PROBLEM TO BE SOLVED: To provide a roller bearing with excellent preventive performance of grease leakage, heat resistance, rust and dispersive performance of hydrocarbon solvent even if it is the bearing treated by rust preventive oil using mineral oil as base oil, which can reduce the cost more than fluorine grease. SOLUTION: This is a roller bearing which consists of an inner ring 2 as well as an outer ring 3 which are arranged concentrically, two or more rolling movers 4 which are fit between this inner ring and outer ring, and the lubrication grease 5 sealed around these rolling movers. The lubrication grease 5 is made by grease B which makes perfluoro polyether oil be base oil and fluorine carbon resin particle be thickening agent and grease A which makes synthetic oil be base oil and urea compound be thickening agent.
