摘要:
A lubricant for an oil retaining bearing containing 1 to 100% by mass of an ionic liquid. The lubricant has a low vapor pressure, low flammability, excellent heat resistance and ability to suppress the emanation of low volatile components and decomposed gases during use, or a lubricant for an oil retaining bearing which has antistatic property and is capable of grounding the static electricity generated by flow charging of the lubricant.
摘要:
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.
