What is pu roller bearing?

In recent years, with the continuous development of industry, bearings have been more and more widely used by society. Among them, pu roller bearing is mainly used in some precision instrument industries. Pu roller bearing refers to the injection or bonding of rubber products in the bearing, pu roller bearing The production process requires the use of casting tools.
　Pu roller bearings are used after encapsulation. Bearing encapsulation can make the service life of the bearing longer and more in line with the request.
　　
pu roller bearing features: excellent strength and wear resistance, heat resistance, hydrolysis resistance, aging resistance, bright appearance, fine and smooth colloidal surface, strong adhesion of colloidal material and shaft core; wide hardness range, hardness The range is Shore A15-D80. The polyurethane rubber roller has good chemical properties, good solvent resistance, aging resistance, tear resistance and good resilience.

　　
Where can I buy pu roller bearing?
　　
　　 Some friends who need to buy or purchase pu roller bearings may not know where the bearing wholesale market or manufacturer is, or do not know how to buy the cheapest bearing. These are all because of the poor information that most people are confused when buying bearings. In fact, this is the case in many industries. In the case of poor information, the prices of products in each place are different. It is also because of the channel that the price of the bearing is different. The following introduces you to several common methods for identifying the quality of rubber bearings:
　　
　　 1. Is the outer packaging clear:
　　
　　 Under normal circumstances, the Zhengchang brand has its own dedicated designer to design the external packaging, and arrange the production conditions of the factory to produce the production, so the packaging from the line to the color block is very clear and unambiguous.
　　
　　 2. Is there any noise:
　　
　　 Hold the pu roller bearing inner ring with your left hand, and turn the jacket to rotate it with your right hand, and listen to whether there is any noise. Due to the backward production conditions of most counterfeit products, completely manual workshop-style operation, it is inevitable that impurities such as sand will be mixed in the production process and hidden in the pu roller bearing body, so it will make a noise when rotating. This is the biggest difference from a genuine factory brand that strictly enforces production standards and operates on machines.
　　
　　 3. Whether the steel printing is clear:
　　
　　The brand words and labels will be printed on the pu roller bearing body. The font is very small, but most of the products produced by the factory use steel stamping technology, and they are embossed before being heat-treated. Therefore, although the font is small, it is deep and very clear. The fonts of counterfeit products are not only vague, because of the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand.
　　
　　 4. Is there any turbid oil on the surface:
　　
　　 This should be paid special attention when purchasing imported bearings. Since the current anti-rust technology in China is not particularly home, it is easy to leave thick oil marks on the bearing body when it is anti-rust treated, which is sticky and thick on the hand, but it is hardly seen on the bearings imported from abroad. When it comes to the traces of anti-rust oil, the attentive expert said that the imported bearings smelled a bit. They must have been under anti-rust oil, but they were just not visible.
　　
　　 5. Whether the chamfer is uniform:
　　
　　 The so-called chamfer of the pu roller bearing, that is, the intersection of the horizontal and vertical surfaces. Due to the limitations of production technology, the counterfeit bearings are not handled satisfactorily at these corners.
