Abstract: A grease composition comprises a base oil and an aluminium complex soap thickener, with graphite, molybdenum di-sulphide, calcium carbonate and bismuth sulphide all included as additives. The composition exhibits advantageous load, wear and friction performance, especially in extreme pressure environments, and is particularly suitable for use on open gears.
