Abstract
The Cu-based sintered alloy bearing of the present invention is made of a Cu-based sintered alloy with a composition consisting of, by weight, Ni: 10 to 25%, Zn: 10 to 25%, P: 0.1 to 0.9%, C: 0 to 5%, molybdenum disulfide: 0.5 to 5%, and Cu and inevitable impurities as the balance. The Cu-based sintered alloy has a texture from a Cu—P compound, free graphite, and molybdenum disulfide being dispersed in a base material made of a solid solution phase of a Cu—Ni—Zn alloy, and a porosity is within a range of 5 to 25%.
