Description

Castrol Molub-Alloy™ 936 SF Heavy A is a uniquely compounded solvent free open gear lubricant developed specifically for use on heavy duty equipment in the extremes of environments. It is compounded to give maximum protection whilst minimizing potential pollutants to the environment. A highly refined, viscous, paraffinic mineral oil 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. 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 minimize initial pitting which could lead to progressive and destructive pitting later.

Application

Molub-Alloy 936 SF Heavy A is suitable for use on all types of open gears, racks and pinions and sliding or skidding applications, 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.
