GREASE COMPOSITION AND ROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a grease composition excellent in burning resistance without deteriorating stirring resistance in a rolling device, and to provide a rolling device at whose prescribed site the grease composition intervenes.SOLUTION: A grease composition comprising a base oil and a thickener, is characterized in that the thickener is a diurea compound obtained by reacting an amine mixture comprising an alkyl phenyl amine (the carbon number of the alkyl group is 8-16) and cyclohexylamine with a diisocyanate compound; the content of the cyclohexylamine in the amine mixture is ≥80 mol% and <91 mol%; and worked penetration is 300-330; and a rolling device characterized in that the grease composition is sealed.
