Assess the conditions in which the grease will perform
  • High and/or low temperatures
  • Load and pressure (look for extreme pressure, anti-wear additives)

    The thickener is what holds the lubricant in place.

    • Must be compatible with the equipment manufacturer recommendations
    • Types of thickeners
