CASTROL Molub-Alloy OG 936 SF Heavy Spray

Description

Castrol Molub-Alloy™ OG 936 SF Heavy Spray (previously called Molub-Alloy™ 936 SF Heavy Spray) is an open gear

lubricant developed specifically for use on heavy duty equipment in mining and industrial service. Molub-Alloy OG 936 SF

Heavy is compounded to help give maximum protection to gears and slides on large draglines and shovels while

minimizing potential pollutants to the environment.

A proprietary blend of Molub-Alloy lubricating solids is included to promote anti-wear and load carrying properties.

 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 extremepressure 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 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 OG 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.

Rust and oxidation inhibitors are included in the formulation to protect the equipment and the lubricating film against the

elements in severe climate.

Application

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

applications like in Draglines and Shovels.

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.

Advantages

Formulated to address environmental concerns - it is free of solvents, lead, antimony and barium

Forms tough durable film with "cushioning" effect, even under extreme pressures and at very slow speeds; film

Resists erosion from rain or sleet, and resists peeling in dusty environments

Resists film destruction by contaminating oils and greases migrating from nearby mechanisms

Additional Information

Molub-Alloy OG 936 SF Heavy Spray was not intended for general use in bushings and bearings except in slow moving

heavily loaded applications. Contact Castrol Engineering for all new applications in bearings.
