Molub-Alloy 777-2 ES Castrol
Molub-Alloy 777-2 ES :
Castrol Molub-Alloy 777 ES greases are designed for very heavy duty service in extreme environments.
They are blended and compounded to withstand 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 Molub-Alloy lubricating solids. These lubricating solids 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 to afford effective rust protection and long life of the grease.
Application Of Castrol Molub-Alloy 777-2 ES
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 meet the specification of Bucyrus International (CAT) and Komatsu greases. (with lubricating solids <5% by weight and <10 µm max particle size).
Advantages Of Molub-Alloy 777-2 ES
- 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 and hence extends equipment life
Additional Information Of Molub-Alloy 777-2 ES
In order 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.
