    摘要: PROBLEM TO BE SOLVED: To obtain a rustproof grease composition exhibiting excellent anti-corrosive properties even without using a nitrite and a bearing filled with the rust-proof grease composition.
    SOLUTION: The grease composition is obtained by mixing a base oil with a thickening agent and a rustproof component. The rustproof component comprises a polybasic acid metal salt, a polyhydric alcohol containing a partially blocked hydroxy group and at least one compound selected from an organic sulfonic acid salt and a fatty acid ester as essential components. The amounts of the rustproof components are 0.1-10 parts wt. based on the total of the base oil and the thickening agent, respectively. The base oil contains at least one selected from a synergistic hydrocarbon oil and an ether oil. The thickening agent is a urea-based thickening agent and the amount of the thickening agent is 5-30 parts wt. based on the total of the base oil and the thickening agent. The grease-filled bearing has a sliding part filled with the rustproof grease composition.
