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. Lemak diri. Lapisan Campuran PTFE 0.01-0.03mm. Setelah proses penggulungan selesai, campuran PTFE diisi di persimpangan lapisan gangsa. Dalam operasi normal, Sebilangan campuran PTFE pada lapisan atas akan dikeluarkan dan dipindahkan di permukaan kawin, membentuk sebuah filem pelincir secara fizikal, yang akan mengurangkan coction. dan melindungi batang kawin.
2. Lapisan Gangsa Berliang; Lapisan memberikan kekuatan ikatan Self-Lub. Lapisan.
3. Lapisan Keluli Lapisan memberikan kekonduksian beban & haba
4. Lapisan tembaga / Timah
