PROBLEM TO BE SOLVED: To provide a bearing material securing sufficient abrasion resistance in a compressor employing a material of a grade having a slight ferrite phase in the matrix of nodular graphite cast iron for a crankshaft or an alloy impregnated die eutectic graphite cast iron for the crankshaft and having a matrix formed of a ferrite matrix. SOLUTION: The compressor is formed to prevent the sticking of a crankshaft 8 made of nodular graphite cast iron or alloy impregnated die eutectic graphite cast iron and ferrite matrix of the crankshaft by being almost pearlitized through the suppression of the occurrence of a ferrite of a matrix structure in a bearing so as to secure abrasion resistance between the crankshaft 8 and a main bearing 9 and auxiliary bearing 10.
