EU Kort beskrivelse

EU-trelags vedligeholdelsesfri bøsning har en base af lavere kulstofstål, hvorpå et porøst bronzelag er sintret. PTFE-blandinger er imprægneret i krydset mellem dette bronzelag efter afsluttet rulleproces. Eu har gode fysiske og mekaniske egenskaber, har også bestemt kemiske egenskaber. Den er velegnet til roterende, oscillerende bevægelser med ydeevne af selvsub. Anti-slid, lavere firction, lavere støj.

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
