I have always thought this way: To identify whether an object is a "truth", the first problem is that you have to "know the real thing." In other words, you need to understand and understand and study the "truth", to know its past, present, and future, to know its appearance, but also to know his inner. Only by understanding the real thing from the inside out, from all directions, can you expose a "pseudo-product" in front of you, point out where it is "fake", say why it is fake, and avoid unnecessary trouble. And loss.
So how do you come to "know the real thing"?
1. Look at the SKF bearing logo. Some regular parts are marked with some marks, such as the top mark of the gear mark, etc., to ensure that the parts are properly installed, and no one can not be purchased.
2, look at the SKF bearing color. Some original parts have a certain color on the surface, and if they are other colors, they are fake and shoddy parts.
3, look at the appearance of SKF bearings. The original parts have a clear print or cast and mark, and the counterfeit products have a rough appearance.
4. Look at the paint. Unscrupulous traders will process the waste parts through simple processing, such as dismantling, loading, spelling, scraping, painting, etc., and then pretending to sell the qualified products, illegally obtaining 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 made of cheap and inferior materials.
6, look at the missing. Regular assembly components must be in good condition to ensure smooth installation and normal operation. Some small parts on some assembly parts are missing, usually "parallel imports", which makes installation difficult. Often due to the shortage of individual gadgets, the entire assembly is scrapped.
7. Look at SKF bearing storage. If the auto parts are cracked, oxidized, discolored or aged, they may be caused by poor environment, long storage time, and poor materials themselves.
8, see SKF bearing joints. If the clutch plate rivet is loose, the brake pipe is degummed, the electrical parts are unsold, and the paper filter joint is disconnected, it cannot be used.
9, look at SKF bearing packaging. The original parts packaging is generally more standardized, unified standard specifications, printed and written clearly and regular, and counterfeit products packaging and printing is relatively crude, often can easily find flaws from the packaging.
10. Look at the SKF bearing process. Although the appearance of inferior products is sometimes good, but due to poor manufacturing process, cracks, sand holes, slag inclusions, burrs or bumps are prone to occur. The cylinder head is squeezed and deformed. When used, it is easy to cause the seal to be abrupt and ablated, resulting in oil leakage, air leakage and water leakage. The working surface of the piston and piston ring has burrs and easy to pull the cylinder.
