    Abstract: A heat-resistant, high-speed, high-load rolling bearing for automotive accessories and electric part is provided which develops no abnormal flaking and is sufficiently long in life and superior in durability. It is a heat-resistant, high-speed, high-load rolling bearing in which is sealed a grease composition which comprises a base oil which is a mixture alkyldiphenyl ether oil and aromatic ester oil at the ratio (in weight) of 50:50 to 80:20, a diurea compound expressed by the following formula as a thickening agent, and 0.1 to 5 wt % of a passivating agent. 1 (wherein R2 is an aromatic hydrocarbon group having a carbon number of 6-15, R1 and R3 are an aromatic hydrocarbon groups having a carbon number of 6-12 or a cycloaliphatic hydrocarbon group having a carbon number of 6-20. R1 and R3 may be identical to or different from each other.)
