| description | The present invention provides a grease composition for a hub unit bearing for a vehicle, in which a base oil is a synthetic hydrocarbon oil having a kinematic viscosity at 40 DEG C of 25-50 mm2/s, a thickener is an alicyclic aliphatic diurea compound, and the amount of the base oil is less than or equal to the total mass of the composition, and the amount of the thickener is less than or equal to the total mass of the composition. The present invention is characterized by containing 0.1-5 mass% of a carboxylic acid-based rust inhibitor, 0.1-5 mass% of a carboxylate-based rust inhibitor, and 0.1-3 mass% of an amine salt of a fatty acid, respectively, and by having a mixing consistency of 220-270.
本发明提供一种车辆用轮毂单元轴承用润滑脂组合物，其中，基础油为40℃的运动粘度为25～50mm2/s的合成烃油，增稠剂为脂环式脂肪族二脲化合物，以组合物的总质量为基准，分别包含0.1～5质量％的羧酸系防锈剂、0.1～5质量％的羧酸盐系防锈剂以及0.1～3质量％的脂肪酸的胺盐，混合稠度为220～270。 |
