Identify the five department of imported bearings of true and false

A lot of people when buying imported bearing, don't know how to discern between true and false, China bearing network, according to many years of experience tell us about how to distinguish true and false problems related to the imported bearing five steps, respectively from the packing of the bearing, seal, rust-proof oil, chamfering and noise five aspects were analyzed. 1, packaging, whether the outer packing is clear: in general, are factory brand has its own professional design external packaging design, and arrange production with the conditions of the factory production, so the packing is very clear, from the lines to the colors. 2, seal seal character is clear: on the bearing body printed with brand, label, etc. Font is very small, but is produced by the factory are mostly use seal technology, and before without overheating treatment of words, so the font although 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. 3 oil, rust-proof oil surface whether there is turbidity is: 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 processing was carried out on the bearing body and 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. 4, chamfering chamfer whether uniform: so-called bearing chamfer, namely horizontal plane and vertical plane junction, counterfeit bearings because of the limitation of production technology in the area of the fringes is handled. 5, if there is a noise of mixed ring: the bearing body with his left hand, right hand toggle coat to make it spin, listen to its hybrid ring. Due to the backward production conditions most of the counterfeit products, fully manual mill operation, in the process of production 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 standards, and use machine operation are factory is the biggest difference between brands. If is unable to distinguish between the sound with the sound of the measuring device for rolling sound of imported bearing in operation and quality inspection, the size of the bearing even with slight stripping damage, also an exception and irregular, and with the sound of the measuring device can distinguish. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
