Many performance characteristics of plastic and metal bearings compared to access in a wide range of applications, but some of the inherent characteristics of the plastic also make it in the bearing application shall not be given full consideration. Such as the relatively low strength, poor hardness, thermal expansion coefficient is much larger than metals, low thermal conductivity, thermal conductivity is poor, heat distortion temperature is lo...
Plastic bearing cage in a wide range of applications, has highlighted the application of plastics in the superiority of rolling bearings. With modern technology, the successful development of new materials, plastic and extends the scope of application for plastic applications in the further development of rolling space.
1), bearing cage has plastic from PA66/GF, gradually began to use PTFE, PTFE / GF, PEI, PVDF, PEEK / GF, PEEK / CF, PPS, PI, U...
Rolling bearing is a mechanical drive an important and indispensable part in it for improving the transmission efficiency, reduce energy consumption plays an irreplaceable role.
In the modern bearing technology development process, to improve the bearing capacity, to optimize the design, use of new materials, new technologies. Plastics, engineering plastics and special engineering plastics in particular, have increasingly shown their superiority...
Plastic bearing POM, PP plastic bearing POM and PA material with good mechanical strength and wear resistance, suitable for production of more sophisticated plastic bearings, working temperature from -60 ℃ ~ 100 ℃, high strength and smooth surface, basically does not appear tension, its good self-lubricating properties and low coefficient of friction, while maintaining the traditional advantages of plastic bearings on the basis of precise an...
High-performance plastic bearings are often modified by the self-lubricating plastic processing, plastic bearings coefficient of friction at work directly affects the size of the life of the bearing and the size of the required driving force, and the direct result of the high and low temperature equipment and instruments, Therefore, the bearing friction coefficient is of great concern to the ball bearing design engineers a performance parameter....
Currently used can generally be divided into the rolling bearings and ball bearings; rolling and sliding bearings works by name can be distinguished, Rolling friction occurs when the work is rolling friction, and sliding bearings occurs when the work is sliding friction; rolling friction depends on the size and manufacturing precision; and bearing friction depends on the size of the bearing sliding surface of the material. Bearing face generally...
