Research of manufacturing of self-lubricating Cu-1 O%Sn alloy bearing component was carried out. The rllWmaterials for manufacturing bearing component were pure Cu metal powder, pure Sn metal powder, and addition ofmaterial1orporosity forming. The manufacturing of bearing component was through compacts and sintering treatments. To investigllteinfluence of the porosity distribution in bearing component, addition of material for porosity forming was varied from 2% to20%. Experiment result has shown that alloying process proceed during sintering treatment at temperature 830 .C. Tneformation of Cu-1 O%Sn alloy is caused diffusion mechanism of atomic liquid of Sn to the grain Cu metal powders. Tneformation of porosity mechanism is caused vaporizations processing of porosity forming material during sintering. Examinati mof oil absorption for specimens, increasing of addition of porosity forming material was followed decreasing of density a ldincreasing of oil absorption content, and material for porosity forming content is 4%, results self-lubricating bearing compornntwith density value 5. I 7gicmJ and oil content 27.97%. This associates to ASTM standard designation B 438-84.Key words: Bronze, bearing component, copper powder, tin powder.
