摘要：The properties of a lubricating oil are utilized to avoid excessive quality in termsof the circularity of roller members while reducing the noise from a radial roller bearingalone during rotation and thereby reducing the noise from a rotary machine. A radialroller bearing includes an outer ring member (30A), a plurality of roller members (30B),and a retainer, and a lubricating oil (O) is supplied between the outer ring member (30A)or a rotating shaft and the roller members (30B). The circularity (”R) of the rollermembers (30B) in a cross section perpendicular to a centerline (CL) thereof is set to belower than or equal to the minimum oil film thickness (h min ) of an oil film formed by thelubricating oil (O).
