2, other aspects compared with domestic bearings; imported bearings usually have better raw materials than domestic; heat treatment process is better than domestic; high precision; production and installation process is more reasonable; but the use of long life; of course; the price is higher. And imported bearings are usually more authentic; the most important thing is. . . . . . Imported bearings are made in foreign countries. Haha; this is not to be understood by us.
