A rolling bearing is filled with a grease composition comprising a fluorine-based base oil and a fluorine-based thickening fluorine-based grease, a non-fluorine-base non-fluorine-base grease and a non-fluorine-based non-fluorine-based grease, and a dispersant-serving grease contains. The non-fluorine-based thickener comprises at least one of aliphatic-aromatic urea, alicyclic-aliphatic urea, and aliphatic urea. The dispersing agent comprises at least one of polycarboxylic acid metal salt, fluorine-containing group / lipophilic group-containing oligomer, diamide of fluorinated ether and metal salt of organic acids. |
