型不当或实际载荷超过轴承本身的额定载荷等原因造成轴承的非正常损坏，例如，轴承零件的疲劳剥落在很大程度上就是因为润滑油中混有杂质引起的。可见，要想实现滚动轴承具有更长的寿命和精度保持期，除要求轴承制造厂家提高产品质量外，轴承用户也必须用科学的方法和程序使用轴承，否则，再好的轴承也会在恶劣的随意的使用条件下夭折。是什么意思？

Considerations for using rolling bearings: roller bearing is a precision of mechanical support components, users hope for bearings mounted on the host in the intended use will not be damaged and to maintain its dynamic performance for the period, but the objective fact sometimes was not satisfactory, sudden bearing failure accident caused major losses to the user. Through large of rolling bearing failure analysis research indicates that, bearing duanshou or prematurely of lost precision, some because material defects or manufacturing improper caused by, but in quite large of degree Shang is because no strictly in accordance with the bearing using requirements for installation, and maintenance, or is bearing selection improper or actual load over bearing itself of rated load, causes caused bearing of non-normal damaged, for example, bearing parts of fatigue spalling in is large degree Shang is because lubricant in the mixed has impurities caused of. Visible, to achieve accuracy of rolling bearings have longer life expectancy and the retention period, apart from bearing manufacturers improve product quality, users must also use bearing with scientific methods and procedures, otherwise, no matter how good the bearings will die under the harsh conditions of use of the arbitrary.
