    1. Detailed information

    SF-1PI bearing is consists of a steel backing,a sintered porous bronze particles interlayer and coated with polyimide(P).Polyimide is a high mechanical strength organic polymer material.withhighalermating oad capacity,good fatigue resistance,not bibulous and corrosion-resistant,so it can be use in lots situation like tensioning wheel, and long time used in 300 C for it good thermal stability.
