 Castrol Molub-Alloy 882 EP Open Gear Greases are multi-functional lubricants developed to provide the extra protection required to lubricate surfaces that are subjected to extreme rubbing action and contact pressures. Typical applications include machine ways and guides, transfer slides, acme threads, gear racks and open gear drives. They may also be used in heavily loaded, slow rotating components such as plain spherical bearings, plain bearings and bushings. When properly applied, Molub-Alloy 882 EP Open Gear Greases form a tenacious semi-dry coating that is highly resistant to water wash and debris buildup.
A select petroleum oil of high viscosity, modified with other petroleum derivatives forms an exceptionally tough film in service, which, even at elevated temperatures, resists the thinning and hardening associated with conventional pastes and asphaltic type compounds.
A proprietary blend of Castrol Molub-Alloy solid film lubricants constitutes a major part of Molub-Alloy 882 EP Open Gear Greases. They function synergistically with additional extreme pressure components to provide the necessary protection in severe service. Even the unique thickening system in these greases is a contributing solid lubricant.
Components are selected for the manufacture of Molub-Alloy 882 EP Open Gear Greases based on quality, compatibility, and particularly for their intended use. The Molub-Alloy Solid Lubricants are of a proven combination and size distribution for use on sliding mechanisms subjected to high contact pressures.
Extreme pressure properties are maximized by the use of the most effective, non-corrosive EP agents available. They complement the anti-wear, anti-seize performance of Castrol Molub-Alloy solid lubricants in protecting against severe load conditions and in higher than normal ambient temperatures.
Components, including the thickening system, were selected to constitute a product which will not drip or fling-off even at very high temperatures (over 400°F). |
Applications:
Typical applications for Molub-Alloy 882 EP Open Gear Greases include open gears subjected to high torque and slow surging loads, and guide devices such as metal forming press slideways and the tie bars of die casting machines. They are especially suitable for use in applications involving elevated ambient temperatures or water wash conditions.
Application of Molub-Alloy 882 EP Open Gear Greases may be by brush, paddle, or pressurized lubrication spraying devices. Where dispensing lines are long or ambient temperatures low, the use of Castrol Molub-Alloy 882 EP Arctic is suggested. |
