    Abstract: Disclosed is a lubricant composition comprising a base oil which contains 50% by mass or more of at least one of an α-olefin oligomer and a hydrogenated product of an α-olefin oligomer and in which the kinematic viscosity and the flash point satisfy the following relational equation (I): Flash point (° C.)≧49×ln γ+90  (I) [provided that γ is a kinematic viscosity at 40° C.].The lubricant composition contains a base oil which has little effect on a resin or elastomer because it is a nonpolar compound, in addition to having an extremely small amount of evaporation and a high flash point despite a low viscosity, and is suitable for various applications, in particular, as bearing oils.

    Abstract: The present invention provides a process for producing a saturated aliphatic hydrocarbon prepared using an α-olefin as a raw material and represented by the general formula (1), including the steps of: (I) producing a vinylidene olefin by dimerizing the α-olefin in the presence of a metallocene complex catalyst; (II) further dimerizing the vinylidene olefin in the presence of an acid catalyst; and (III) hydrogenating the obtained dimer. Further, there are provided a lubricant composition containing the saturated aliphatic hydrocarbon compound produced by the above process, a bearing oil consisting of the lubricant composition, and making use of the same, a bearing and gyral equipment. The saturated aliphatic hydrocarbon compounds produced by the process of the present invention have low-temperature fluidity, exhibiting low evaporativity, and excellent in thermal stability and oxidation stability. Thus, the saturated aliphatic hydrocarbon compounds are suitable for use as, for example, a base oil of lubricant composition for hydraulic pressure, turbine, working machine, bearing, gear, metal-working, etc.
