除非采用正确的使用、保管、安装的方法以及随后的维护方法,否则轴承不能长期工作。这些因素都能缩短——有时是急剧地——预期的轴承使用寿命。轴承故障通常与润滑或装配不当及诱发因素有关。大多数主要轴承厂提供检查鉴定的技术帮助和有关轴承使用时损坏情况的报告。 各种故障类型的百分率依起因而不同,但一般是70％由于润滑与装配,20％由于诱发因素,10％由于轴承已达到疲劳极限或设计寿命。 Bearings can not be used for a long period of time unless properly used, stored, installed, and subsequently maintained. These factors can be shortened - sometimes dramatically - the expected bearing life. Bearing failures are often associated with lubrication or improper assembly and triggering factors. Most major bearing manufacturers provide technical assistance for inspection and identification and reports on the damage to the bearings when used. The percentage of each type of failure varies by cause, but is typically 70% due to lubrication and assembly, 20% due to triggering, and 10% due to bearing fatigue limit or design life.
