Abstract
Provided is a lubricant composition that, even when the viscosity thereof has decreased, can suppress abrasion of bearings, etc. and scoring of gear tooth surfaces, etc. A lubricant composition that contains a lubricant base oil and a sulfur-based extreme pressure agent. The lubricant composition is characterized in that the amount of active sulfur in the extreme pressure agent is 5-30 mass % and in that the extreme pressure agent content of the lubricant composition is 5-15 mass % with respect to the mass of the whole composition.
Claims20
A lubricant composition comprising a lubricant base oil and a sulfur-based extreme pressure agent, wherein the amount of active sulfur in the extreme pressure agent is from 5% to 30% by weight, and the content of the extreme pressure agent in the composition is from 5% to 15% by weight based on the total weight of the lubricant composition.
