    Abstract: Grease compositions comprising (1) as a base fluid a polyol aliphatic ester and (2) as a thickener finely divided sodium montmorillonite clay. The clay may be used as the sole thickener or it may be used in combination with a finely divided fluorinated ethylenepropylene copolymer. Also, molybdenum disulfide or antimony dialkyldithiocarbamate may be added to the compositions. The compositions have both good wear characteristics and good extreme pressure characteristics at temperatures in the -65* F. to 350* F. range. The grease compositions are useful in heavily loaded airframe bearings, screw jack actuators, journal bearings, and in other applications where there is sliding, rolling, oscillating, or other forms of motion where wear and extreme pressure are factors.
