Castrol Molub-AlloyTM 777 ES greases are designed for very heavy-duty service in adverse environments. They are
blended and compounded to withstand the heavy- and shock-loading commonly found in the steel/primary
metals, construction, mining and forest products industries.
Molub-Alloy 777 ES greases are made using a blend of high-quality petroleum oils, polymers and a proprietary blend
of Molub-Alloy lubricating solids. These lubricating solids work synergistically with chemical anti-wear and extreme
pressure (EP) additives to help reduce contact temperatures and wear while providing the ultimate in extreme pressure
and shock load anti-weld protection. This blend—together with a shear stable thickening system—provides a uniquely
effective seal against loss of grease or contamination from the atmosphere, even where mechanical seals may be
damaged. Rust and oxidation inhibiting characteristics are maximized to afford effective rust protection and long life of
Molub-Alloy 777 ES are multi-purpose greases that operate effectively in plain/journal and anti-friction bearings.
They exhibit excellent adhesive and cohesive characteristics and are highly resistant to mechanical shearing.
Typical applications include ball and roller bearings, bushings, slides, screws, and general lubrication where loads may
be heavy and speeds low.
Industries most commonly requiring the heavy-duty, all-weather capabilities of Molub-Alloy 777 ES greases include
steel, mining, logging, chemical, and construction.
Molub-Alloy 777 ES 1 and 2 are Bucyrus-certified greases (with lubricating solids <5% by weight and <10 µm max
