How to distinguish the real and false bearings and imported bearings, bearing types, please consult

Now the bearings are very realistic, a large part of the situation you can not distinguish the real from the fake, only the bearing back to the factory for testing or ask a professional organization for testing, and then there is experience, some genuine goods you see more than a look, that is fake, or you fake you see more, see the appearance of this bearing is not bad, but do not be blinded by the appearance, to determine the quality of the bearing rest assured I concluded:

1. Determine your own incoming channels, whether you buy bearings from regular authorized stores, such as the three major factories Harbin, Wafangdian, Luoyang, including imported bearings, have representative offices in various regions, and direct sales centers. In Jinan, I know that the direct sales center of Harbin, at No. 30-1 Jiwei Road, the imported bearings also have an authorization next door to his house, and the others are not very clear.

2. Then there is that you use, in the case of ensuring the working conditions, you can distinguish the real and fake at a glance, it is recommended not to do this, time-consuming and laborious.

Hope it helps.

Generally, the appearance of the bearing, the finish of the bearing material, and there is no need to be greedy for cheap, find a regular dealer to buy.

Hello, this distinction is generally only available to people in the industry, but one thing is very important.

Second: ask the other party to issue a quality assurance certificate, such as a one-month replacement, one year of quality assurance, so that you can avoid buying fake and shoddy bearings, because counterfeit bearings will be broken in a few days.

Three: to buy imported bearings, you need to choose a better brand, but their ** is relatively high, such as: FAG, SKF, etc.

If you have any related questions, please ask, I am a sales engineer who sells imported bearings, pure handmade, thank you for adopting!

How to distinguish the authenticity of imported bearings, everything is true and false, of course, imported bearings are no exception to pirated, copycats, parallel goods and other products, because it is imported bearings, so compared with domestic bearings, the probability of counterfeiting and shoddy bearings is relatively high, so how to distinguish the authenticity of imported bearings has become an urgent problem to be solved. There are many kinds of counterfeiting means, how to distinguish the authenticity of imported bearings, we have to beware of some common cost means, such as shoddy bearings, counterfeit famous manufacturers of internal and external packaging and certificates, good goods and then mixed with some fakes, etc., these deceptive means are often used by bearing counterfeiters.

Then the next is how we want to distinguish the authenticity of the imported bearing, which also has some tips, first of all, we have to observe whether the steel seal on the imported bearing is clear, the real imported bearing steel seal is concave deep, is very clear. How to distinguish the authenticity of the imported bearing, followed by the need to see whether the bearing body of the imported bearing rotates to see whether impurities make a sound in the bearing body, if there is a fake. How to distinguish the authenticity of the imported bearing, and then see if the surface of the imported bearing is turbid and put in the oil stains, some are fake, and vice versa is true.

The reason why imported bearings are so fierce is that the interests of individual dealers are driven, but as long as you carefully identify these counterfeiters, there is no need for them to exist, very simply, the product can not be sold. How to distinguish the authenticity of imported bearings, imported bearings to go to regular manufacturers to buy, but also to see whether the company's reputation is good or not, do not buy fake imported bearings because of greed. The bearings of our factory are purchased from Jinan Haokun Machinery Technology Co., Ltd., and we have cooperated for a long time, and the quality and service are very good.

1. Whether the outer packaging of imported bearings is clear.

Under normal circumstances, the imported bearings of the genuine brand have their own special designers to design the external packaging, and arrange the production conditions of the factory to produce and produce, so the packaging is very clear and unambiguous from the lines to the color block, and some imported brands of accessories are specially designed to protect their intellectual property rights.

2. Whether the steel stamp on the imported bearing is clear.

The imported bearing body will be printed with brand words, labels, etc. The font is very small, but most of the genuine products use steel stamping technology, and the lettering is pressed before heat treatment, so although the font is small, it is deeply concave and very clear. The font of counterfeit products is not only blurry, but due to the rough printing technology, the font floats on the surface, and some can even be easily erased by hand.

3. Whether there is any noise in the bearing body of the imported bearing.

Hold the bearing inner sleeve of the imported bearing with the left hand, and rotate the jacket with the right hand to listen to whether there is any noise. Due to the backward production conditions of most counterfeit products, it is inevitable that sand will be mixed into the production process due to completely manual workshop operation.

Child-like impurities are hidden in the bearing body, so they make a noise when they rotate. This is the biggest difference between the original brand that strictly implements production standards and operates with machines.

4. Whether there are turbid oil stains on the surface of the imported bearing.

This should be paid special attention when buying imported bearings. Because the current anti-rust technology in China is not particularly at home, it is easy to leave a thick oil stain when the bearing body is treated with anti-rust, and it is sticky and thick in the hand, while the original foreign ones.

There are almost no traces of anti-rust oil on the imported bearings, but particularly careful experts say that the imported bearings smell a smell, and they must be under the anti-rust oil, but they can't see it.

Remind everyone to buy imported bearings to choose some reputable, old dealers. For example, Guangzhou Uniben bearing. The company was established early and has a good reputation among customers.

It's not to hit you, it's all industry secrets, it's an expert among insiders, and no one will really tell you. Even many bearing sellers who are not professional in making imported bearings will not be able to distinguish themselves! All these methods you can find on the Internet are the fur of the fur and there is no use for it!

