在现代技术发展中,滚动轴承的使用寿命均能超过其计算寿命,轴承只要选型得当,润滑正确和维护良好,一般都能比与其配套的机器和设备的零部件具有更长的寿命,因而过早损坏的现象也较少。 但有时由于某种外界因素的影响,轴承在使用过程中也有没有达到全部计算（额定）寿命而造成早期损坏。在这种情况下,就应根据其征象,查明原因,采取有效措施,防止以后再次发生。
In the development of modern technology, the service life of rolling bearings can exceed their calculated life expectancy, as long as the proper selection of bearings, lubrication and maintenance of good, generally than with their matching machinery and equipment components have a longer life expectancy Early damage is less. But sometimes due to some external factors, the bearing has not reached the full calculated (rated) life expectancy during the use of early damage. Under such circumstances, we should find out the reasons according to their signs and take effective measures to prevent them from happening again in the future.
