With the continuous increase in domestic car ownership, the demand for auto parts and automotive supplies has also been on the increase. However, the large and small parts and accessories stores in the market are numerous and complex. The goods in the market vary greatly and many counterfeit products are removed Among them, the owners of the loss, in serious cases, even lead to casualties. The following describes to the owners of various types of friends, the major brands of auto parts to identify the way. Hope that "respect the brand, eliminate fake, use genuine" concept can penetrate the hearts of the people. It's not a mistake to call a bearing a car's joint. In a car, not only its four legs - the wheels need to use bearings, but all parts of the machine will be turning the bearings involved, it is very inconspicuous in the transmission system is something of great importance. Because of heavy workload, its wear is relatively high, so the replacement of the bearing is more common in vehicle maintenance. Walking in the auto parts market, found that operating a variety of brands bearing shop superb, but how they sell the quality of the bearing, is really as marked on the packaging is the factory brand? This question probably around every car owner have wandered many times. The following describes several commonly used methods to distinguish the bearing quality: Outer packaging is not clear Under normal circumstances, the factory brand has its own dedicated designer to the packaging design, and arrangements for the production of the conditions of the factory to produce production, packaging, no matter from the lines To the color blocks are very clear, unambiguous. Steel lettering is clear in the bearing body will be printed on the brand words, labels and so on. The fonts are very small, but most of the products produced by the factory use stamping technology, and are pressed before being heat-treated. Therefore, the font size is small but deep and very clear. The fake fonts not only fonts, due to rough printing technology, fonts floating on the surface, and some even easily can be erased by hand. Whether there is noise affect the left hand holding the bearing sleeve, the right hand toggle the coat to make it rotate, listen to it if there is noise. Since most of the counterfeit products have poor production conditions and completely hand-operated workshops, it is inevitable that impurities such as sand will be mixed in the production process and hidden in the bearing body, so the noise will be spun during rotation. This is the biggest difference between a manufacturer's brand and a machine manufacturer that strictly enforces production standards. Whether the surface is turbid oil This should pay special attention to the purchase of imported bearings. As the current domestic anti-rust technology is not particularly home, so the bearing body rust treatment is easy to leave thick traces of oil, sticky in the hands of sticky, and imported bearings almost no look To the traces of rust-proof oil, it touches particularly careful expert said that there is a smell of imported bearings, it is certainly anti-rust oil, just can not see it. The chamfer is even The so-called bearing chamfer, that is, the intersection of the cross-section and the vertical, fake bearings due to production technology restrictions in these parts of the corner corner handling unsatisfactory.
