EU Struktur
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
EU Structure
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
