Each bearing housing products will be bearing the bearing body of the product printed on its brand words, labels and so on. Although the font is very small, but the regular manufacturers of products using the stamp technology printing, but also in the heat treatment before the word is not carried, so the font is small, but concave deep, very clear. And usually, counterfeit products, not only the font is blurred, because the printing technology is rough, the font floating on the surface, and some even easily can be erased by hand or hand marks serious.
Whether there is noise
Left hand holding the bearing housing body sleeve, the right hand a small amount of back and forth toggle jacket to rotate, listen to bearing the process of running whether there is noise. As most of the production of counterfeit products behind the conditions, completely hand-workshop operation, in the production process will inevitably be incorporated in the bearing housing dust, sand and other impurities, so when the bearing rotation will appear noise or noise is not smooth The phenomenon. This is the key to judging whether a product comes from a branded product of a regular manufacturer with strict production standards and machine operation.
Whether the surface of turbid oil traces
The surface is turbid oil traces that we need to purchase imported bearings should pay special attention. As the domestic anti-rust technology and foreign advanced manufacturing countries there is a certain gap, so the bearing housing for rust treatment is easy to leave a thick traces of oil, feel thick sticky thick touch, and foreign The original imported bearing almost do not see any trace of anti-rust oil. According to industry insiders, particularly careful people can smell the imported bearing seat to a special taste, this is the taste of rust-proof oil.
