Castrol Molub-Alloy 936 SF Heavy A Open Gear Lubricants
Description
Castrol Molub-AlloyTM 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 minimizing 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.Additional Information

| Additional Information | In order to minimise potential incompatibilities when converting to a new grease, all previous lubricant should be removed as much as possible prior to operation. During initial operation, relubrication intervals should be monitored closely to ensure all previous lubricant is purged., In order to minimize potential incompatibilities when converting to a new grease, all previous lubricant should be removed as much as possible prior to operation.

| Features and Benefits | In order to minimise potential incompatibilities when converting to a new grease, all previous lubricant should be removed as much as possible prior to operation. During initial operation, relubrication intervals should be monitored closely to ensure all previous lubricant is purged., Forms a tough durable film with ‘cushioning’ effect – even under extreme pressures and at very slow speeds, the semi-dry working film resists erosion from rain or sleet, resists peeling in dusty environments, and resists film destruction by contaminating oils and greases migrating from nearby mechanisms., Excellent rust and oxidation resistance – protects the equipment and the lubricating film against the elements in severe climates., Unique compounding technology – flows readily in the film-forming process yet it resists ‘squeeze-out’ and clings tenaciously even to gear teeth in vertical orientation., Good pumpability and set-back resistance – pumpable in heavy automatic lubricating systems and does not ‘heavy up’ over time., Formulated to address environmental concerns – it is free of solvents, lead, antimony and barium. |
