An industrial gear lubricating oil composition used for resisting micro-pitting comprises (A) at least one deeply refined mineral oil or synthetic oil, or any combination of above components, (B) at least one additive for resisting micro-pitting; (C) at least one anti-wear additive; (D) at least one metallic passivator; and (E) at least one antioxidant. The lubricating oil composition has excellent high and low temperature performances to meet the viscosity grade requirements of the 68, 100, 150, 220, 320, 460 and 680 industrial gear oil, has excellent micro-pitting resistance performance, anti-wear performance and anti-oxidation performance, and has passed FVA 54 micro-pitting resistance test, FAG FE-58 bearing wear test and SKF EMCOR bearing corrosion test. It is applicable for many large industrial transmission machineries and some automotive transmission machineries, especially applicable for gear transmission system of wind turbine generator. |
