How to choose the right bearing for your application?

NSCB has always been committed to providing customers with the highest quality service and is proud to produce excellent products and provide accurate technical services. The bearings we sell as agents are designed and manufactured with the highest level of precision, and all have the highest quality standards, however, no bearing is forever, so how can you ensure that a bearing will perform well throughout its service life?

 

It is known that rolling bearings are very reliable, and many bearings even last longer than the machines on which they are installed. However, several factors can shorten the service life of rolling bearings, and overloading and overspeeding are the most important causes of early failure of bearings. Loads that exceed the bearing specifications will Accelerated fatigue shortens its life by 8 to 10 times, and rotational speeds that exceed specifications can also significantly reduce bearing life. There are also other factors, such as extreme temperatures, vibration, dust or contaminants, which play an important role in bearing life. effect.

 

If the bearing is selected correctly and used in the right application, the bearing will definitely last to its rated life (and possibly longer). Approximate values of bearing life in operating hours are listed below. You can expect different application.
