Description

Castrol Molub-Alloy™OG 936 SF Heavy A (previously called Molub-Alloy 936 SF Heavy A) is a uniquely compounded solvent free open gear lubricant developed specifically for use on heavy duty equipment in mining and industrial service.
It is compounded to give maximum protection to gears and slides on large draglines and shovels while minimising 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-Alloy 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 Heavy A is suitable for use on all types of open gears, rails and rollers, racks and pinions, dipper sticks and other slides on shovels and draglines. It is certified to Bucyrus International SD 4713 (CAT) specification for open gear lubricants.
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 minimise initial pitting which could lead to progressive and destructive pitting later.
Molub-Alloy OG 936 SF Heavy A may be applied either manually or by heavy duty automatic systems
