EX tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer. EX has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.
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.
