Castrol Molub-Alloy OG 936 SF Super Heavy (previously called Molub-Alloy 936 SF Super Heavy) is an open gearlubricant developed specifically for use on heavy duty equipment in mining and industrial services.It is compounded tohelp give maximum protection for gears and slides on large draglines and shovels while minimizing potential pollutantsto the environment. A highly refined,viscous,paraffinic petroleum derivative is the foundation of a blended base fluid withexcellent natural chemical and thermal stability. A proprietary blend of Molub-AIIoy lubricating solids is included topromote anti-wear and load carrying properties beyond those of conventional lubricants. The select lubricating solidswork synergistically with chemical anti-wear and extreme pressure (EP) additives to reduce contact temperatures whileproviding excellent anti-weld protection under extreme pressure and shock loading.
Molub-Alloy OG 936 SF Super Heavy is suitable for use on all types of open gears, rails and rollers, racks andpinions,dipper slicks and other slides on shovels and draglines. It is certified to Bucyrus International SD 4713specification 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 newgears because of the natural occurrence of high spots (asperities) in newly machined surfaces. The lubricating filmmust separate the mating surfaces sufficiently to cushion the effect of the impact of asperities, and inimize initial pittingwhich 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
