In the market, found that operating a variety of brands of southern bearing shops such as cattle hair, but they sell the quality of the bearing, is it true that the packaging is labeled as the factory brand?This question probably in the heart of every car owner has been around a lot.Here are some common ways to identify the quality of a bearing:
Whether the stenciled words are clear or not: brand words and labels will be printed on the FAG bearing body.The font is very small, but most of the factory production using the stencil technology, and before the heat treatment on the press, so although the font is small, but deep, very clear.The typeface of the counterfeit product is not only blurred, but also floats on the surface due to rough printing technology, some of which can be easily erased by hand.
Whether there is a noise: the left hand holds the inner sleeve of the bearing, the right hand pulls the coat to make it rotate, listen to whether there is a noise.Because the production conditions of most of the counterfeit products are backward, completely manual workshop operation, in the production process will inevitably be mixed with sand and other impurities, hidden in the bearing body, so in the rotation will give out a noise.This is the biggest difference between a factory brand and one that strictly adheres to production standards and operates on machines.
Whether the packaging is clear: in general, the factory brand has its own special designers to design the external packaging, and arrange the factory passing the production conditions to make production, so the packaging from line to color is very clear, without ambiguity.(some imported brands also have special designs on the packaging to protect their intellectual property rights, which will be introduced in detail in the future).
Whether the surface has muddy oil stains: this should be paid special attention to when buying imported bearings.Due to the current domestic antirust technology is not particularly home, so the antirust processing was carried out on the bearing body and is easy to leave the thick oil stains, holding the thick thick, and imported from abroad can hardly see the trace of anti-rust oil bearing, is particularly careful expert said imported bearing smell a smell, must be under the anti-rust oil, just can't see.
Whether chamfering is even: the so-called bearing chamfering, that is, the intersection of horizontal and vertical surfaces, the counterfeit bearing due to the limitations of production technology, in these corner parts of the processing is not satisfactory.
