Bearing quality identification

We usually identify the quality of equipment bearings from the following aspects:
1. Is the outer packaging clear
In general, brands produced by legitimate manufacturers have their own specialized designers to design external packaging, and arrange factories with qualified production conditions for production. Therefore, the packaging of products should be very clear and unambiguous from lines to color blocks.
2. Is the steel seal clear
Each bearing product will have its brand name, label, etc. printed on its body. Although the font is very small, products produced by legitimate manufacturers use steel stamping technology for printing, and they are pressed before being overheated. Therefore, although the font is small, it is deeply concave and very clear. In general, 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 or have severe hand marks.
3. Is there any noise
Hold the inner sleeve of the bearing with your left hand, and gently rotate the outer sleeve with your right hand to listen for any noise during the bearing operation. Due to the outdated production conditions of most counterfeit products and the complete manual workshop operation, impurities such as dust and sand may inevitably be mixed into the bearing body during the production process. Therefore, there may be noise or unsmooth operation when the bearing rotates. This is the key to determining whether the product comes from a reputable manufacturer's branded product with strict production standards and machine operation.
4. Surface
We should pay special attention to whether there are turbid oil stains on the surface when purchasing imported bearings. Due to a certain gap between domestic rust prevention technology and advanced manufacturing countries abroad, it is easy to leave thick oil stains when rust prevention treatment is carried out on the bearing body. When touched by hand, it feels sticky and viscous, and almost no traces of rust prevention oil can be seen on imported bearings. According to industry insiders, those who are particularly careful can smell a special smell on imported bearings, which is the smell of anti rust oil.
5. Is the chamfer even
The so-called chamfer of bearings refers to the intersection between the horizontal and vertical surfaces. Due to production technology limitations, counterfeit bearing products are not handled satisfactorily at these edges and corners, which we can easily distinguish.