How to distinguish the real from the fake

1. Whether the steel seal is clear.

Each bearing product will be printed with its brand words, labels, etc. on the bearing product body. Although the font is very small, the products produced by regular manufacturers are printed with steel printing technology, and the font is pressed before heat treatment, so although the font is small, it is deep and very clear. Normally, the font of counterfeit products is not only blurry, but also floating on the surface due to the rough printing technology, and some can even be easily erased by hand or have serious manual marks.

2. Whether there is noise.

Hold the inner sleeve of the bearing with the left hand, and rotate the outer sleeve with a small reciprocating amount with the right hand to listen to whether there is any noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products and the complete manual workshop operation, it is inevitable that impurities such as dust and sand will be mixed into the bearing body during the production process, so there will be noise or poor operation when the bearing rotates. This point is the key to judge whether a product comes from a brand product of a regular maker which has a strict production standard and operates with a machine.

3. Whether there are turbid oil stains on the surface.

Whether there are turbid oil stains on the surface, which requires us to pay special attention when buying imported bearings. Because there is still a certain gap between the domestic anti-rust technology and foreign advanced manufacturing countries, it is easy to leave a thick oil stain when the bearing body is treated with anti-rust, and it feels sticky and thick when touched by hand, while there is almost no trace of anti-rust oil on the bearing imported from abroad. According to industry insiders, particularly careful people can smell a special smell on imported bearings, which is the smell of anti-rust oil.

4. Whether the chamfer is uniform.

The so-called chamfer of the bearing, that is, the junction of the horizontal plane and the vertical surface, the counterfeit bearing products due to the limitations of production technology, in these corners and corners of the parts are not satisfactory, which we can easily identify.

5. Bearing packaging.

After the inner packaging and outer packaging bearings are manufactured and inspected, they are cleaned and anti-rust treatment, and then put into the inner packaging to achieve waterproof, moisture-proof, dust-proof, impact-proof, maintenance of the quality and accuracy of the bearings, as well as the purpose of convenient use and sales.

The inner packaging of the bearing is divided into three categories according to the anti-rust period:

Short anti-rust period packaging: anti-rust period of 3 to 6 months, suitable for large quantities of shipments to the same subscriber, short-term put into use bearings. By agreement between the two parties, simple packaging is adopted for the principle of convenience of use.

General anti-rust period packaging: anti-rust period of one year, suitable for general purpose bearings.

Long anti-rust period packaging: two years anti-rust period, suitable for special and precision bearings.

The inner packaging materials of the bearing include polyethylene plastic cylinder (box), kraft paper, plain and wrinkled polyethylene composite paper, paper box, polyethylene or polyethylene plastic film, nylon fastening tape or plastic braided fastening tape, waterproof and high-strength plastic tape, burlap bag, etc. The above materials need to ensure that the corrosion resistance test of the material is qualified.

What bearings are fake, you can't tell the real from the fake, the real ** business will also sell fakes, so, the bearing only the length of the use time, no real fake, what brand big, what bearing sells well, there will be fakes, the bigger the brand fakes, the more dealers are not experienced and can not distinguish, now most of the dealers in the country can distinguish SKF fakes, if you are the end user, then you must not be able to distinguish. If you really want to distinguish the real from the fake, there is only one way, find someone from the manufacturer to tell the difference.

1. Look at the SKF bearing logo. Some regular parts are marked with certain marks, such as gear marks such as gear marks, top marks and other assembly marks, which are used to ensure the correct installation of the parts, and those that do not have can not be purchased.

2. Look at the color of SKF bearings. Some original parts are specified with a certain color on the surface, and if they encounter other colors, they are counterfeit and shoddy parts.

3. Look at the appearance of SKF bearings. The appearance of the original parts is clear and regular, while the appearance of counterfeit products is rough.

4. Look at the paint. Unscrupulous businessmen will simply process waste parts, such as dismantling, assembling, patching, scraping, painting, etc., and then pass them off as qualified products** to illegally obtain high profits.

5. Look at the texture of SKF bearings. The materials of the original parts are qualified materials according to the design requirements, and the counterfeit products are mostly replaced by cheap and inferior materials.

6. Look at the gaps. Regular assembly components must be complete and intact to ensure smooth installation and normal operation. Some small parts on the assembly parts are missing, generally "parallel goods", which causes difficulties in installation.

Often due to the shortage of individual small accessories, the entire assembly parts are scrapped.

7. Look at SKF bearing storage. If there are problems such as dry cracking, oxidation, discoloration or aging of auto parts, it may be caused by poor storage environment, long storage time, poor material itself, etc.

8. Look at SKF bearing engagement. If the clutch plate rivet is loose, the brake hose is degummed, the electrical parts joint is unwelded, and the seam of the paper filter element is disconnected, it cannot be used.

9. Look at the packaging of SKF bearings. The packaging of original accessories is generally more standardized, unified standard specifications, and the printing is clear and formal, while the packaging and printing of counterfeit products are relatively poor, and it is often easy to find flaws in the packaging.

10. Look at the SKF bearing process. Although the appearance of inferior products is sometimes good, due to poor manufacturing process, it is prone to cracks, sand holes, slag inclusions, burrs or bruises. The cylinder gasket is extruded and deformed, which is easy to cause ablation due to poor sealing and ablation, resulting in oil leakage, air leakage and water leakage. The working surface of the piston and piston ring has burrs and is easy to pull the cylinder.
