Grease composition with improved extreme pressure and antiwear properties

摘要

Disclosed is a grease composition comprising a major amount of a lubricating oil base vehicle, a lithium gellant in an amount sufficient to thicken the base vehicle to grease consistency, an alkali-metal borate in an amount sufficient to impart extreme-pressure properties to the grease and from 0.1 to 10.0 mass percent of antimony dithiocarbamate.
