PROBLEM TO BE SOLVED: To provide a rolling bearing which can prevent the generation of noise while effectively preventing exfoliation on a bearing rolling face caused by hydrogen brittleness.SOLUTION: A rolling bearing 1 comprises an inner ring 2, an outer ring 3, a plurality of rolling bodies 4 interposed between the inner ring and the outer ring, and a cage 5 for holding the rolling bodies 4. A grease compound is sealed into a periphery of the rolling bodies 4, the grease compound includes base oil, a thickener, and at least one additive which is selected from alkanol amine and molybdate, the base oil is poly-α-olefin oil whose dynamic viscosity at 40°C is 30 to 70 mm/s, the thickener is an aliphatic alicyclic diurea compound, and the additive is contained at 0.1 to 10 pts.wt. with respect to 100 pts.wt. of a total amount of the base oil and the thickener.SELECTED DRAWING: Figure 1 |
