It occurs when the work is bearing sliding friction; rolling friction depends mainly on the size of the manufacturing precision; sliding 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 bearings and metal sliding 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.
Metal sliding bearings bearing the most used 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 layer on the copper layer the more of 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, in the work, also play a role in bearing and lubrication.
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 is only 0.003mm lubricating layer of PTFE, when this thin after friction layer also declared the end of life; 2, plastic bearings rusting does not occur and resistant to corrosion, and rust metal bearings can not be used in chemical liquid; 3, plastic bearings metal mass ratio light, which is more suitable for modern lightweight design trends; 4, plastic bearings manufacturing cost is lower than the metal; plastic bearings used in injection molding processing is more suitable for mass production; 5, plastic bearing no running noise, vibration absorber has a certain function; As the plastic compared with metal bearings plain bearings there are many 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. using a plastic bearing, on the highway moving car no plastic bearings. Plastic bearings market prospects is unlimited!
