| Molub-Alloy™ OG 8031-2200 & 3000Open gear lubricantDescriptionCastroI Molub-Alloy™ OG 8031/2200 and Molub-Alloy™ OG 8031/3000 are high viscosity gel formulated lubricantsdesigned to lubricate large heavily loaded open gears. The gel technology adds body to the base fluid to form anultrahigh viscosity lubricant (@40ºC/104ºF 18,500 and 19,000 mm2/s respectively) to withstand heavy loads andcushions shock loadings commonly found in open gear applications.A proprietary blend of Molub-Alloy solids working synergistically with chemical reactive extreme pressure (EP) andantiwear (AW) additives combine to reduce contact temperatures and wear while providing excellent anti-weld protectionunder extreme pressure and shock loading.The thixotropic nature of Molub-Alloy OG 8031 allows friction to be reduced to a minimum and aids in its ability to beapplied by standard spray systems or used in splash or idler immersion systems.Once applied to the gear surface the Molub-Alloy OG 8031 forms a thick tenacious semi-transparent film on the geartooth that can be inspected by strobe light during operations.ApplicationMolub-AIIoy OG 8031 is designed to lubricate heavily loaded, low speed open gears, screw type actuators, and low tomoderate velocity bushings and bearings operating in the most severely loaded applications equipped with centralisedor sump type lubrication systems.This range is recommended for use in open gear applications in cement, mining and any other industries requiringantiscuff and anti-wear protection, and where no product build up is desired. It is also suited for units containingbushings, bearings and/or gears where straight fluid lubricants can leak out.AdvantagesFormulated to minimise distribution line plugging tendency – minimises the potential for eventual plugging ofthe lubricant distribution lines commonly associated with conventional greasesReadily pumpable and slumpable for good lubricant distribution – good lubricant distribution in enclosed andsemi-enclosed applications, and drainable for ease of removal from surrounding guardsSpecifically formulated to flush contaminants from gear and pinion flanks, and to resist accumulation in theroots of gear teethHighly thixotropic – exhibits a stable form at rest but becomes a fluid when agitated, therefore will not run off thegear teeth. However, it will still spread easily and evenly since the gel-like lubricant liquefies when pressure isapplied, carrying away both heat and contaminantsFormulated to address environmental concerns - free of solvents, lead, antimony and BariumPage: 1/3Typical CharacteristicsName Method Units 8031/2200-00 8031/3000-00Appearance Visual - Dark and Opaque Dark and OpaqueThickener Type - - Inorganic InorganicBase Oil Type - - Mineral Oil Mineral OilNLGI Grade - - 00 00Density at 20°C/68°F ASTM D 1475 - 0.937 0.941Base Fluid Flash Point ASTM D92/ISO 2592 °C/°F 225/437 218/425Worked Penetration, 60 Strokesat 25°C/77°FASTM D217/ISO 2137 0.1mm 400-430 400-430Product Viscosity @ 40ºC/104ºFDSR* DIN EN 13702 mm²/s approx 18500 19000Product Viscosity @ 100ºC/212ºFDSR* DIN EN 13702 mm²/s approx 9400 8500Base Oil Viscosity at 40°C/104°F ASTM D445/ISO 3104 mm²/s 2200 3000Copper Corrosion, 24hrs100°C/212°FASTM D4048/ISO 2160 Rating 1b 1bFour Ball EP Test, Load Wear Index ASTM D2596 kg 66 88Four Ball EP Test, Weld Load ASTM D2596 kg 400 400Brookfield Viscosity, Spindle No.7,10 rpm at 25°C/77°F - cP 76000 80000FZG Test, A/2.76/50 Method,Failure Stage DIN 51354 Rating >12 >12Pumpability by Lincoln Ventmeter,at -1°C/30°FUS Steel Psi180 210Pumpability by Lincoln Ventmeter,at -7°C/20°F 350 440Pumpability by Lincoln Ventmeter,at -12°C/10°F 830 840DIN Classification DIN 51826 - - OGPF 00 K-20ISO Classification ISO 6743/9 - L-XCBFB 00 L-XBCGB-00*DSR: Dynamic shear rheometerSubject to usual manufacturing tolerances |
