Automobile bearings generally use imported bearings, so the imported automotive bearings are still very good, the quality is very good, domestically produced automotive bearings are relatively cheaper, and now many imported bearings are of good quality, such as NSK imports. Bearings and FAG bearings, as well as SKF bearings are suitable for automotive bearings.
With the continuous increase in the number of domestic car ownership, the demand for the use of auto parts and auto accessories has also increased. However, there are many large and small parts and accessories stores in China, and the goods are mixed. Many counterfeit and shoddy products are mixed. , causing the loss of the owner, and even serious people may even cause casualties.
In order to let the owner have a certain understanding of the characteristics of the accessories and supplies of the various factory brands, introduce the identification methods of various types and accessories of major automobile brands to the owners of the owners.
It is no exaggeration to call a bearing a joint of a car. In a car, not only its four legs - the wheels need to use bearings, but the machine parts that will rotate are indispensable for the participation of the bearings, it is a very inconspicuous but significant thing in the transmission system.
Because of the large amount of work, its wear is also relatively high, so replacing bearings is a common thing in car maintenance. Walking in the auto parts market, we found that the bearing stores that operate various brands are like a lot of hair. However, the quality of the bearings they sell is really the same as the brand on the packaging. This question probably wandered many times in the hearts of every car owner. Here are a few common ways to identify the quality of a bearing:
Whether the outer packaging is clear:
Under normal circumstances, the factory brand has its own special designer to design the external packaging, and arrange the production conditions of the factory to produce, so the packaging is very clear from the line to the color block, unambiguous.
Whether the steel printing is clear:
Brand letters, labels, etc. will be printed on the bearing body. The font is very small, but most of the products produced by the factory use the stamping technology, and the type is pressed before the heat treatment, so the font is small, but the recess is deep and very clear. The fonts of counterfeit products are not only blurred, but because of the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand.
Is there a noise:
Hold the inner sleeve of the bearing with your left hand and turn the outer sleeve with your right hand to make it rotate to hear if it has noise. Since most of the counterfeit products are out of production conditions and completely hand-worked, it is inevitable that impurities such as sand will be incorporated into the bearing body during the production process, so that noise will be generated when rotating. This is the biggest difference between a factory brand that strictly enforces production standards and operates with machines.
Is there any turbid oil on the surface:
This should be especially noted when purchasing imported bearings. Since the current domestic anti-rust technology is not particularly good at home, it is easy to leave a thick oil trace when the bearing body is rust-proofed, and it is sticky and sticky on the hand, and the bearings imported from abroad are almost invisible. To the traces of anti-rust oil, it is particularly careful that the imported bearings smell a smell, and it is definitely anti-rust oil, just can't see it.
Whether the chamfer is uniform:
The so-called chamfering of the bearing, that is, the intersection of the horizontal surface and the vertical surface, the counterfeit bearing is unsatisfactory in the processing of these corners due to the limitation of production technology.
