1.Outside the packaging is clear :
In general, are factory brand has its own dedicated external packaging designers to design, and arrange for clearance of the plant production conditions of production, so in terms of packaging lines to color are very clear, unambiguous.
2. The word is clear :
Bearing in the body will be printed with the brand name, label, etc.. The font is very small, but the plant is produced most of the use of stamping technology, but without the heat-treatment is carried out before the embossing, so the font is small, but concave - deep, very clear. The font counterfeit products not only because of printing technology, fuzzy, rough, font floating on the surface, some even can be easily wiped off by hand.
3.Whether there is noise:
The left hand holding the body bearing sleeve, right hand toggle coat make their rotation, listen to whether there are miscellaneous ring. As most of the backward condition of counterfeit products is completely manual workshops, in the production process will inevitably be the impurity in the sand - like, hidden in the bearing body, so rotation will be issued when the noise. This is the biggest difference between the standard of production and the factory brand that is used in machine operation.
4.Whether the surface traces of muddy :
This should pay special attention to the purchase of imported bearings. Because of the current anti rust technology is not at home, so the bearing body for rust prevention processing is easy to leave a thick grease, in the hand - sticky stiff, and the bearing of foreign imported almost can not see the traces of rust preventive oil, it is particularly careful imported bearings smell experts say there is a kind of taste, is certainly the antirust oil, just impossible to see.
5. The chamfer is uniform :
The so-called bearing chamfer, that is horizontal and the vertical surface junction, counterfeit bearings due to the constraints of production technology, processing is not so satisfactory in these corners of the site.
