Our bearing professions can't be separated from the practice of this society; we also have to face the authenticity of the bearing every day. Remember the short essay I wrote, "Identify the Basics of Counterfeit Goods"; that is microscopic, general direction Tips or hints for your pre-sales action.
So; how to distinguish the authenticity of the detailed bearing? This is a problem that is often seen in forums; it is also a problem that many famous brothers often ask me on MSN or QQ; it is also a problem that sometimes makes me confuse! I think this problem is too big; it is really impossible to simplify Donsie. To be honest! This is also a puzzle that has always puzzled me! I am doing my best every day to figure out the problem. With such a problem; let me discuss it with us.
I always thought this way: I want to distinguish whether an object is a "truth"; the first problem is that you have to "know the true thing." In other words, you must know and know and discuss "truth"; you must know its past, now, In the future; you must know its appearance; you must also know his connotation. As long as you understand the "pseudo-product" from the inside out, you can poke a "pseudo-product" that is placed in front of you; Where is it; say why it is false; prevent unnecessary trouble and loss.
So; how come "know the real thing"?
Here's how to know the "true bearing"; put forward my thoughts.
Each brand bearing detailed product has its own functions and features; this is what it gave before leaving the factory. So we need to know and know it:
1. Know the producer of the product:
For example: SKF/29434E; this is a spherical roller thrust bearing produced by SKF Group in Sweden bearing factory. Here you have to know and know the status of SKF Group and its Swedish factory. Know the history and current status of SKF , product scale, development, shopping malls and other common sense; know its strengths, weaknesses, brand awareness, brand credibility, quality, price, price and so on. Of course, the more you know the better; the deeper the better, also Know what types of products are produced in the Swedish factory. If someone sells SKF/NU328ECJ bearings to SKF Sweden, you should be vigilant. Because; as far as I know; this bearing is in SKF Germany factory Produced.
2. Know the business of the product:
Know the situation of the operator of the bearing you purchased. For example, he is the agent or the dealer; the authorized dealer is still the usual dealer; it is still the way to go; it is your promise. The merchant is still the first collaborator; he must know and know about him; this is very important to ensure the quality of the original brand and the price of your product. If the operator who sells this bearing says personally It is "SKF authorized dealer"; and together said that the individual is a FAG or NSK or NTN bearing distributor; then you must not trust! Because "SKF authorized dealers" can not be authorized to distribute other brand products together; similar to these have a guiding effect on knowing your products.
3. Know the product:
a. Know the description of the product:
For example, SKF/29434E spherical roller thrust bearings are equipped with many asymmetric rollers; the uniquely depicted raceways have the best consistency. Therefore, they can accept very heavy axial loads; and allow higher speed operation. Type suffixes Bearings for E; equipped with a stamped steel window-type holder; components with rollers and shaft rings that are not separate. For E-type bearings with stamped steel holders; it is necessary to widen the inner bore of the housing; avoid adhering to the frame The conflict with the bearing housing in the case of misalignment of the shaft. This depiction ensures high bearing capacity and high functionality of the bearing as well as long life. Each type of bearing has a depiction of the characteristics; to know more and know them. .
b. Know the production and process of the product:
The production of the products; they are usually not seen in so many times of practice; but some factories may be in training or exhibition; show them through CD projection or video. For the product of the matter; we are still watching Appearance to the product; such as chamfering process, end face process, marking process, etc.; these processes are usually; different brands have zones; it is worth deepening knowing and knowing. As long as you know the correct craft logos; Can distinguish between fake.
c. Know the name of the product:
The naming of each brand standard product type has certain standards; the major brands have certain similarities; they are different; some are reflected in different prefixes; some basic types are different; More is reflected in the suffix indicating the order and method and the meaning is different. As long as you know these different; can understand the correct indication of the brand's detailed bearing type and practical meaning. If SKF/29434E is indicated as SKF / 29434 or SKF/29434J; that must be difficult. These require long-term accumulation and summarization.
d. Know the packaging of the product:
The packaging of each detailed bearing is uniquely depicted and identified; from the raw materials of the packaging; to the color, style, logo, anti-counterfeiting, environmental protection of the packaging; as well as a comprehensive description of the product safety, transportation convenience and so on. Thinking; and the color, style, logo, anti-counterfeiting of the product packaging may be different. For example, the recent outer packaging of SKF/29434E bearing is wooden environmental protection packaging; the inner packaging is moisture-proof paper plus polyester tape; The package can be changed in a certain period of time; anti-counterfeiting and logos have also changed; SKF will not tell you uniquely. As long as you know and know these differences and changes, you can distinguish between fake and inferior products.
Of course; these know the external appearance; to know the substance; it must be judged by the associated part of the associated manufacturer or the product of the professional product; the nature can change.
Always want to distinguish between true and false; you only need to know more and know the characteristics, functions and other information of the "real" bearing; you can make a distinction; there is no other way. I have been constantly piled up and learning myself; Sometimes the machine and more brand bearing cognitors communicate extensively in this area.
