Quality supervision experts remind consumers to buy qualified bearings, first of all to observe whether the outer packaging is clear, most of the genuine use of the stamping technology, and before the heat treatment, the font is pressed, so the font is small, but the recess is deep, very clear . The fonts of counterfeit products are vague, floating on the surface, and some can even be erased by hand. Secondly, if there is any turbid oil on the surface, if the anti-rust technology is not at home, it is easy to leave a thick oil stain, which is very sticky in the hand. At the same time, we must also pay attention to the choice of products with uniform chamfering and no noise.
