Whether the packaging is clear: Under normal circumstances, the factory brand has its own special design staff to design the external packaging, and arrange the production conditions of the factory for production, so the packaging from the line to the color block are very clear, unambiguous , Part of the import brand of accessories on the package there are specifically designed to protect their own unique intellectual property design.

Steel printing is clear: the bearing body will be printed on the brand words, labels and so on. The font is very small, but most of the products are produced by the use of stamping technology, and before the heat treatment before the pressure word, so the font is small, but concave deep, very clear. The counterfeit product font is not only blurred, because the printing technology is rough, the font floating on the surface, and some even easily can be wiped out by hand.
Whether there is a noise: the left hand holding the bearing sleeve, right hand toss the jacket to rotate, listen to whether there is a noise. As most of the counterfeit products production conditions behind, completely hand-workshop operation, in the production process will inevitably be mixed with a class of impurities in the sand, hidden in the bearing body, so when the rotation will be issued a noise. This is the biggest difference between the strict implementation of the production standards and the operation of the machine.
Whether the surface of turbid oil traces: This should be paid special attention in the purchase of imported bearings. As the current domestic anti-rust technology is not particularly home, so the anti-rust treatment of the bearing body is easy to leave a thick oil traces, holding in the sticky sticky thick, and foreign imports of bearings almost can not see To the traces of rust-proof oil, it touches on a particularly careful expert said that the imported bearings smell a taste, certainly under the anti-rust oil, just do not see it.
Chamfering is uniform: the so-called bearing chamfer, that is, the intersection of the horizontal and vertical, counterfeit bearings due to the limitations of production technology, in these corner of the corner of the deal was unsatisfactory.
