Long-Lasting, Nonmelting Grease Provides Constant Protection for High-Temperature Bearing Applications

Bearings operating in or near heat-generating equipment are subject to temperatures that cause ordinary greases to melt and run, leaving critical bearing surfaces unprotected. Almasol® High Temperature Lubricant is designed to withstand high temperatures, staying in place to provide constant lubrication. It also resists oxidation and vaporization. By ensuring longer lubrication intervals and fewer bearing failures, Almasol High Temperature Lubricant helps contribute to increased production and a healthier bottom line.

Proprietary Additives

N/A LE’s proprietary additivesare used exclusively in LElubricants. Almasol HighTemperature Lubricantcontains Almasol.

Almasol® solid wear reducing additive is able to withstand extremely heavy loads, chemical attack andtemperatures up to 1,900°F(1,038°C). It is attracted to metal surfaces, forming a microscopic layer but not building on itself or affecting clearances. Almasol minimizesmetal-to-metal contact and the resulting friction, heat and wear.

Differential Scanning Calorimetry

N/A DSC is a sophisticated technique for evaluating the oxidation characteristics of a sample of lubricant in a static condition. It is a rapid and reproducible method that measures the heat flow under controlled conditions. Samples are put under pressure in a pure oxygen or air environment and the temperature raised until significant heat flow occurs. This heat flow indicates onset of oxidation. The longer the time taken for heat flow to occurindicates better resistance to oxidation and hence longer lubricant life in the application. Samples may also be run at a fixed temperature and timerecorded until onset of oxidation. While there is no exact correlation to field conditions, several minutes in the DSC represents several hundred hours in operation.

Performance Requirements Met or Exceeded

  • H2


  • Although this product is formulated with inorganic thickeners, it contains petroleum oil which, under very high temperatures, can ultimately form carbon and residues as do other greases with petroleum oils.
  • May show high-starting torques due to heavy oil.

Typical Applications

N/A High-temperature applications, including: asphalt plants,brick/ceramic kilns, exhaust fans, kiln car bearings, lime kilns, oven conveyors, pellet mills, plastics and soot blowers
