Practice the eye of the fire eye; easily distinguish between true and false bearings for the product of impersonation bearing; the market usually saves the production cost from the raw materials, packaging, brand, shoddy, fake and real methods; in order to achieve high profitability.
The main bearing frauds in the current dealers of the bearing market are:
1. Bearings made of iron and carbon steel and modified scrap bearings are used to reject bearing products; such products often have large errors in hardness and precision.
2. The bearing products of the defective price and the bearing products of the local small factories are marked with the registered trademarks of the big brand manufacturers; such products are usually used in the brand image to achieve the purpose of fraudulent consumers.
3. Pretending to be a well-known manufacturer, distributor, agent; and even pretending to be the spot market department of the manufacturer.
4. Manufacturing steel. Dull-flat tons of 蜃 straight 涑 D-class bearings,
5. In the genuine bearing products, fake goods are sold,
6. Defrauding the consumer at the price of the product; shoddy according to the consumer’s practice of the bearing product; replacing the real thing with a fake
7. Appearance firstly distinguishes the bearing color from the bearing shaft color. It can fully reflect the raw material status of the bearing product; for most of the impeller bearing products; usually in the steel selection context. It is well known that the price of steel is also an important reason for the resolution of the price of bearing products; therefore, some cities have made a big fuss about the use of steel; the type of steel is reduced; the shoddy is used. The general steel, carbon steel, Ma Steel and other raw materials are used; Some even use iron pipes instead of steel products. Therefore, the color of the bearings is very different from the genuine products; these price data are mostly white in appearance; the green color of the bearing steel is more obvious. The difference.
8. The outer packaging of the bearing products is also the same as the normal consumption of the bearing; the outer packaging of the bearing product is also directly related to the quality of the product. Because of the brand image and the influence of the shopping mall; the bearing manufacturer of the big brand is in the product The depiction of the appearance of the installation will also be a great effort; not only in the trademark, packaging color and depiction of the characteristics of the embodiment; whether the line is still very clear and bright on the module. And small manufacturers in order to save costs; on the product packaging Will cut corners; the appearance is ambiguous.
9. Stamping is an important factor in distinguishing the authenticity of bearings. For most bearing products, the bearing body of the bearing will be printed with parameters such as brand, typeface and label. Regardless of the font size of the stamp, it will use professional stamps. Skill; this type of stamp is before the bearing has passed through the heat treatment; it is pressed; thus the font is clear.
10. The oil trace of the bearing body is also not negligible. The oil trace of the external surface of the bearing directly determines the rust prevention ability of the bearing product; especially for the bearing products of the world's major manufacturers; although the bearing embodiment has passed the rust prevention treatment; The appearance of the bearing is still as bright as new; no oil is found. For some impersonated bearing products; in order to reach the rust-proof destination, thick oil will be added to the bearing; this will lower the bearing body itself. brightness.
The above points are several simple ways to distinguish bearing products from the appearance of the bearing; although only some skins are said; but through careful discussion; still find significant differences between true and false bearings.
