Zusammenfassung: | Provided is a rolling bearing using a retainer, particularly a highly reliable retainer in which dimensional stability required for a retainer of an outer ring guide type, ductility required for a crown-type retainer, improvement in adhesion of grease with a poly-α-olefin oil or the like as a base oil, and deformation prevention at a high speed can be achieved. The rolling bearing includes at least an inner ring 1, an outer ring 3, a synthetic resin retainer 9, and a rolling element 7, in which the synthetic resin retainer 9 is formed of a polyamide resin composition including polyamide 410 and a reinforcing fiber material with a content of 0% by weight to 40% by weight. |
