The lubricant composition of this invention comprises a base oil and an additive, which is at least one selected from the group consisting of an organic sulfonate, a carboxylate, a thiocarbamate and a thiophosphoric acid ester salt. The lubricant composition can effectively suppress hydrogen embrittlement-caused flaking of an element, such as a rolling bearing, a sliding bearing, a gear, a ball thread, a linear guide, a linear bearing, a cam and various joints in a high concentration hydrogen environment. The invention provides also a rolling bearing, a sliding bearing, a gear, a ball thread, a linear guide, a linear bearing, a cam and various joints using the lubricant composition.
本发明的润滑剂组合物由基础油和添加剂组成,添加剂至少选自有机磺酸盐、羧酸盐、硫代氨基甲酸酯和硫代磷酸酯盐组成的组。该润滑剂组合物能有效抑制高浓度氢环境中因氢脆引起的元件剥落,如滚动轴承、滑动轴承、齿轮、球螺纹、直线导轨、直线轴承、凸轮和各种接头。本发明还提供了使用该润滑剂组合物的滚动轴承、滑动轴承、齿轮、球螺纹、直线导轨、直线轴承、凸轮和各种接头。
