Common method of automotive bearing quality


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 about accessories and supplies have a certain understanding of the characteristics, from this week in the owner of the layout of the special "smart consumption" column, to the owners of friends introduce a variety of types, the main car brand accessories of the way to identify.I hope that with the development of the column, the concept of respecting the brand, eliminating fake products and using authentic products can be deeply rooted in the hearts of people.This is our hope and our direction. 

It is not too much to call the bearings the joints of a car.In a car, not only its four legs -- wheels need to use bearings, but all the rotating parts of the machine are involved in the bearing, it is a very small but important thing in the transmission system.Because the workload is large, its wear is also relatively high, so the replacement of bearings is a common thing in car maintenance.Walking in the auto parts market, found that operating a variety of brands of bearing stores as many as cattle, but they sell the bearing quality, whether it is true as the packaging label is the brand?This question is probably in the heart of every car owners have been around many times.Here are some common ways to identify bearing quality:

Packaging is clear: in general, the factory brands have their own special designers for external packaging design, and arrange production conditions of the factory for production, so the packaging is very clear from the line to the color block, no doubt.(some imported brands have unique designs on the packaging of accessories to protect their intellectual property rights, which will be introduced in detail in the future). 

Whether the steel print is clear: the bearing body will be printed with brand words, label number, etc.The typeface is very small, but most products are made with stenciled printing technology, and the typeface is pressed before it is overheated, so the typeface is small, but deep and clear.And the font of the counterfeit product is not only fuzzy, because the printing technology is rough, fonts float on the surface, 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 and manual workshop operation, impurities such as sand will inevitably be mixed in the production process and hidden in the bearing body, so it will produce noise when rotating.This is the biggest difference between a factory brand and one that strictly enforces production standards and operates on machines. 

Whether the surface is muddy traces: this should be paid special attention to when buying 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 interface, the counterfeit bearing due to the production of technical restrictions, in these corners of the parts are not satisfactory.
