Self lubrificating bushes in PFTE without lead

Is wall wrapped bearings made of triple layer composites material which consists of a steelbacking, a sintered porous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer. It is of low friction coefficient, anti-wear, anti-corrosion and can be used without oil, or only a trace of oil is needed. Moreover, it is of low cost, low vibration and lownoise, compact and light. MU as widely applied. In various sliding articles of different kind of machines such as texte machines, Tobacco machines, Hydraulic vehicles, automobiles, agriculture and forests machines and soon.
