Versatile Grease with Calcium Sulfonate Complex Thickener Protects Equipment from Heat, Moisture & Heavy Loads

Lubrication Engineers, Inc. formulated Monocal® GP Grease for use in environments with challenging conditions such as high temperatures, heavy loads and the presence of water. Its high-performance formula features high-viscosity base fluid, calcium sulfonate complex thickener and Monolec®, LE’s proprietary wear-reducing additive. Available in NLGI 2 and 1 grades, this premium combination imparts a very high dropping point, exceptional inherent extreme pressure (EP) characteristics, superior mechanical stability, low oil bleed, and water resistance – everything you need to protect and extend the life of your equipment.

A versatile general purpose lubricant, Monocal GP Grease is the right solution for industrial and mobile equipment used in a wide variety of industries. It is especially effective when used on bearings operating in a warm, moist environment or in operations where a lot of water is needed to keep equipment cool. Without effective, reliable lubrication, these conditions can lead to costly downtime and repairs.

Beneficial Qualities

N/A High-performance formula
  • Performs effectively in severe conditions such as heat, water and heavy loads
  • Provides long-lasting reliable protection
  • Ensures very low oil separation
  • Features high-viscosity base fluid (ISO 220)

Calcium sulfonate thickener
  • Inherently prevents rust and corrosion – even in sea water
  • Has very high dropping point as compared to conventional thickeners
  • Ensures excellent mechanical stability for long-lasting use
  • Imparts outstanding EP properties (without the addition of heavy metals), providing protection even when pound-out conditions occur

Wear-reducing additive
  • Protects against wear, metal-to-metal contact and scoring
  • Provides exceptional film strength
  • Resists oxidation and water contamination
  • Maintains consistency after repeated heating and cooling

Available Grade

  • NLGI 1

Proprietary Additives

N/A LE’s proprietary additives are used exclusively in LE lubricants. Monocal™ GP Grease contains Monolec.

Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
