Description

Castrol Molub-Alloy™ 936 SF Heavy Spray is a uniquely compounded 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. Molub-Alloy 936 SF Heavy Spray is designed to meet and is in compliance with the Bucyrus International SD 4713 specification for Open Gear Lubricants. Molub-Alloy 936 SF Heavy Spray is part of Tribol's Eco-SolutionsTM product offering. Formulated to address environmental concerns, Castrol Molub-Alloy 936 SF Spray is free of lead, antimony, barium, and chlorinated solvents. No solvents of any kind are used in 936 SF Heavy Spray. 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 Spray 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.
A proprietary blend of Castrol Molub-Alloy lubricating solids is included to promote antiwear and load carrying properties beyond those of conventional lubricants. The select lubricating solids work synergistically with chemical antiwear and extreme pressure (EP) additives to reduce contact temperatures while providing excellent antiweld protection under extreme pressure and shock loading.
Rust and oxidation inhibitors are included in the formulation to protect the equipment and the lubricating film against the elements in severe climate.

Application

Mining applications include all types of open gears, rails and rollers, racks and pinions, dipper sticks and other slides on shovels and draglines.
Molub-Alloy 936 SF Heavy Spray may be applied either manually or by heavy duty automatic systems.
