PE-F Flanged Oilless Bush
PE-F PTFE coated steel backing flanged oiIless dry bearing bushing
is wrapped by steel backing, Sinter bronze inter layer and PTFE composite anti-wear inner surface. Also it is name SF-1 bushing in China and DU,DP4,PAP P10 overseas. It is wildly used in hydraulic gear pumps, oil cylinder, oil Damping bushes and piston rings for automobiles and motorcycles and textile, food-stuff machines, etc.
PE-F Flanged ptfe oilless dry bearing bushing is in carbon steel backing with sintered bronze intermediate layer, then PTFE (teflon) composite inner coated.PE-F model code means carbon steel in flanged type bushing. FEB-F is in bronze backing,FESS-F is in stainless steel backing.
