Identify the quality of equipment bearings, Hunan Jintai Hardware and Machinery Co., ltd. From the following aspects:
1, whether the packaging is clear
Under normal circumstances, the regular manufacturers of the brand has its own design and design of external packaging design, and arrange the production conditions of the factory to produce production, therefore, the product packaging from the line to the color block should be very clear, unambiguous.
2, steel printing is clear
Each bearing products will be printed on the body of the bearing body with its brand name, label and so on. Although the font is very small, but the regular manufacturers of products used in the printing technology printing, and not before the heat treatment before the word, so the font is small, but concave deep, very clear. And usually, counterfeit products, the font is not only blurred, because the printing technology is rough, the font floating on the surface, and some even easily can be wiped by hand or hand traces of serious.
3, whether there is a noise
Left hand holding the bearing body sets, right hand toss the jacket to rotate, listen to the bearing during the operation of whether there is a noise. As most of the counterfeit products production conditions behind, completely hand-workshop operation, in the production process will inevitably be incorporated into the body of dust, sand, a class of impurities, so when the rotation of the bearing will appear when the noise or running is not smooth The This is to determine whether the product from the strict production standards, and the use of machine operation of the regular manufacturers of the key brand products.
4, whether the surface of turbid oil traces
Whether there is a turbid oil on the surface This requires us to buy bearings should pay special attention. As the current domestic anti-rust technology and foreign advanced manufacturing countries there is a certain gap, so the rust-proof body when the bearing body is easy to leave a thick oil traces, hand contact feel thick sticky, and foreign Original imported bearings almost do not see any trace of anti-rust oil. According to industry insiders, particularly careful people can smell a special taste in the imported bearings, which is the taste of anti-rust oil.
5, chamfer is uniform
The so-called bearing chamfer, that is, the intersection of the horizontal and vertical, counterfeit bearing products due to the limitations of production technology, in these corner of the corner of the disposal of unsatisfactory, which we can easily identify.
