Part Name:SF-1F flanged bushings
Material: Steel backing+bronze powder+PTFE
Appearance:Tin plated or Copper plated SF1F 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. SF1F 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
