摘要：
The present invention provides a lubricant composition which can be used as a lubricant for a rolling component, the composition capable of maintaining enhanced lubrication performance over a long period of time even under high temperature conditions such as temperatures of 180°C or higher, and a rolling bearing including the lubricant composition sealed therein. A lubricant composition-sealed bearing 1 includes a lubricant composition 7 that is sealed in the peripheries of the rolling bodies 4. The lubricant composition 7 contains a base oil and an antioxidant. The base oil is an oil mixture of an alkyl diphenyl ether oil and at least one oil selected from a poly- α -olefin oil and an ester oil, and contains the alkyl diphenyl ether oil in an amount of 50% or more by weight of the total base oil. The antioxidant is 2,2,4-trimethyl-1,2-dihydroquinoline or a polymer thereof, and is contained in an amount of 0.1% to 10% by weight of the total lubricant composition.
摘要（中）：
本发明提供一种润滑剂组合物，其可以用作滚动部件的润滑剂，该组合物即使在高温条件如180℃或更高的温度条件下也能长时间保持增强的润滑性能， 包括密封在其中的润滑剂组合物。 润滑剂组合物密封轴承1包括密封在滚动体4周围的润滑剂组合物7.润滑剂组合物7包含基础油和抗氧化剂。 所述基础油是烷基二苯醚油与至少一种选自聚-α-烯烃油和酯油的油的油混合物，并且所述烷基二苯醚油的含量为50重量％或更多 总基础油。 抗氧化剂是2,2,4-三甲基-1,2-二氢喹啉或其聚合物，其含量为全部润滑剂组合物的0.1重量％至10重量％。
