How to identify counterfeit imported bearings "Eight Blacks" It is not difficult to identify genuine and counterfeit bearings. According to the inspection of bearings in the market, there are eight kinds of fraudulent means in bearing distribution at present: manufacturing bearings with iron and carbon steel (insufficient hardness) and repairing waste bearings (insufficient accuracy); Brand inferior bearings and small factory bearings with the trademark of big factory, and fake the internal and external packaging and certificate of conformity of famous big factory products; Fake the users, dealers and agents of famous manufacturers, or even fake the spot sales department of manufacturers; Fake defective bearings as genuine bearings; Typing ordinary grade bearings into D grade bearings; Good goods are mixed with fakes; Fake goods sell at genuine prices, genuine goods sell at D-level prices, and use fake price books; If you want a bargain, give it to a fake, and if you want a good quality, give it to the real thing. Quality supervision experts remind consumers that to buy qualified bearings, we must first observe whether the outer packaging is clear. Most genuine products use steel seal technology, and they are pressed before overheating. Therefore, although the font is small, it is deeply concave and very clear. The fonts of counterfeit products are blurred and floating on the surface, and some of them can even be erased by hand. Secondly, look at whether there are muddy oil stains on the surface. If the anti-rust technology is not at home, it is easy to leave a thick oil stain, which is very sticky in your hand. At the same time, we should also pay attention to the selection of products with uniform chamfering and no noise in rotation. How to buy reliable bearing products 1. Buy directly from the manufacturer. Bearings and related products produced in China can be purchased directly from production enterprises; Foreign brands can contact the brand's institutions in China. 2. Buy from reputable agents and sales companies of enterprises. Large domestic enterprises generally have their own sales branches all over the country, and generally the branches of these enterprises will not sell fake goods; Well-known foreign brands generally have their own designated agents in China. Pay attention to whether the merchant has the agency certificate when purchasing. 3, don't covet cheap, buy cheap bearings in the hands of some merchants without qualification certification. Bearing production has cost, and bearing price is determined by cost. The products of well-known enterprises have strict control over raw materials, production processes, etc. in the production process, which will increase the cost on the basis of ensuring the quality of their products, so the market price will not be very low!

In order to reduce the manufacturing cost, there is no requirement for accuracy. In order to reduce the price, poor quality bearing steel materials are used. The packaging and transportation treatment methods are not standardized, which has a negative impact on the accuracy of bearing products. There is also a general lack of advertising for regular agents, while counterfeit companies are just the opposite.
