How to correctly identify the authenticity of zwz bearings

Each specific physical product of zwz bearing has its own performance and characteristics, which are given before it leaves the factory. So it is necessary for us to understand and recognize it:
 
a. Recognize product design:
 
For example, zwz bearing spherical roller thrust bearing is equipped with a large number of asymmetric rollers, and the specially designed raceway has the best consistency. As a result, they are able to withstand heavy axial loads and allow operation at higher rotational speeds. Bearings with designation suffix E are fitted with a stamped steel window cage which forms an inseparable assembly with the rollers and the shaft washer. For E-type bearings with stamped steel cages, the inner bore of the housing must be widened to prevent the cage from rubbing against the housing in the event of a misalignment of the shaft. To put it bluntly, this design ensures high bearing capacity, high performance and long life. Each brand of type bearing has design characteristics, and it is necessary to know more about them.
 
b. Know the production and process of products:
 
We generally do not have so many opportunities to actually see the production of products, but some factories may show them to everyone through CD projections or videos during training or exhibitions. For physical products, we still have the opportunity to see the surface craftsmanship of the product, such as chamfering craftsmanship, end face craftsmanship, and logo craftsmanship. Only by truly understanding these correct craft marks can it be possible to distinguish the fake ones.
                                                                                                                        
 
c. Know the name of the product:
 
The naming of each brand's standard product model has certain specifications. There are certain similarities between major brands, but also their own differences. Some are reflected in different prefixes, and some basic models are different. More It is reflected in the difference in the order, method and meaning of the suffixes. Only by recognizing these differences can we know the correct representation method and practical significance of a brand's specific bearing model. If the zwz bearing is represented as a zwz bearing, there must be something wrong. These all require long-term accumulation and summary.
 
d. Know the packaging of the product:
 
The packaging of each specific bearing is specially designed and marked. From the packaging material, to the packaging color, style, logo, anti-counterfeiting, environmental protection, as well as product safety, transportation convenience and other aspects, there will be a full range of design and Consider, and the color, style, logo, and anti-counterfeiting of product packaging in different periods may be different. For example, the recent outer packaging of zwz bearings is wooden environmental protection packaging, and the inner packaging is moisture-proof paper plus polyester tape, etc. Maybe this packaging will change again at a certain period in the future, and the anti-counterfeiting and logo will also change, and SKF will not notify you in particular. you. Only by knowing and understanding these differences and changes can it be possible to identify fake and inferior counterfeit products.
 
Of course, these understandings are only superficial understandings. To have an essential understanding, it must be identified by the relevant departments of the relevant manufacturers or professional product certification agencies, and the nature may change.
 
In a word, if you want to distinguish the authenticity, you can only make the difference by knowing more about the characteristics and performance of the "genuine" bearing, and there is no other way.
