Bearing identification method

Many imported bearings how do we go tell? To tell you about:

The packaging is clear: Under normal circumstances, are factory brand has its own dedicated designer of external packaging design, production conditions and arrangements for making the production of the factory clearance, so in terms of packaging lines to color is very clear and unambiguous . (Some imported brands of accessories package also devoted to the protection of their intellectual property unique design, the content of which in the future will continue to carry out a detailed description).

Seal word is clear: the taper roller bearing body will be printed with the brand words, labels and so on. Font is very small, but most are factory produced using Seal technology, but without the heat-treatment is carried out before the word pressure, so the font was small, but a deep concave, very clear. The font counterfeit products not only blurred, because the rough printing technology, fonts floating on the surface, and some can even be easily wiped off by hand.

Is there a hybrid ring: left hand holding the sleeve bearing the body, right hand to rotate toggle coat, listen to whether there is a hybrid ring. As most of the counterfeit products behind the production conditions, completely hand-mill operation in the production process will inevitably distracted by a class of impurities in the sand, hidden in bearing the body, so the rotation will be issued when hybrid ring. This is strictly enforced and production standards, and with the machine operation is the biggest difference between brands.

Is there muddy surface traces of oil: This is the purchase of imported bearings should pay special attention. Because of the current anti-rust technology is not particularly home, so the bearing body rust treatment can easily leave traces of oil thick, sticky thick stick in your hand, and foreign imported bearings almost invisible the traces of rust oil, experts say that it touches especially careful bearing smells kind of taste, is certainly under anti-rust oil, but do not see it.

Chamfer is uniform: the so-called bearing chamfer, which is horizontal plane and the vertical plane of the junction, counterfeit bearings as restrictions on production technology, in which the corners of the site handled unsatisfactory.
