Description

Castrol Molub-Alloy™OG 936 SF Super Heavy (previously called Molub-Alloy™ 936 SF Super Heavy) is an open gear lubricant developed specifically for use on heavy duty equipment in mining and industrial services.It is compounded to help give maximum protection for gears and slides on large draglines and shovels while minimizing potential pollutants to the environment. A highly refined,viscous,paraffinic petroleum derivative is the foundation of a blended base fluid with excellent natural chemical and thermal stability. A proprietary blend of Molub-AIIoy lubricating solids is included to promote anti-wear and load carrying properties beyond those of conventional lubricants. The select 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.

Application
Molub-Alloy OG 936 SF Super Heavy is suitable for use on all types of open gears, rails and rollers, racks and pinions,dipper slicks and other slides on shovels and draglines. It is certified to Bucyrus International SD 4713 specification for open gear lubricants including electrical hoist drum gear application.
The structural integrity and strength of the lubricating film is particularly valuable in the critical process of sealing 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 inimize initial pitting which could lead to progressive and destructive pitting later.
Molub-AIIoy OG 936 SF Super Heavy may be applied either manually or by heavy duty automatic systems.

Advantages
Forms a tough durable film with ‘cushioning’ effect – even under extreme pressures and at very slow speeds, 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 Excellent rust and oxidation resistance – protects the equipment and the lubricating film against the elements in severe climates.
Compounding technology allows it to flow readily in the film-forming process yet it resists ‘squeeze-out’ and clings tenaciously even to gear teeth in vertical orientation.
Good pumpabilily and set-back resistance – pumpable in heavy automatic lubricating systems and does not heavy up over lime.
Formulated to address environmental concerns- it is free of solvents, lead, antimony and barium.
