To distinguish the quality of the waste shredder machine bearing, we usually do the following:
1,waste shredder machine bearing outer packaging is clear
Under normal circumstances, the brands produced by regular manufacturers have their own special designers to design the external packaging, and arrange the production facilities to produce and produce. Therefore, the packaging of the products should be very clear from line to color. unambiguous.
2, waste shredder machine bearing steel printing is clear
Each bearing product will be printed with its brand name and label on the bearing product body. Although the font size is very small, the products produced by the regular manufacturers are printed by the stamp printing technology, and the characters are pressed before the heat treatment, so the font is small, but the recess is deep and very clear. Under normal circumstances, the fonts of counterfeit products are not only blurred, because the printing technology is rough, the fonts float on the surface, and some can even be easily erased by hand or serious by hand.
3, waste shredder machine bearing is noisy
Hold the inner sleeve of the bearing with your left hand, and rotate the outer sleeve with a small amount of the right hand to make it rotate, and listen to the noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products, it is completely hand-worked. In the production process, the bearing body will inevitably be mixed with impurities such as dust and sand. Therefore, when the bearing rotates, there will be noise or unsmooth operation. . This is the key to judging whether the product comes from a brand-name product of a regular manufacturer that is strict in production standards and operated by machines.
