To identify whether NSK bearings are imported genuine products, the first problem is that you need to master imported genuine NSK bearings. You need to master, understand and understand imported genuine bearings, know its appearance, and know its structure. Only by fully grasping the imported genuine NSK bearings can you expose the fake products in front of your eyes and point out where they are fake, so as to avoid unnecessary problems and losses. How to distinguish the true and false of NSK bearings? Generally, it is divided into the following points: 1. Whether the outer packaging and the outer packaging box are clear. Under normal circumstances, well-known imported brands have professional design staff to complete the design concept of the outer packaging box, and at the same time arrange the necessary production and manufacturing. Qualified processing factories complete the production and manufacturing, so the packaging boxes are very clear and unambiguous from the texture to the color block pictures. Some imported well-known brand spare parts packaging boxes are professionally used to protect their own national intellectual property rights. unique design concept. 2. Is the stamped word clear? Each bearing product has its own brand fonts, labels, etc. printed on the surface of the bearing product. Although the font size is very small, the products produced by regular manufacturers are printed with steel stamping technology, and the characters are embossed before heat treatment. Therefore, although the font size is small, it is deeply concave and very clear. The fonts of counterfeit products are not only blurred, but due to the rough printing technology, the fonts float on the surface, and many of them can even be easily erased by hand. 3. Is there any noise? Hold the inner sleeve of the bearing with your left hand, turn the outer ring with your right hand to make it rotate, and listen to whether there is any noise. Due to the relatively backward production conditions of most counterfeit products, and the complete manual workshop operation process, it is inevitable to mix tiny particles of impurities in the production process, which are hidden in the bearings, so there will be noise when rotating. This is the biggest difference from well-known brands that strictly implement production standards and operate processes with machinery and equipment. 4. Whether there are turbid oil stains on the surface should be paid great attention to when purchasing imported bearings. Since the anti-rust technology in China is not very advanced at the present stage, it is easy to leave thick oil stains when the bearing body is anti-rust, which is sticky and sticky in the hand, but it is basically invisible on the bearings imported from abroad. The traces of anti-rust liquid, but a very careful insider said that the imported bearings smell a kind of smell, it is indeed the anti-rust liquid, but it is invisible. 5. Is the chamfer uniform? The so-called chamfer of the bearing is the junction of the horizontal and vertical surfaces. Due to the limitation of manufacturing technology, the counterfeit bearings are perfectly processed at these corners and corners. 6. The weight of counterfeit bearings is obviously smaller than that of genuine bearings. Since most counterfeit bearings are shoddy, replacing high-oxidized special steel with ordinary steel will be lighter than the original bearings in terms of weight. 7. Comparing prices The price of imported bearings is naturally much higher than that of domestic bearings. If you buy imported bearings at the price of domestic bearings, you will get fake ones. The last point, since imported bearing products are selected, while being careful and cautious, you should also avoid greedy for cheap, so as not to suffer a big loss. The production and manufacture of all products must have a certain cost, and these costs are precisely determined by the actual factors of the product price. As the saying goes, 'you get what you pay for', and the same is true for bearing products.
