Mobil Glygoyle™ Series lubricants are supreme performance gear, bearing and compressor oils designed to provide outstanding benefits in terms of efficiency, long oil life, and equipment protection. These fully synthetic, polyalkylene glycol (PAG) lubricants were developed for use under operating conditions beyond the capabilities of other synthetic lubricants and mineral oils. Their low pour points ensure excellent low-temperature fluidity. The ISO 150 to 1000 grades are NSF H1 registered lubricants and also comply with Title 21 CFR 178.3570 by the Food and Drug Adminstration (USA) for lubricants with incidental food contact.
– Exceptional EP/antiwear protection for critical equipment components
– A high level of micropitting protection for sensitive gear systems
– Protection against rust and corrosion in-service
– Resistance against foam buildup
– Excellent lubricity inherent to this fully synthetic lubricant
– Low traction coefficient resulting in increased energy efficiency and reduced bulk oil/system temperatures
– Very good thermal and oxidative stability to reduce sludge formation and deposits
Features and Benefits
The Mobil Glygoyle Series of fully synthetic oils are specifically designed to outperform mineral and PAO synthetic lubricants in gear and hydrocarbon gas compression applications. In worm gears, the unique properties of these oils allows for more torque to be put through the reducer while in many cases lowering the operating oil sump temperature correlating to longer seal, oil, and gearbox life. In gas compressors, the limited solubility of hydrocarbons in the Mobil Glygoyle Series allows for reduced lubricant dilution and enhanced equipment protection.
Features compared to other mineral, synthetic, and PAG lubricants:
General: There are various types of PAG base oils. The inherent properties of these oils can differ depending on the raw materials and processes used in their manufacture. Features that can differ among various PAG oils include their traction coefficient (energy efficiency), thermal conductivity, and solubility with hydrocarbon oils, tendency to attract water, and low temperature properties.
High Efficiency: ExxonMobil researchers have selected PAG base oils which provide high levels of energy efficiency relative to mineral, PAOs, and other PAG oils. This, coupled with an increased thermal conductivity of about 10% over mineral and PAO oils, leads to lower operating temperatures and longer component life.
Wide Temperatures: The Mobil Glygoyle Series has very high VIs ranging from 170 for the ISO 68 to 285 for the ISO 1000. This leads to a wide operating temperature range, beyond that of mineral and PAO lubricants.
Rust Protection: PAG lubricants, which are designed to be immiscible with hydrocarbon oils, tend to absorb water more than mineral or PAO oils. Because of the potential for high water-in-oil levels, care must be taken to prevent the formation of rust on equipment. Mobil Glygoyle Series oils pass major rust tests such as the ASTM D665A and Bethlehem Steel rust test parts A/B, and receives 0,0 ratings in the DIN 51802 Emcor rust test with distilled water. In addition, they show good yellow metal compatibility with a 1B rating in the ASTM D130 test. Mobil Glygoyle Series is not recommended for use in areas where saltwater contamination is expected.
Foam Control: Foam control is important, especially in boxes that are “Sealed for Life”. Mobil Glygoyle Series provides excellent results in all three sequences of ASTM D 892 Foam Test.
EP/antiwear: Having the right blend of EP/AW protection is important, especially in worm gears that contain bronze and other yellow metals. The Glygoyle Series of lubricants show excellent EP/antiwear protection with typical results of 12+ in the DIN 51354-2 FZG scuffing test, very low cage and roller wear in the DIN 51819-3 FAG FE8 test, and excellent micropitting protection with a result of ›10-high in the FVA 54 micropitting test (ISO 320).
• High thermal and oxidative stability as well as excellent antiwear protection, Provides outstanding gear protection under severe load factor situations, Increased production because of extended lubricant life, reducing scheduled and unscheduled downtime for routine lubricant changes, Lower maintenance costs and replacement expenditures
