How many years is the bearing life?

Imported bearings can be used for 2-5 years, while domestic bearings are generally more than 2-4 years. At present, the main shaft bearings are mostly unnatural damage, and most of them are premature damage caused by bearing the intrusion of foreign objects. It is impossible to say that the service life of imported bearings is better than that of domestic bearings. You should first know how bad your bearing is, and then decide whether to use domestic or imported bearings. Imported bearings have higher long-term service life, good operation accuracy and good machining finish. It mainly depends on the service condition. The service life is closely related to the service environment.
