SF-1 is a kind of thin wall wrapped bearings made of triple layer composites material which consists of a steel backing, a sintered porous bronze particles interlayer and calender 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. More over, it isof low cost, low vibration and low noise, compact and light, and can form a transfer film of PTFE which protects the mating surface from scoring.

SF-1 is widely applied in various sliding articles of different kind of machines such as printing machines, textile machines, tobacco machines, gymnastic machines, hydraulic vehicles, automobiles, motorcycles, agriculture and forests machines and so on..
