Exxon (now Mobil) Unirex S 2 is an NLGI Grade 2, lithium complex thickened, high temperature synthetic grease. It is formulated from a low volatility, synthetic polyol ester fluid, fortified with performance-enhancing additives. It is uniquely suited for high temperature applications, with an upper operating temperature recommendation of 200º C / 392°F (based upon ASTM D3336 performance).

Unirex S 2 is recommended for severe applications including: Conveyor bearings in kilns and ovens, steel mill ladle bearings, jet aircraft starter clutch assemblies, critical oven bearings in Fiberglass manufacture, etc. The ester base oil of Unirex S 2 is not compatible with many common elastomer seal materials (such as NBR). It is recommended that the equipment manufacturer or your ExxonMobil representative be consulted regarding seal compatibility in a specific application.

Product Data Sheet

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

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
