EU PTFE lined Steel base Bearing description

EU tri-layer maintanence-free bushing (EU PTFE lined Steel base Bearing) have a base of lower carbon steel, onto which a porous bronze layer is sintered. PTFE mixtures are impregnated into the intersice of this bronze layer after rolling process completed. Eu has good physical & mechanical properties, also has certainly chemical properties. It is suitable for rotary, oscillating movement with performance of self-lub. Anti-wear, lower firction, lower noise.

1. Selbstlubber. Schicht PTFE Mëschung 0.01-0.03mm. Nom rullende Prozess ofgeschloss, PTFE Mëschunge ginn am Schnëtt vu Bronzeschicht gefëllt. Ënner normaler Operatioun gëtt en Deel vun der PTFE Mëschung op der ieweschter Schicht entfernt an iwwerdroe mat der Uewerfläch, bild e kierperlech schmierende Film, deen d'Firction Coe reduzéiert. a schützt de Paartwelle.
2. Porous Bronzeschicht; D'Schicht bitt gebonne Kraaft vu Selbstlub. Schicht.
3. Steel Backing D'Schicht liefert Wärmeleitfäegkeet
4. Kupfer / Zinnschicht

1. Self-lub. Layer PTFE Mixture 0.01-0.03mm. After rolling process completed, PTFE mixtures are filled in intersice of bronze layer. Under normal operation, Part of PTFE mixture on top layer will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2. Porous Bronze layer; The layer provides bonded strength of Self-Lub. Layer.
3. Steel Backing The layer provides load thermal conductivity
4. Copper / Tin layer
