What are the ways to distinguish bearings

It is not too much to call bearings joints in cars. In a car, not only the wheel needs to use bearings, but also the bearing participation of all the parts of the machine that will change. It is very important but very serious in the transmission system. Because of the large amount of work and high wear degree, it is a common work to replace bearings in automobile repair. Here are several common ways to distinguish the quality of bearings from you:

Whether the outer packaging is clear: generally, the brand of the factory has a special personal description personnel to describe the external packaging, and organize the factories with the production conditions to produce the products. Therefore, the packaging is clear and unambiguous from the line to the color block. Some imported brands have a common description of the intellectual property rights specially used to protect individuals. This will be analyzed in the future.

Whether the steel printing word is clear: the bearing body will be printed with brand words, mark, etc. The font is very clear. But the counterfeit product font is not only vague, because the printing skills are rough, the font floats on the surface, some and even easily can be erased by hand.

Whether there is noise: hold the bearing sleeve in the left hand, and move the jacket with the right hand to make it rotate to hear if there is noise. Because the production conditions of some of the counterfeit products are backward, the workshop operation is complete, and the impurities such as sand will be added in the production process, which is hidden in the bearing body, so the noise will be announced when rotating. This is the biggest difference between the factory brands which strictly implement the production specifications and operate by machines.

Whether there is dirty oil on the surface: this should be paid attention to when purchasing imported bearings. Because the current anti rust skills at home are not common, it is very simple to leave thick oil traces when dealing with bearing body rust prevention, stick thick on the hand, while the foreign original imported bearings can hardly see the traces of rust proof oil, but the experts who are jointly careful say that imported bearings smell a taste, and it must be rust proof oil, only can not be seen.

Whether the chamfer is even: the so-called bearing chamfer, that is, the intersection of the horizontal and vertical surfaces, the counterfeit bearing is not disposed well in the corner of these corners due to the constraints of production skills.
