摘要
An object of the present invention provides a high wear resistance and the CO 2 refrigerant compressor bearings and, respectively, using compressors such a bearing, air conditioner, refrigerator, and hot water supply with the use of the bearing material having a load bearing plastic and the life of the high reliability and long-term to. CO 2 refrigerant compressor bearing according to the present invention and a compressor, the air conditioner using such a bearing group, refrigerator and hot water supply comprises the said bearing cylindrical member and a graphite-containing carbonaceous material in the cylindrical member is tin or IB group or It characterized by having a hole in which the alloy is impregnated based on the metal or the metal of the selected one type from group VIII, except for iron, and includes a carbonaceous material by each of the bearing containing 20 to 50 weight percent heukyeonreul and corresponding Shore hardness of the member is in the range of between 65 to 120, the range between the compression strength is from 200 to 500 MPa of the corresponding member, and a porosity of 0.05 to a range of 2.00 percent by volume of the corresponding member, the metal or alloy contained in the response member this is characterized in that it satisfies at least one vanadium or at least one of the conditions to be a titanium-containing, or both in a proportion of up to 0.2 weight percent. ; Based carbonaceous material, shore hardness, porosity, near-net shape, scroll
