Automobile bearings generally use imported bearings, so the current imported automobile bearings are still very good, the quality is very good, the domestic automobile bearings are relatively cheap, the current imported bearings a lot of product quality is good, NSK imported bearings and FAG imported bearings, as well as SKF imported bearings are suitable for automobile bearings. Walking in the auto parts market, found operating a variety of brands of bearings as much as a cow's hair, but they sell the quality of bearings, whether it is really marked on the packaging is the brand? This question is probably in the heart of every owner has been around a lot of times. The following introduces several methods of identification of imported automobile bearings

Whether the steel seal is clear: the bearing body will be printed with brand words, labels, etc. The font is very small, but most of the products use steel printing technology, and it is pressed before being overheated, so although the font is small, it is deeply concave and very clear. The fonts of the counterfeit products are not only vague, but because of the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand.
Whether there is noise: the left hand holds the bearing body sleeve, the right hand flicks the jacket to make it rotate, listen to whether there is noise. Due to the backward production conditions of most counterfeit products, completely manual workshop operation, it is inevitable that impurities such as sand will be mixed in the production process, hidden in the bearing body, so it will emit noise when rotating. This is the biggest difference between brands that strictly implement production standards and operate with machines.
Whether there is a muddy oil stain on the surface: this should be paid special attention to when purchasing imported bearings. Because the current anti-rust technology is not particularly home, it is easy to leave a thick oil stain when the bearing body is treated with rust, which is sticky and thick in the hand, and the bearings imported from abroad can hardly see traces of anti-rust oil, but a particularly careful expert said that the imported bearings smell like a taste, it must be under the anti-rust oil, but can not see it.
Whether the chamfer is uniform: the so-called chamfer of the bearing, that is, the intersection of the transverse plane and the vertical plane, the counterfeit bearing is not handled satisfactorily in these corners and corners due to the limitations of production technology.
