Abstract

The present invention aims to improve the extreme-pressure properties and compatibility with seals of lubricating grease compositions used at lubrication points where extreme-pressure properties and seal- resistance properties at high loads are required in various kinds of machinery. To this end the present invention provides a lubricating grease composition wherein from 0.1 to 3% by weight of a molybdenum dialkyl dithiocarbamate, from 0.1 to 3% by weight of benzothiazole compounds and from 0.1 to 3% by weight of calcium sulphonates are incorporated in a grease in which a thickening agent is blended in the base oil.
