At present the use of the bearings can be divided into general and the Rolling sliding bearing; rolling bearings and sliding bearing the name of principle can be adopted to distinguish, when the Rolling friction is rolling friction, and sliding bearing when the work is sliding; Rolling friction mainly depend on the size and manufacture of precision bearings and sliding friction bearings depends primarily on the size of the sliding surface material. Bearing in general face are all self-lubricating function in accordance with the sliding bearing materials into non-metallic sliding bearings and metal sliding bearing. At present, non-metallic sliding bearing mainly to plastic bearings, plastic bearings are generally used relatively good performance of engineering plastics made; comparison of professional engineering plastics manufacturers generally have the self-lubricating modification technology, through fiber, special lubricants, glass Beads of engineering plastics, etc. to enhance the self-lubricating modified so that it reached a certain performance, and then modified by plastic injection molding processed into self-lubricating plastic bearings, the world's comparison of professional manufacturers to Germany and China, the CSB IGUS公司. Metal Bearing is the most current three-tier composite bearings, bearings in general are such a carbon steel plate for the substrate, through sintering technology in the first sintering plate on a spherical copper powder and then a layer of copper powder layer on the sintering 0.03mm PTFE the lubricant of which the middle layer of spherical copper plate main role is to enhance the Deep Groove Ball Bearing Self-aligning Ball Bearing Angular Contact Ball Bearing integration between PTFE and strength, of course, the work also plays a certain bearing and lubrication; current global comparison of professional manufacturers to the U.S. The GGB company, Japan's OILES company and China's CSB companies can easily see through the above description, plastic and metal bearings sliding bearing exist following differences: 1, plastic bearings as a whole are lubricating materials, long life and the metal sliding bearing Lubrication is only the surface layer of 0.003 mm PTFE, when the thin layer of friction End also declared the end of life; 2, the use of plastic bearings will not rust and corrosion resistance phenomenon, and the rusting metal bearings can not be easy For the chemical solution, 3, plastic, metal bearings than the quality of light, more suitable for modern light-design trends, 4, plastic bearings manufacturing costs lower than metal, plastic bearings used in injection molding is more suitable for processing from the Volume production; 5, plastic bearings in operation without any noise, vibration absorption of certain functions because of plastic than metal bearings sliding bearing the existence of numerous advantages, the output of plastic bearings are growing, the use of plastic bearing occasions are also constantly The extension, from fitness equipment to office equipment and automotive industries, etc. are used plastic bearings, in the car on the highway without the use of plastic bearings. Plastic Bearing broad market prospects unlimited!
