Part Name:SF-1 BUSH Material: Steel backing+bronze powder+PTFE Appearance:Tin plated or Copper plated
SF-1 is wall wrapped bearing made of triple layer composites material which consists of a steel backing,a sintered porous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer.It is of low friction cofeeicient and has good performance in anti-wear,anti-corrosion and can be used without oil lubrication.It is of low cost, compact, anti shaft seizing and low noise. SF-1 is widely applied in various sliding position of different kind of machines,such as textile machines,lift,tobacoo machines,fitness equipment ,hydraulic vechicles,antomobiles,agriculture and forest machinese and so on. Load capacity:140N/mm2 Friction coef(u):0.04~0.20 Temperature:-195~+280°C Speed limit:5m/s PV limit(dry):3.6N/ mm2.m/sPV limit(oil):50N mm2.m/s
