SINTERED METALLIC MATERIAL, OIL-RETAINING BEARING CONSTITUTED OF THE METALLIC MATERIAL, AND FLUID BEARING APPARATUS

摘要

A sintered metallic material improved in sliding properties and wearing resistance in sliding on a sliding mating material to be supported. A mixed metal powder comprising 5-94.3 wt.% copper powder, 5-94.3 wt.% SUS powder, 0.2-10 wt.% tin powder, and 0.5-2.5 wt.% graphite is compacted and then sintered to form a bearing sleeve (8).
