The packaging is clear: Under normal circumstances, are factory brand has its own dedicated design staff external packaging design, and arrange for the production conditions to cross the border plant for the production of production, packaging in terms of lines to color are very clear and unambiguous .
Seal word is clear: INA Bearings body will be printed with the brand "label. The font is very small, but are factory produced mostly using the stamp technology, but also in the untreated embossing, so although the small font, but the concave deep, very clear. Font of counterfeit products is not only fuzzy, due to rough printing technology, fonts floating on the surface, and some even can hand erase.
Miscellaneous sound: left hand holding the INA bearing the body, right hand toggle coat to make it rotate, and listen to their hybrid sound. Backward production conditions of the majority of counterfeit products, completely manual workshops operating, in the production process will inevitably be braced with sand impurities, hidden in the INA bearing the body, so in the rotation when a hybrid ring. This is and strict enforcement of production standards, and the biggest difference between the machine operation is the brand.
Surface is muddy traces of oil: the purchase of INA bearings should pay special attention to.

Chamfer is uniform: the chamfering into the so-called INA Bearing is the horizontal surface and vertical surface of the junction, INA bearing counterfeit due to restrictions on production technology, the site of the rougher edges of handling unsatisfactory.
