The packaging is clear. In general, the positive plant has its own special brand of foreign designer packaging design, production conditions, and arrangements for clearance of factory production of production, and therefore in terms of the packaging lines to colour is obvious, unambiguous, some imported brands on the packaging there is a special accessory to protect their intellectual property unique design. Is there any noise Left hand holding the bearing sleeve body, right-hand toggle coat rotated, and whether they have a hybrid ring. Since most production conditions behind counterfeit products, entirely hand-workshop-style operations in the production process will inevitably be a kind of impurity mixed into the sand, hidden in the bearing body, so when the rotation will be issued hybrid ring. This is strictly enforced and between production standards, and with the operation of the machine is factory brand the biggest difference. If a uniform chamfer The so-called bearing chamfer, i.e., the junction of the horizontal surface and the vertical plane, the bearing counterfeit due to limitations of the production technology, in these parts of the corners handled unsatisfactorily. The symbol word is clear. The bearing body will be printed with the word brand, labels, and so on. The font is tiny, but most are factory produced using the stamp technique, and before the heat-treatment is carried out without the word pressure, the font may be small, but a deep concave, very clear. The counterfeit products not only blurred the font because of the rough printing technology, and fonts floating on the surface, but some of them can also be easily wiped off by hand. The surface is muddy with traces of oil. This should be especially careful when buying bearings. It is easy to leave thick oil stains because many small factories' rust-proof technology is not professional, so the body-bearing anti-rust treatment, in our hands sticky thick, and we could barely see the rust on the bearing TFL Traces oil. Finally, while the bearing is fake a lot, as long as we choose the regular procurement channels, with the ability to identify the basic bearing and awareness, we will be able to purchase authentic bearings and avoid being taken cheated, to avoid unnecessary economic losses.
