At present, the price of NSK imported bearings in China ranges from 100 yuan to 3000 yuan, while the counterfeit NSK imported bearing products are only about 20% of the genuine price.

Bearings produced by regular manufacturers need to pass a series of tests and quality inspections to ensure safety, while counterfeit products with low prices and without any tests usually use inferior bearing steel materials instead of high-quality steel, which will wear out in advance during use. Not only does the bearing not play its due role, but it will even bring serious damage to other equipment, resulting in damage to the whole machine and danger.

The method of distinguishing authenticity is as follows:

Take a look at the packaging of NSK imported bearings: the counterfeit "NSK" brand bearing packaging is slightly different from the genuine "NSK" brand bearing packaging. The "NSK" trademark marked on the right side of the box is bold in red, while the genuine "NSK" trademark is bold in white.

Bi Er NSK imported bearing shaft: Compared with the genuine product, the paint film surface of fake "NSK" brand bearing is slightly uneven. Fake and shoddy bearings have no anti-corrosion measures and no sealing and lubrication, and their sensory quality is obviously lower than that of genuine ones. In addition, by identifying the product certificate, bearing model identification and special anti-counterfeiting mark, the authenticity can also be identified.

Third, the weight of bearings imported by NSK: the materials used in counterfeit bearings are obviously less than the genuine ones. Because most fake bearings cut corners, replacing high oxidation special steel with ordinary steel will be lighter than genuine ones.
