摘要

A grease composition sealed in a rolling contact bearing contains a base oil in the form of a mixture of an alkyldiphenylether oil and a poly-(alpha)-olefin oil. The weight ratio of the former to the latter is between 20:80 and 80:20. 5-40% by weight of thickening agent which is at least one of an aromatic diurea compound and an aromatic urea-urethane compound is added to the base oil. Further, a passivation oxidizing agent and an organic sulfonate are added.
