| description | To provide a lubricant composition which has a lower viscosity than conventional ones and is excellent in metal fatigue life, wear resistance, and electrical insulation properties.SOLUTION: The lubricant composition contains: (A) a lubricant base oil; and (B) a polydiene having a number average molecular weight of 500-3,000 and having a functional group on at least one terminal in an amount of 0.6-4.0 mass% based on the mass of the whole lubricant composition. The lubricant composition does not contain a viscosity index improver and has a kinematic viscosity at 100°C of 1 mm/s or more and less than 5 mm/s.SELECTED DRAWING: None
【課題】従来よりもさらに低粘度化した潤滑油組成物であり、且つ、金属疲労寿命、耐摩耗性、及び電気絶縁性に優れる潤滑油組成物を提供することを目的とする。【解決手段】（Ａ）潤滑油基油、及び、（Ｂ）数平均分子量５００〜３０００を有し、少なくとも１の末端に官能基を有するポリジエンを潤滑油組成物全体の質量に対して０．６〜４．０質量％となる量で含み、粘度指数向上剤を含まず、１００℃での動粘度１〜５ｍｍ２／ｓ未満を有することを特徴とする潤滑油組成物。【選択図】なし |
