Galaxo Grease XG-279
Discription: Galaxo Grease XG-279 is a high Temperature grease, based on a blend of poly-alpha-olefin and mineral oil thickened with a lithium complex soap. It is fortified with anti-corrosion, antioxidant and anti-wear additives.
Application:
Galaxo Grease XG-279 is a high performance grease designed to lubricate bearings, pins and sliding parts in military automotive equipment (trucks, tanks, artillery guns, etc…). It is often referred as General Artillery Grease (GAA). It exhibits strong anti-corrosion and anti-wear properties to protect the lubricated
parts for extended period of time without re-greasing.Galaxo Grease XG-279 resists very well to water wash-out – the primary cause of bearing failures of wheel bearings.
The high-melting lithium complex thickener also enables Galaxo Grease XG-279 to withstand high temperature without melting or softening.
