Feature and Potential Benefits
Unirex S 2 grease is specially developed for high temperature applications where mineral oil based greases may not provide adequate protection. The ester base fluid has a low volatility at the working temperatures involved, this can lead to long grease life when compared to a conventional mineral oil product. Unirex S 2 is suitable for high temperature operations where frequent relubrication is not practical.
This product offers the following performance features:
• Outstanding high-temperature performance with better lubricity and wear protection than conventional grease
• Low base stock volatility helping to provide long lubricant life and potentially extend re-lubrication intervals.
• An upper operating temperature of 200º C /392°F based upon ASTM D3336 High Temperature Life performance
Applications
Application notes: The ester base oil of Unirex S 2 is not compatible with many common elastomer seal materials. For example, it may cause a softening or swelling of NBR seals. It is recommended that the equipment manufacturer or your ExxonMobil representative be consulted regarding seal compatibility in a specific application.
Unirex S 2 is recommended by ExxonMobil for severe applications including:
• Conveyor bearings in kilns and ovens
• Steel mill ladle bearings
• Jet aircraft starter clutch assemblies
• Critical oven bearings in Fiberglas manufacture
