Ultra Supreme (#238) is a multi-purpose, tacky, synthetic blend extreme pressure anti- wear grease that is especially formulated for use in all types of heavy duty automotive, construction, mining, farming and industrial equipment that are being used under adverse conditions of excessive pressure, high shock loading, extreme hot and cold temperatures and moisture.
Ultra Supreme is compounded from the finest select high viscosity index solvent refined severely hydro-finished 100% paraffin base stocks and polyalphaolefin (PAO) synthetic base fluids available. Blended into these high viscosity index paraffin base stocks and PAO synthetic base fluid is an aluminum complex base thickener. This aluminum complex thickener allows the Ultra Supreme to exhibit excellent flow and film forming characteristics. This aluminum complex thickener allows the Ultra Supreme to exhibit the following performance features:
Further blended into the high viscosity index 100% paraffin base stocks, PAO synthetic base fluids and the aluminum complex thickener is molybdenum disulfide and a solid lubricant package. The molybdenum disulfide and solid lubricant package allows the Ultra Supreme to act as a "backstop" lubricant when the grease base is either destroyed or wiped away due to unexpected loads, start-up or other conditions which can exceed the capabilities of the grease base's fluid film lubrication. This "backstop" is created by the molybdenum disulfide's and solid lubricant package's natural affinity for metal surfaces. This natural affinity for metal surfaces allows the molybdenum disulfide and solid lubricant package to plate itself to these surfaces in order to form a long lasting solid lubricant film. This solid lubricant film will withstand pressures up to 500,000 pounds per square inch, giving the metal surfaces of the bearings the protection they need during periods of high speed, high shock loads and extreme pressure. The grease's solid lubricant film also helps to reduce friction. This reduction in friction results in reduced wear and a reduction in contact area temperature. This in turn leads to increased equipment, less downtime and extended lubrication cycles.
Ultra Supreme has excellent rust and oxidation inhibiting characteristics, excellent water resistance, shear and mechanical stability, and good pumpability properties. Ultra Supreme also has superior cohesive and adhesive properties. Because of these cohesive and adhesive properties, Ultra Supreme will not wash out, pound out, splatter or squeeze out even under the heaviest loads or vibrations. Due to its superior cohesive and adhesive properties Ultra Supreme is not recommended for use in passenger car automotive wheel bearing applications.
