The self-lubrificating bushing of the series ADU is a 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 . The ADU bushings are widely applied in various sliding articles of different kind of machines such as textile machines, Tobacco machines, Hydraulic vehicles, automobiles, agriculture and forests machines and so on.
