Teach you how to identify the quality of the bearing

Teach you how to identify the quality of the bearing 1, the outer packing is clear in general, normal manufacturer production of brand has its own professional design external packaging design, and arrange production with the conditions of the factory production, therefore, the packing of the product no matter from lines and colors should be clear, unambiguous. 2, seal character is clear every bearing products in body bearing products printed with the brand, label, etc. Although the font is very small, but normal manufacturer production printing products are adopted the steel seal technology, and before without overheating treatment of words, so the font although small, but deep concave, very clear. And usually, counterfeit products of font instead of fuzzy, because of printing technology coarse, font float to the surface, some even can easily erase traces or manually by hand. 3, if there is a complex ring bearing body with his left hand, right hand toggle coat to make it spin, listen to bearing ring if there is a noise in the process of operation. Because most of the counterfeit product production conditions, operation, fully manual mill bearing the body in the process of production inevitably mixed into impurities, dust, sand and so on bearing rotation will be mixed ring or not smooth phenomenon. This is to determine whether a product from the production standard strictly, and use the brand of machine operation of formal manufacturers product key. 4, if there is a muddy surface oil stains on the surface of whether there is a cloudy oil stains which need we should pay special attention to when buying imported bearings. Due to the current domestic antirust technology, there is still a gap with foreign advanced manufacturing countries, so the antirust processing was carried out on the bearing body is easy to leave a thick oil stains, contact with the hand feeling sticky thick, and imported from abroad on the bearing of almost can't see any sign of the anti-rust oil. According to the personage inside course of study introduces, particularly careful people can smell a special kind of imported bearing, this is the flavor of the anti-rust oil. 5, chamfering whether even so-called bearing chamfer, namely horizontal plane and vertical plane junction, fake bearing products because of the limitation of production technology in the area of the fringes processing unsatisfactory, as we can easily identify.
