In article we presented results of investigations of self-lubricating porous bearing impregnated by greases. These bushes were worked on special research stand under conditions of different load and rubbing speed, but constant p´v value. We also performed initial durability test (1000 hours) for chosen porous bearings. The linear wear, lubricant loss, change of hardness and surface roughness of bearings were also measured.
