Common methods to identify the quality of imported bearings Whether the outer packaging is clear: In general, the Zhengchang brand has its own dedicated designers to design the outer packaging, and arranges factories that have passed the production conditions to produce and produce, so the packaging is from lines to color blocks. They are all very clear and unambiguous, and some imported brands also have unique designs on their accessories packages to protect their intellectual property rights. Whether the stencil is clear: brand words, labels, etc. will be printed on the bearing body. The font is very small, but most of the products produced by the factory use steel stamping technology, and the embossing is carried out before heat treatment. Therefore, although the font is small, it is deeply concave and very clear. The fonts of 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 any noise: Hold the bearing body sleeve with the left hand, turn the outer sleeve with the right hand to rotate it, and listen to whether there is any noise. Due to the backward production conditions of most of the counterfeit products and the completely manual workshop operation, it is inevitable that impurities such as sand will be mixed in during the production process and hidden in the bearing body, so there will be noises when rotating. This is the biggest difference between a genuine brand that strictly enforces production standards and operates with machines. Whether there are turbid oil marks on the surface: This should be paid special attention to when purchasing imported bearings. Since the current anti-rust technology in China is not particularly good, it is easy to leave thick oil traces when the bearing body is anti-rust, which is sticky and sticky in the hand, and the bearings imported from abroad are almost invisible. As for the traces of anti-rust oil, a very careful expert said that the imported bearings smelled a kind of smell, which must be anti-rust oil, but it was not visible. Whether the chamfer is uniform: the so-called chamfer of the bearing, that is, the junction of the horizontal and vertical surfaces, the counterfeit bearings are not handled well in these corners due to the limitation of production technology.
