As the domestic car ownership continues to rise, the use of auto parts and automotive supplies demand is also increasing, however, guangzhou city, large and small parts and supplies management store multiple and complex, the goods the good and bad are intermingled, mixed with a lot of fake and inferior products, thereby causing loss to the owner's, serious can even lead to personnel casualties.In order to let the owner of the factory brand of accessories and supplies have a certain understanding of the characteristics, from this week on the owner of the layout of the special "smart consumption" column, to the owner of friends to introduce a variety of types, the main car brand accessories.I hope that with the development of the column, the concept of respecting the brand, putting an end to fake products and using authentic products can be deeply rooted in the hearts of people.This is our hope and the direction of our efforts.
It is no exaggeration to call the bearings the joints of a car.In a car, not only its four legs -- wheels need to use bearings, every rotating machine parts are involved in the bearing, it is a very small but important thing in the transmission system.Because of the heavy workload, its wear is also relatively high, so the replacement of bearings is a common thing in car maintenance.Walk in the auto parts market, found that operating a variety of brands of bearing stores as many as cattle, but how they sell the quality of the bearings, whether the packaging is really marked on the factory brand?This question is probably in the heart of every car owners have been around many times.Here are some common ways to tell the quality of a bearing:
Packaging is clear: in general, the factory brand has its own special designers to design the external packaging, and arrange the production conditions of the factory to make production, so the packaging is very clear from the line to the color block, no ambiguity.(some parts of the imported brand accessories have special design to protect their own intellectual property rights, which will be introduced in detail in the future.)
Whether the stencils are clear: the bearing body will be printed with the brand name, label, etc.The font is very small, but most products are made with stenciled printing technology and are embossed before overheating, so the font is small, but deep and clear.And the font of the counterfeit product is not only blurred, due to the printing technology is rough, the font is floating on the surface, and some can even be easily wiped away by hand.
Whether there is noise: the left hand holds the bearing body sleeve, the right hand moves the jacket to rotate it, listen to whether there is noise.Due to the backward production conditions of most counterfeit products, completely manual workshop operation, in the production process will inevitably be mixed with sand and other impurities, hidden in the bearing body, so when rotating will produce noise.This is the biggest difference from a factory brand that strictly enforces production standards and operates with machines.
Whether there are muddy oil stains on the surface: this should be paid special attention to when purchasing imported bearings.Due to the current domestic antirust technology is not particularly home, so the antirust processing was carried out on the bearing body and is easy to leave the thick oil stains, holding the thick thick, and imported from abroad can hardly see the trace of anti-rust oil bearing, is particularly careful expert said imported bearing smell a smell, must be under the anti-rust oil, just can't see.
Chamfering is uniform: the so-called bearing chamfering, that is, the horizontal surface and vertical surface of the junction, the counterfeit bearing due to the production of technical restrictions, in these corners of the parts are not satisfactory.
