The counterfeit bearings are not handled satisfactorily

Whether there is noise: Hold the inner sleeve of the bearing with your left hand, and tu the sleeve with your right hand to listen to whether there is any noise. The fonts are very small, but most of the products produced by the factory use steel stamping technology, and they are pressed before heat treatment. If you really can’t distinguish the sound, use a sound meter to check the size and sound quality of the rolling sound of the running imported bearing. Packaging Look at whether the outer packaging is clear: Under normal circumstances, the brand has its own dedicated designers to design the outer packaging, and arrange for production in factories that pass the production conditions, so the packaging is very clear from the lines to the color blocks.

Due to the backward production conditions of most counterfeit products and the completely hand-made workshop operation, it is inevitable that impurities such as sand will be mixed in the bearing body during the production process, so noise will be generated when rotating. Even if the bearing is slightly damaged such as peeling, it will emit abnormal and irregular sounds. will be printed on the bearing body. Therefore, although the fonts are small, they are deeply concave and very clear. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand. Able to distinguish.

Anti-rust oil Whether there are turbid oil stains on the surface: This should be paid special attention to when purchasing imported bearings. Steel seal Wheel Bearings suppliers Whether the stamping is clear: Brand words, labels, etc. Since the current domestic anti-rust technology is not very popular, it is easy to leave thick oil stains when anti-rust treatment on the bearing body, which is sticky and sticky in the hand, while it is almost invisible on the original imported bearings from abroad. vague. Due to the limitation of production technology, the counterfeit bearings are not handled satisfactorily at these coers. Based on years of experience, I will tell you the five major steps related to how to distinguish between true and false imported bearings, including bearing packaging, steel seal, anti-rust oil, and Analyze five aspects of angle and noise.

Use a sound meter.When buying imported bearings, many people don’t know how to distinguish between true and false. This is the biggest difference from a genuine brand that strictly enforces production standards and operates with machines. Whether the chamfer is uniform: the so-called chamfer of the bearing is the junction of the horizontal and vertical planes. The fonts of counterfeit products are not only blurred.. When it comes to the traces of anti-rust oil, a very careful expert said that the imported bearings smelled a kind of smell, it must be the anti-rust oil, but they can't see it.
