摘要： A rolling bearing, for use in household appliances, having a high degree of quietness, an excellent durability at high temperatures and rotational speeds, a low torque, and excellent fretting property; and a lubricant composition which can be sealed into the rolling bearing. The lubricant composition includes a base oil and a thickening agent. The base oil is a mixed oil having the following characteristics of (a) to (c): (a) The base oil consists essentially of a synthetic hydrocarbon oil and an ester oil; (b) A kinematic viscosity of the mixed oil at 40° C. is 40 to 70 mm2/second; (c) A mixing weight ratio between the ester oil of the mixed oil and the synthetic hydrocarbon oil thereof is 30:70 to 70:30. The thickening agent comprises a diurea compound shown by a formula (1): where R1 and R3 are a straight-chain alkyl groups having 9 to 22 carbon atoms respectively, and R2 is an aromatic hydrocarbon group having 6 to 15 carbon atoms. The lubricant composition is sealed into the rolling bearing.

摘要： There is provided a grease composition, in which a grease film on the surface of the applied part is made thicker compared with conventional grease compositions, this thickness is maintained for a long period of time, and as a result, a longer service life against seizure compared with conventional grease compositions is assured. The grease composition comprises a base oil and a thickener, wherein the thickener is a diurea compound obtained by allowing an amine mixture comprising alkylphenylamine, an alkyl group of which has 8 to 16 carbon atoms, and cyclohexylamine, to react with a diisocyanate compound, and an amount of cyclohexylamine in the total amount of the alkylphenylamine and cyclohexylamine is from 91 to 99% by mole.
摘要翻译：提供了一种润滑脂组合物，其中与常规润滑脂组合物相比，使涂敷部件表面上的润滑脂膜变得更厚，该厚度长时间保持，结果使得使用寿命更长与常规润滑脂组合物相比确保。润滑脂组合物包括基油和增稠剂，其中增稠剂是通过使包含烷基苯基胺（其烷基具有8至16个碳原子）和环己胺与胺化合物反应的胺混合物与二异氰酸酯化合物反应而获得的二脲化合物，以及烷基苯胺和环己胺的总量中的环己胺的量为91〜99摩尔％。
