PM Sintered Joint Bushing


Mechanical properties


Using the iron and copper alloys as the main raw materials and applying PM sintering craft

Solid lubricants like graphite inside the material, treated with oil impregnation to guarantee the lower wear rate even without oil

Owing higher load and superior wear resistance conparaed to traditional PM bushings



Hydraulic cylinders, construction machines, loaders, crane and agricultural machines.
