This report mainly discusses on characteristics of the iron-copper bearings by studying on several following problems; a) Effects of velocity and pressure of friction on the bearing performance. b) Effects of copper-content of the compacts on the bearing performance. c) A comparison on the bearing performance between the iron-copper bearings and a sintered porous bronze bearing.<BR>The results obtained are as follows ; 1) It should be of advantages to use the iron-copper bearings for more heavy duty applications, because the matrix-metal of these bearings has a high toughness considerably against metal-flow on the shaft-sliding surface of bearing. 2) As compared with maximum permissible PV value between the iron-copper bearings and the bronze bearing, the formers are about 1.6-2.0 times higher than the latter having about 1000 kg/cm<SUP>2</SUP>. m/min. 3) And the best results are obtained when the iron-copper bearing has a copper-content of about 25wt%o.
