轴承性能中只有25%取决于轴承的质量。其它因素,如安装,润滑和维护实际上对轴承寿命的影响最大。
Only 25% of bearing performance depends on the quality of the bearing . Other factors , such as installation, lubrication and maintenance is actually the greatest impact on bearing life .
 
装配不当
各种轴承提前失效的16%是由于装配不当(通常是由于用力过大…)和不会正确使用装配工具造成的。有些设备要求采用机械,液压或加热方法来进行正确而有效的安装和拆卸。轴承性能中只有25%取决于轴承的质量。其它因素,如安装,润滑和维护实际上对轴承寿命的影响最大。

装配不当
各种轴承提前失效的16%是由于装配不当(通常是由于用力过大…)和不会正确使用装配工具造成的。有些设备要求采用机械,液压或加热方法来进行正确而有效的安装和拆卸。轴承提供了基于各种专业工程服务技术的全套工具和设备,使得这些工作变得简单,快捷和更具成本核算效益。使用专用工具和技术进行专业的装配,是实现最大限度的延长机器运行时间的另一种解决方法。
Improper assembly
All kinds of bearing failure in advance , 16 % were due to improper assembly ( usually due to excessive force ... ) and not caused by the proper use of assembly tools . Some devices require the use of mechanical , hydraulic or heating method for proper and efficient installation and removal. Bearings offers a variety of professional engineering services technology based set of tools and devices , making these work easier , faster and more cost accounting benefits. Using special tools and techniques for professional assembly, is to achieve the maximum extension of the machine running time another solution .

润滑不当
尽管可以安装各种“免维护”密封轴承,但提前失效轴承中仍有36%是由于润滑脂的技术应用不正确和使用不当造成的。任何润滑不当的轴承都不可避免地在正常使用寿命之前提前失效。由于轴承通常是机械设备中最不容易装卸的部件,不经常润滑就会出现问题。在无法实现人工维护的情况下,轴承 可以制定全自动润滑系统来达到最佳润滑效果。只要根据要求采用了轴承 润滑脂,工具和技术进行有效的润滑,将有助于大幅度减少停机时间。
Improper lubrication
Although you can install a variety of " maintenance free " sealed bearings , bearings fail prematurely but there are still 36% is due to the incorrect application of grease technology and improper use . Any improper lubrication of the bearings will inevitably fail in advance of normal life . Since the bearing is usually the most difficult mechanical handling equipment components , lubrication problem occurs infrequently . In the case of manual maintenance can not be achieved , the bearing lubrication system can be developed to achieve optimal automatic lubrication. As long as the bearing grease according to require the use of tools and techniques for effective lubrication, will help to significantly reduce downtime.

污染
轴承是精密零件,如果轴承及润滑脂受到污染,将无法有效运行。此外,由于已经注有润滑脂的免维护密封轴承只占所有使用轴承中的一小部分,所以所有提前失效的轴承中至少有14%是由于污染问题造成的。SKF 拥有卓越的轴承制造和设计能力,可以为各种恶劣的工作环境提供密封解决方案。
Pollution
Bearings are precision parts, if the bearings and grease contamination will not operate effectively . In addition , as has been marked with grease maintenance-free sealed bearings all use only a small portion of the bearing , so all the early failure of the bearing at least 14% is due to problems caused by pollution . SKF has excellent bearing manufacturing and design capabilities , can provide a variety of harsh environments sealing solutions .

疲劳
如果机器出现过载、使用或维护不当,轴承都会受到影响,导致提前失效的轴承中有34%是由于疲劳引起的。由于轴承在维护不当或应力过大时会发出“提前警告”,可以用SKF轴承状态监控设备进行检测和分析,因此突然的或计划外的失效是可以避免的。
Fatigue
If the machine becomes overloaded , use or improper maintenance , the bearings will be affected , leading to premature failure of the bearing , 34 % were due to fatigue caused by . Since the bearing in the maintenance of inappropriate or excessive stress would be given "early warning " , you can use SKF Bearing condition monitoring equipment for testing and analysis, so sudden or unplanned failure can be avoided.

SKF轴承使用寿命分析的主要任务,就是根据大量的背景材料、分析数据和失效形式,找出造成轴承失效的主要因素,以便有针对性地提出改进措施,延长轴承的服役期,避免轴承发生突发性的早期失效。
SKF bearings life analysis of the main task is based on a lot of background material, analysis of data and failure modes, find the cause of bearing failure of the main factors in order to have targeted improvements to extend bearing service period, to avoid the occurrence of sudden bearing onset of early failure.
