Non-metallic sliding bearings and metal sliding bearing differenc

    It occurs when the work is bearing sliding friction; rolling friction depends mainly on the size of the manufacturing precision; and bearing friction bearing material depends on the size of the sliding surface. Faces are generally plain bearings with self-lubricating function; non-metallic bearing material is divided according to the sliding metal bearings and plain bearings. Non-metallic sliding bearings are mainly plastic bearings, plastic bearings are generally used relatively good performance of engineering plastics; more professional manufacturers generally have self-lubricating plastic modification technology, through the fiber, specialty lubricants, glass beads engineering plastics and so on self-lubricating reinforced modified so as to achieve a certain performance, then use the modified plastics processing by injection molding of plastic self-lubricating bearings, more professional global manufacturer of German IGUS and Chinese CSB company.
      Metal sliding bearings currently used most is the three-layer composite bearings, these bearings are generally carbon steel plate as the substrate, by sintering technology in the first sintered layer of spherical copper plate, then sintered on the copper layer of the the 0.03mm PTFE lubricant; wherein the intermediate layer of spherical copper main role is to enhance the bonding strength between steel and PTFE, of course, play a role in the work and lubricating Shihai; more professional global manufacturer in the United States of GGB, Japan OILES company and China's CSB company; the world in recent years are bearing manufacturing base also emerged a number of outstanding small and medium enterprises, large enterprises comprehensive strength, the SME segment to the direction of development, such as III and non-oil lubricated bearings specially developed valves stainless steel sliding bearings, sliding bearings developed specifically Triumph accessories mold industry, the development of injection molding machines You are willing bearings and other accessories, with the development of bearing industry, industry segments and more obvious, small enterprises have gradually narrowed the gap with the big companies. Through the above description is not difficult to see that the presence of plastic bearings and metal sliding bearing the following differences:
     1, plastic bearings are lubricated material overall, long life; and metal bearing surface of the lubricating layer is only 0.003mm of PTFE, when this thin layer of friction after it declared the end of life; 2, plastic bearings the use will not occur rusting and corrosion, rust and metal bearings can not be used in chemical liquid; 3, plastic bearings metal mass ratio of light, which is more suitable for modern lightweight design trends; 4, plastic bearings the manufacturing cost is lower than the metal; plastic bearings used in injection molding processing is more suitable for mass production; 5, plastic bearing no noise during operation, has a shock-absorbing function; As the plastic compared with metal bearings plain bearings exist numerous advantages of plastic bearings production is growing, plastic bearings use the occasion has also been extended, from fitness equipment to office equipment and automotive industries, etc. are made of plastic bearings, on the highway moving car no plastic bearing. Plastic bearings market prospects is unlimited!
