To identify the quality of equipment bearings, we usually proceed from the following aspects:
1. Is the outer packaging clear
Under normal circumstances, the brands produced by regular manufacturers have their own dedicated designers to design external packaging, and arrange for production in factories that pass the production conditions. Therefore, the product packaging should be very clear from the lines to the color blocks. unambiguous.
2. Is the steel stamp clear
Each bearing product will have its brand name, label, etc. printed on the bearing product body. Although the fonts are very small, the products produced by regular manufacturers are printed with steel stamping technology, and they are pressed before heat treatment. Therefore, although the fonts are small, they are deeply recessed and very clear. Normally, the fonts of counterfeit products are not only blurred. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand or have serious manual traces.
3. Is there any noise
Hold the inner sleeve of the bearing with your left hand, and turn the sleeve with your right hand to make it rotate slightly, and listen for noise during the operation of the bearing. Since most of the counterfeit products are under backward production conditions and are completely hand-crafted, it is inevitable that the bearing body will be mixed with impurities such as dust and sand during the production process, so noise or unsmooth operation will occur when the bearing is rotating. . This is the key to judging whether the product comes from a regular manufacturer's brand product that has strict production standards and is operated by a machine.
