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.
To distinguish the quality of equipment bearings, Yidong Bearing Professional is shared for you from the following aspects:
Whether the 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.
Whether the 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.
Is there a noise:
Hold the inner sleeve of the bearing with your left hand and turn the outer sleeve with your right hand to rotate it to hear if there is any 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.
Is there any turbid oil on the surface:
Whether there are turbid oil marks on the surface requires special attention when purchasing imported bearings. Since the current domestic anti-rust technology has a certain gap with the foreign advanced manufacturing countries, it is easy to leave a thick oil trace when the bearing body is rust-proofed, and it feels sticky and sticky when touched by hand. There is almost no trace of rust preventive oil on the imported bearings. According to industry insiders, particularly attentive people can smell a special taste on imported bearings, which is the taste of rust-proof oil.
Whether the chamfer is uniform:
The so-called chamfering of the bearing, that is, the intersection of the horizontal and vertical faces, the counterfeit bearing products are handled unsatisfactorily at the corners of these corners due to the limitation of production technology, which we can easily distinguish.
