INQUIRY

PE-B bronze Backing PTFE Composite bushing

is wrapped by steel backing, Sintering bronze inter layer and PTFE(Teflon) 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 DU SF-1 PTFE Composite Bronze Bushing

PTFE oilless dry bearing bushing is in carbon steel backing with sintered bronze intermediate layer, then PTFE (teflon) composite inner coated.PE model code means carbon steel in cylinder type bushing
