The first thing to judge is whether the outer packaging of Timken bearings is clear: whether the The Quality indication of the packaging is clear. Generally, the brands of the main factory have their own special designers to design the outer packaging.
After careful observation, they The Quality should be able to identify it, and arrange factories with qualified production conditions for production. Therefore, the packaging is very clear from lines to color blocks, Unambiguous. Some manufacturers will have some special identifiers, so pay attention
Then listen to the Timken bearing for any noise. Hold the inner The Quality sleeve of Timken bearing, move the outer sleeve to rotate it, and listen for any noise. This is a big difference from the original brand that produces Timken bearings and operates with machines.
The production conditions of most counterfeit products are backward and completely manual workshop operation. It is inevitable that The Quality impurities such as sand will be mixed in the production process and hidden in the Timken bearing,
so it will make a noise when rotating. Next, check whether The Quality there is muddy oil on the surface. Pay special attention when purchasing Timken bearings.
so it is easy to leave thick oil The Quality traces when antirust The Timken bearing body, and there is almost no trace of antirust oil on the original imported Timken bearing. If you are an expert, you can smell the antirust oil by smelling the taste of Timken bearing,
but you can’t see it. After that, check whether the chamfer is uniform, that is, at the junction of horizontal and vertical surfaces. Due to the limitation of production technology and the lack of high-tech equipment, fake Timken bearings will be poorly handled at these corners. It is not difficult to see if they should be carefully observed.
Then check whether the steel seal is clear. The Timken bearing body will be printed with brand words, The Quality labels, etc. The font is very small, but most of the products produced by the original factory use steel printing technology, and they are pressed before overheating treatment.
Therefore, although the font is The Quality small, it is concave – deep and very clear. If it is a fake product, its font is very fuzzy, because the printing technology is rough, the font floats on the surface, and some can even be easily erased with a wet cloth or hand.
