These bearings are self-lubricated and can be used in places where no lubricating is possible. In this study, tribological and mechanical properties of copper based CuSn10, ferrous based Fe-graphite and copper+ferrous based CuSnFe-graphite bearings manufactured by powder metallurgy method have been determined and compared. Wear tests were carried out at 20 N load and 1500 rev min-1 every 30 min for 2.5 h using radial journal bearing wear test rig. Hardness, tensile, compressive, bending and radial fracture mechanical tests of these bearing materials were carried out. As a result, tribological and mechanical properties improved in CuSnFe-C bearings. © 2011 Institute of Materials, Minerals and Mining.EnglishBending testsCopper smeltingFractureGraphiteIronJournal bearingsPowder metallurgySelf lubricating bearingsSinteringTribologyBearing materialsBearing wearCopper-basedPowder materialRadial fracturesSinter bearingTribological performanceWear testMechanical propertiesArticle10.1179/003258909X12553422176880
