Description
Castrol Molub-Alloy™ 9002 Heavy is a solvent free open gear lubricant based on a highly refined, viscous, paraffinic
petroleum derivative with excellent oxidation and thermal stability. It is specifically designed to help maximise protection
to open gears and slides on large draglines and shovels while minimising potential pollutants to the environment.
A proprietary blend of Molub-Alloy lubricating solids is included to promote anti-wear and load carrying properties. The
lubricating solids also contribute to the texture of the film surface which is resistant to the adherence of dirt and
environmental contaminants. Molub-Alloy lubricating solids work synergistically with chemical antiwear and extreme
pressure (EP) additives to reduce contact temperatures and wear while providing the ultimate in anti-weld protection
under extreme pressure and shock loading.
Application
Due to the product’s special work-shear/viscosity relationship, it may be used on applications where multiple
viscosities, from light to heavy, have been historically required with conventional open gear compounds and greases.
This range may be used on open gears of all sizes, loads and speeds; on slides, guide rails, cams, and wire ropes.
Mining applications include lubrication of shovels and draglines, on all types of open gears, rails and rollers, bushings,
racks and pinions, dipper sticks and other slides.
Molub-Alloy 9002 Heavy meets P&H 520 specification for use as Multi purpose mining lubricant.
Advantages
Low shear, low friction durable film – even under extreme pressures, the semi-dry working film resists erosion from
rain or sleet, resists peeling in dusty environments, and resists film destruction by contaminating oils and greases
migrating from nearby mechanisms
Simple and economical application – can be applied via automatic dispensing throughout a wide temperature range
Excellent rust and oxidation resistance – protects the equipment and the lubricating film against the elements in
severe climates
Unique compounding technology – flows readily in the film-forming process yet it resists ‘squeeze-out’ and clings
tenaciously even to gear teeth in vertical orientation
