    摘要: A rolling or sliding part is produced from a blank of steel material subjected to a heat treatment including carburization and thereby made to contain a spheroidal carbide precipitated and dispersed in a carburized layer matrix. The particle-to-particle distance of the spheroidal carbide is up to 15 &mgr;m in terms of the distance between the most proximate particles. The rolling or sliding part is suitable as antifriction bearing components, such bearing rings and rolling bodies, or as sliding bearing components, for use in soiled oil containing extraneous matter. The antifriction bearing comprising this part serves a lengthened rolling life in soiled oil and clean oil, and the sliding bearing incorporating the part is also given an extended life.
