    摘要： On an inner peripheral surface of a bearing hole into which a shaft is inserted, concave oil supply surfaces arranged dispersively like separated islands and a sliding surface continuous around the oil supply surfaces to hold an outer peripheral surface of the shaft are formed: a maximum height difference between the sliding surface and the oil supply surfaces is not less than 0.01% and not more than 0.5% of an inner diameter Di of the sliding surface; a surface aperture area ratio of pores at the sliding surface is not more than 10%; a surface aperture area ratio of pores at the oil supply surfaces is more than 10% and less than 40%; and an area of each of the oil supply surfaces is not less than 0.03 mm2 and not more than 0.2×Di2 (mm2).

    摘要： A Cu-based sintered sliding member that can be used under high-load conditions. The sliding member is age-hardened, including 5 to 30 mass % Ni, 5 to 20 mass % Sn, 0.1 to 1.2 mass % P, and the rest including Cu and unavoidable impurities. In the sliding member, an alloy phase containing higher concentrations of Ni, P and Sn than their average concentrations in the whole part of the sliding member, is allowed to be present in a grain boundary of a metallic texture, thereby achieving excellent wear resistance. Hence, without needing expensive hard particles, there can be obtained, at low cost, a Cu-based sintered sliding member usable under high-load conditions. Even more excellent wear resistance is achieved by containing 0.3 to 10 mass % of at least one solid lubricant selected from among graphite, graphite fluoride, molybdenum disulfide, tungsten disulfide, boron nitride, calcium fluoride, talc and magnesium silicate mineral powders.

    摘要： A sintered bearing has a structure in which Ni—P alloy particles having an average diameter of 10 to 100 μm are dispersed in an amount of 1 to 20% by mass in a Cu-based sintered alloy base, a Fe—Cu-based sintered alloy base or a Cu—Ni-based sintered alloy base. The Ni—P alloy particles are derived from a raw material powder comprising 1 to 12% by mass of P; and a remainder composed of Ni and inevitable impurities. The Cu-based sintered alloy base contains no less than 40% by mass of Cu. The Fe—Cu-based sintered alloy base contains no more than 50% by mass of Fe. The Cu—Ni-based sintered alloy base contains 20 to 40% by mass of Ni and 0.1 to 1.0% by mass of P; or contains 10 to 25% by mass of Ni, 10 to 25% by mass of Zn and 0.1 to 1.0% by mass of P.
