This is the material observe ROSH . We also can provide the samples according to the drawings within 15 days.

SF1W is wall wrapped bearing made of triple layer composites without lead material which consists of a steel backing,a sintered porous bronze particles interlayer and calendared with PTFE as surface layer,It is of low friction cofeeicient,anti-wear,anti-corrosion and can be used without oil,or only a trace of oil os needed.moreover,it is of low cost,low vibration and low noise,compact and light.
