Castrol MA 777-1 ES 180KG
Castrol Molub-Alloy™ 777 ES greases are designed for very heavy duty service in extreme environments, blended and compounded to withstand heavy and shock loading commonly found in the steel/primary metals, construction, mining and forest products industries. They are made using a blend of high quality petroleum oils, polymers and Molub-Alloy lubricating solids, which work synergistically with chemical anti-wear and extreme pressure (EP) additives to reduce contact temperatures and wear while providing outstanding protection under extreme pressure and shock load conditions; rust and oxidation inhibiting characteristics are maximised for effective rust protection and long grease life. Molub-Alloy 777 ES greases are multi-purpose greases that operate effectively in plain/journal and anti-friction bearings, exhibiting excellent adhesive and cohesive characteristics and high resistance to mechanical shearing. Typical applications include ball and roller bearings, bushings, slides, screws, and general lubrication where loads may be heavy and speeds low, across industries including steel, mining, logging, chemical, and construction. Molub-Alloy 777-1 ES and 777-2 ES meet the specification of Bucyrus International (CAT) and Komatsu greases (with lubricating solids <5% by weight and <10 µm max particle size).

KEY FEATURES
| •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 |
| •Excellent water resistance – coating film stays on the surface even in the presence of water |
| •Provides protection against copper and steel corrosion |
| •Excellent EP and anti-wear properties – protects equipment against extreme/shock loading and helps minimise bearing components wear, extending equipment life |
ADDITIONAL INFORMATION
| •To minimise potential incompatibilities when converting to a new grease, all previous lubricant should be removed as much as possible prior to operation. During initial operation, relubrication intervals should be monitored closely to ensure all previous lubricant is purged |
| •Not to be used in precision and high speed bearings |
