Instead, they have turned to malicious competition, smashing their peers, competing to lower sales prices, and repeatedly challenging the bottom line of bearing quality.

1 Use iron and carbon steel to make bearings (hardness is not enough) and repair scrap bearings (not enough precision). 2 Put the inferior bearing and small factory bearing on the trademark of Dachang, and counterfeit the inner and outer packaging and certificate of the famous big factory products. 3 Counterfeit famous manufacturers, distributors, agents, and even counterfeit manufacturers in the spot market. 4 Pretend to be a genuine bearing with a defective bearing. 5 Turn ordinary grade bearings into D-class bearings. 6 In the original goods, the counterfeit goods were imported. 7 Counterfeit goods sell genuine price, genuine sell D grade price, use fake price book. 8 Customers should give counterfeit goods when they want cheap goods, and give them original goods if they are of good quality.

How to identify counterfeit bearings It is very important to understand the brand and specifications of bearing products. It is very important to understand the brand of bearing products. Knowing some well-known bearing brands at home and abroad can effectively avoid the inferior bearing products of second-line small factories in the purchase process, and the products of big brands Word of mouth is also a good quality guarantee. Before making a brand selection, we must determine the specifications of the bearing products that we need. The proper bearing specifications can not only effectively extend the service life of the bearings, but also the most effective way to avoid safety accidents.

Choice of place of purchase

When the brand and product specifications are determined, it is the choice of the place of purchase. Here, you can recommend one or two different ways to buy a place. First, buy directly from the manufacturer of the bearing product. Second, because word of mouth credibility is a guarantee of the image of the company's market, it is also a very good way to buy agents or sales companies with good reputation and reputation.

Whether the outer packaging is clear

Under normal circumstances, the factory brand has a 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, some imported brand accessories There is also a unique design on the packaging to protect your intellectual property.

Is the steel print 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 any 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.

Bearing brother reminds you: careful and cautious, not greedy for small cheap

Finally, since the choice of bearing products, in careful and cautious, you should also avoid coveting small and cheap, so as not to lose more. The production of any product has a certain cost, and this cost is also the actual reason for determining the price of the product. It is called "a penny and a share", of course, bearing products are no exception. Therefore, the bearing products of well-known enterprises have very strict control in the production process from the selection of raw materials to the production process, and this is the basis for ensuring the quality of bearings. Because of this, the cost of the bearing product will also increase, so the bearing product with too low price will just expose its low quality prototype. In short, after a detailed understanding of the bearing product market, choose the right purchase channel, you will choose the right bearing products. Do not blindly pursue the price and ignore the quality!
