Castrol MA OG 8031/3000-00
Castrol Molub-Alloy™ OG 8031/3000 is a high viscosity gel formulated lubricant designed to lubricate large, heavily loaded open gears. The gel technology adds body to the base fluid to form an ultrahigh viscosity lubricant (19,000 mm²/s @ 40°C/104°F) that withstands heavy loads and cushions shock loadings commonly found in open gear applications. A proprietary blend of Molub-Alloy solids works synergistically with chemical reactive extreme pressure (EP) and antiwear (AW) additives to reduce contact temperatures and wear while providing excellent anti-weld protection under extreme pressure and shock loading. Its thixotropic nature allows friction to be reduced to a minimum and enables application by standard spray systems, or use in splash or idler immersion systems; once applied, it forms a thick, tenacious, semi-transparent film on the gear tooth that can be inspected by strobe light during operations. Molub-Alloy OG 8031/3000 is designed to lubricate heavily loaded, low speed open gears, screw type actuators, and low to moderate velocity bushings and bearings operating in the most severely loaded applications equipped with centralised or sump type lubrication systems. It is recommended for use in open gear applications in cement, mining and any other industries requiring antiscuff and anti-wear protection, and where no product build-up is desired, and is also suited for units containing bushings, bearings and/or gears where straight fluid lubricants can leak out.

KEY FEATURES
| •Formulated to minimise distribution line plugging tendency – reduces the potential for eventual plugging of the lubricant distribution lines commonly associated with conventional greases |
| •Readily pumpable and slumpable for good lubricant distribution in enclosed and semi-enclosed applications, and drainable for ease of removal from surrounding guards |
| •Specifically formulated to flush contaminants from gear and pinion flanks, and to resist accumulation in the roots of gear teeth |
| •Highly thixotropic – exhibits a stable form at rest but becomes a fluid when agitated, so it will not run off the gear teeth, while still spreading easily and evenly as the gel-like lubricant liquefies under pressure, carrying away both heat and contaminants |
| •Formulated to address environmental concerns – free of solvents, lead, antimony and Barium |
ADDITIONAL INFORMATION
| •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 |
| •This product was previously called Molub-Alloy 8031. The name was changed in 2015 |
