CASTROL MOLUB-ALLOY 936 SF HEAVY

Castrol Molub-Alloy™ 936 SF Heavy is an open gear lubricant developed specifically for use on heavy duty equipment in mining and industrial service. Molub-Alloy 936 SF Heavy is compounded to give maximum protection to gears and slides on large draglines and shovels while minimizing potential pollutants to the environment. A proprietary blend of Molub-Alloy lubricating solids is included to promote anti-wear and load carrying properties. These lubricating solids work synergistically with chemical anti-wear and extreme pressure (EP) additives to reduce contact temperatures while providing excellent anti-weld protection under extreme pressure and shock loading. The structural integrity and strength of the lubricating film is particularly valuable in the critical process of seating new gears because of the natural occurrence of high spots (asperities) in newly machined surfaces. The lubricating film must separate the mating surfaces sufficiently to cushion the effect of the impact of asperities, and thus minimize initial pitting which could lead to progressive and destructive pitting later. A highly refined, viscous, paraffinic petroleum derivative is the foundation of a blended base fluid with excellent natural chemical and thermal stability. Molub-Alloy 936 SF Heavy is compounded to flow readily in the film-forming process; yet it resists "squeeze-out" and clings tenaciously even to gear teeth in vertical orientation. Rust and oxidation inhibitors are included in the formulation to protect the equipment and the lubricating film against the elements in severe climate. Application Molub-Alloy 936 SF Heavy is suitable for use on all types of open gears, racks and pinions and sliding or skidding applications like in Draglines and Shovels. it can be applied either manually or by heavy duty automatic systems. This product is used extensively in mining, construction, onshore drilling operations and on offshore installations facilitating effective lubrication and protection on: Rack and pinion jacking mechanisms. Cantilever skidding systems. Mooring winch open gearing and slides. FPSO offloading systems. Crane slew ring & pinion. Exposed threads on penstock valves. Heavy duty top dressing for the ultimate protection of wire ropes Molub-Alloy 936 SF Heavy is designed to meet and is in compliance with the Bucyrus International SD 4713 specification (CAT) and Komatsu specifications for Open Gear Lubricants. Advantages Formulated to address environmental concerns - it is free of solvents, lead, antimony and barium Forms tough durable film with "cushioning" effect, even under extreme pressures and at very slow speeds; film resists erosion from rain or sleet, and resists peeling in dusty environments Resists film destruction by contaminating oils and greases migrating from nearby mechanisms
