PURPOSE:To obtain a high strength copper-base sintered bearing having a high oil content and showing superior performance n a high load region by adding a specified amount of Fe to a Cu-Sn-P material. CONSTITUTION:A high strength copper-base sintered bearing material having a high oil content is composed of 4-11wt% Sn, 0.2-1.0% P, 5-20% Fe and the balance Cu with inevitable impurities. To the composition may be added 1-10% of >=1 kind of lubricating components such as graphite, molybdenum disulfide or Pb. By the composition, hard Fe particles in a bearing prevent the plastic flow of the sliding surface, and superior bearing performance is shown in a high load region. |
