EXB POM lined Copper base Bearing

EU tri-layer maintanence-free bushing (EXB POM lined Copper 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 rction, lower noise.

1. Self-lub. Layer POM 0.3-0.5mm. After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which 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.
