How To Distinguish The Original Bearing From The Fake Bearings.
Jul 13, 2018

How to distinguish the original bearings from the fake bearings


1 Whether the outer packaging is clear:

Under normal circumstances, the factory brand has its own special designer for the external packaging, and arrange the production conditions of the factory to produce, so the packaging is very clear from the line to the color block, unambiguous.


2 Is there any noise:

Hold the inner sleeve of the bearing with your left hand, and turn the outer sleeve with your right hand to make it rotate to hear if it has noise. Since most of the counterfeit products could be in bad  production conditions , it is inevitable that impurities, such as sand, will be incorporated into the bearing body during the production process, so that noise will be generated when rotating. This is the biggest difference between a factory brand that strictly enforces production standards and operates with machines.


3 is the printing of steel clear:

Brand letters, labels, etc. will be printed on the bearing body. The font is very small, but most of the products produced by the factory use the stencil technology, and the type is pressed before the heat treatment, so the font is small, but the recess is deep and very clear. The fonts of counterfeit products are not only blurred, but because of the rough printing technology, the fonts float on the surface, and some can even be erased by hand.


4 Is there any turbid oil on the surface:

This should be especially noted when purchasing imported bearings.  For the bad quality bearing, it is easy to leave a thick oil trace when the bearing body is rust-proofed, and it is sticky and sticky on the hand, and the bearings imported from abroad are almost invisible. To the traces of anti-rust oil, it is particularly careful and if smell it, it is definitely anti-rust oil, just can't see it.


5 Whether the chamfer is uniform:

The chamfer of the bearing, that is, the intersection of the horizontal surface and the vertical surface, the counterfeit bearing is unsatisfactory in the processing of these corners due to the limitation of production technology.
