Distinguish between bearing true and false

, product packaging: the packaging of each bearing are specially designed and identity from the material of packaging, packaging color, style, logo, security, environmental protection, as well as to the product safety, convenient transportation and so will have a full range of design and consideration, and the different period of product packaging color, style, logo, security may be different. Such as / 29434 e bearing recent packaging is wooden packing, the environmental protection is the inner packaging moistureproof paper with polyester adhesive tape, etc. , may be some time after the anti-counterfeiting packaging change it again and the logo also changed and not particularly to inform you only know and understand the different and change, is possible to distinguish counterfeit and shoddy products. Second, the seal character is clear: the bearing body would be printed with brand, label, etc. Font is very small, but is produced by the factory are mostly use seal technology, and before disposal without overheating of words, so the font though small, but deep concave, very clear. And counterfeit products font instead of fuzzy, because of printing technology coarse, font float to the surface, in some cases can be easily erased by hand. Three, such a complex ring: the bearing body with his left hand, right hand toggle coat to make it spin, listen to its hybrid ring. Because most of the counterfeit product production conditions, operation, fully manual mill production process will inevitably mixed into the sand kind of impurity, hidden in the bearing body, so makes a noise when rotating ring. This is and strict production standard, and use the machine operation are factory is the biggest difference between brands. 4, if there is a cloudy appearance soil: this should pay special attention to when to buy imported bearings. Due to the current domestic antirust technology is not particularly home, so the antirust treatment was carried out on the bearing body and it is easy to leave the thick oil stains, holding the thick thick, and imported from abroad can hardly see the trace of anti-rust oil bearing, is particularly careful expert said imported bearing smell a smell, must be under the anti-rust oil, just can't see. Five, the chamfer whether uniform: so-called bearing chamfer, namely horizontal plane and vertical plane junction, counterfeit bearings due to the limitation of production technology, these fringes of disposal.
