CASTROL Molub-Alloy 936 SF Light

Description

Castrol Molub-Alloy 936 SF Light (Solvent-Free) lubricants are uniquely compounded open gear lubricants developed

specifically for use on heavy duty equipment in mining and industrial service. Molub-Alloy 936 SF is compounded to give

maximum protection to gears and slides on large draglines and shovels while minimizing potential pollutants to the

environment. Molub-Alloy is designed to meet the Bucyrus International SD4713 specification for open gear lubricants.

Molub-Alloy 936 SF Light is part of Castrol Performance Lubricants’ Eco-Solutions product offering. Formulated to

address environmental concerns, Molub-Alloy 936 SF Light is free of lead, antimony, barium, and chlorinated solvents. No

solvents of any kind are used in 936 SF. The product is available in grades Light and Heavy.

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 936 SF Light 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.

A proprietary blend of Castrol Molub-Alloy lubricating solids is included to promote antiwear and load carrying properties

beyond those of conventional lubricants. The select lubricating solids work synergistically with chemical antiwear and

extreme pressure (EP) additives to reduce contact temperatures while providing excellent antiweld protection under

extreme pressure and shock loading.

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

elements in severe climate.

Application

Mining applications include all types of open gears, rails and rollers, racks and pinions, dipper sticks and other slides on

shovels and draglines.

Molub-Alloy 936 SF Light may be applied either manually or by heavy duty automatic systems.

Advantages

• Compounded for the protection of the ecology, the elimination of materials considered to be hazardous.

• 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.
