NSK bearings

It’s not obvious; with this little information, we have to wait for the experts. We’re using FAG for now

1: When opening the box, one can see that the NSK bearings have a very attractive appearance. Japanese bearings generally pay great attention to their appearance; one key feature is that they have larger chamfers, and the chamfers on NSK bearings are usually colored brightly. When gently pushing the grooves of an NSK bearing with your hand, it feels very smooth with no signs of blockage; the feel is excellent. It’s quite difficult for counterfeit bearings to replicate these subtle details, especially the grooves, to such a degree that they can compare to those of NSK bearings. 2: Check the packaging: The outer packaging of counterfeit \"NSK\" brand bearings differs slightly from that of genuine \"NSK\" brand bearings; the \"NSK\" trademark printed on the right side of the packaging box is in red bold letters, whereas the genuine \"NSK\" trademark is in white bold letters. In terms of their appearance, NSK bearings are usually packaged in paper boxes; the color of these boxes is dark blue, and the bearing model printed on them is clearly visible, thanks to NSK’s anti-counterfeiting technology. It’s difficult for fake bearings to achieve this; the color of the box is relatively light and it fades easily. The font used for indicating the bearing model is also rather blurry. NSK bearings are usually packaged in cardboard boxes that are dark blue in color; the NSK bearing model printed on these boxes is clear, and NSK’s anti-counterfeiting technology is employed. It is difficult for fake NSK bearings to achieve this; their casing is lighter in color and tends to fade easily, and the printing on the NSK bearing models is also rather blurry. 3: Weight measurement: For bearings of the same model, counterfeit \"NSK\" bearings use significantly less material than genuine ones. Since most counterfeit bearings use inferior materials by replacing high-oxidation specialty steel with ordinary steel, they are lighter in weight than genuine ones. 4: Is there any noise? Hold the inner sleeve of the bearing with the left hand, and use the right hand to rotate the outer sleeve to listen for any noise. Due to the poor production conditions of most counterfeit products, impurities inevitably get mixed in during the manufacturing process and remain inside the bearing, which causes abnormal noises when it rotates. This is the biggest difference between them and genuine brand products that strictly adhere to production standards and are operated by machines. 5: Uniformity of the chamfers: The chamfers on bearings refer to the junctions between the horizontal and vertical surfaces. Due to limitations in manufacturing technology, counterfeit bearings fail to provide satisfactory treatment at these edges and corners. 6: Of course, the price of NSK bearings is much higher than that of domestic bearings; trying to buy NSK bearings at the price of domestic ones will result in getting fake products. 7: Appearance of NSK bearings: NSK bearings generally have a very attractive appearance, as the Japanese company NSK pays great attention to their design. One key feature is that the chamfers on NSK bearings are relatively large, and these chamfers are usually colored in bright shades. When gently pushing the channels of an NSK bearing with your hand, it feels very lubricated with no signs of blockage; the feel is excellent. It’s difficult for counterfeit NSK bearings to replicate these subtle details, especially the channels, which cannot compare to those of genuine NSK bearings. 8: Scan using the NSK Verify APP on your smartphone.

There are still many fake NSK bearings

There are still many fake NSK bearings

It’s hard to tell; in fact, the quality of domestic products these days isn’t that bad.
