To distinguish the quality of equipment bearings, we usually carry out from the following aspects:
Whether the outer packaging is clear.
In general, brands produced by regular manufacturers have their own dedicated designers to design the outer packaging, and arrange the production conditions for factories to produce Therefore, the packaging of the product should be very clear and unambiguous from the line to the color block.
Is the steel printing clear?
Every bearing product will have its brand name, label, etc. printed on the bearing product body. Although the font is very small, the products produced by regular manufacturers are printed with steel stamping technology, and they are pressed before being heat-treated. Therefore, although the font is small, it is deep and very clear. In general, the fonts of counterfeit products are not only fuzzy, but because of the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand or have serious hand marks.
Is there any noise?
Hold the bearing body sleeve with your left hand, and rotate the jacket with your right hand to rotate it. Due to the backward production conditions of most counterfeit products and completely manual workshop operation, impurities such as dust and sand will inevitably be mixed into the bearing body during the production process, so there will be noise or unsmooth operation when the bearing rotates . This is the key to judging whether the product comes from a brand product of a regular manufacturer that has strict production standards and is operated by a machine.
Whether there are muddy oil marks on the surface.
Whether there are muddy oil marks on the surface This requires us to pay special attention when purchasing imported bearings. Since the current domestic rust prevention technology is still a certain distance away from foreign advanced manufacturing countries, it is easy to leave thick oil marks when the bearing body is rust-proofed, and it feels sticky and thick when it is touched by hand. There is almost no trace of anti-rust oil on the imported bearings. According to industry insiders, particularly careful people can smell a special smell on imported bearings, which is the smell of anti-rust oil.
Is the chamfer uniform?
The so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical surfaces. Due to the production technology limitations, counterfeit bearing products are not handled satisfactorily at these corners. We can easily Identify.
