Castrol Molub-AlloyTM 777-2 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 777-2 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 the grease.
Advantages:
Excellent friction reduction characteristics due to Molub-Alloy solid lubricants – easier start-up, reduced heat, and reduced energy, leading to longer bearing life.
Excellent mechanical stability – grease keeps its consistency in-service, ensuring long term protection.
Easily pumpable in central lubrication systems.
Superior adhesion – continuous lubrication and reduced consumption as the film stays between lubricated surfaces.
Exceptional water resistance – coating film stays on the surface even in the presence of water.
Resistant to copper and steel corrosion – extends bearing life and performance.
Excellent EP and anti-wear properties – protects equipment against extreme/shock loading and helps minimize bearing components wear and hence extends equipment life.
Compounded – optimum protection and long life to seals, as well as forming a protective barrier in damaged seals.
Applications: Molob-Alloy 777-2 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 777-2 ES greases include steel, mining, logging, chemical, and construction.
Molub-Alloy 777-2 ES is Bucyrus-certified greases (with lubricating solids <5% by weight and <10µm max particle size).
