Royal Ultra 865M and 865HD Calcium Sulfonate Complex Greases are approved by CAT and Komatsu as a CLS (Central Lube System) Grease

Long-term lubrication by grease is an important problem with respect to effective use of natural resources and extending the life of machines. The solution to this problem is extension of the grease life. Heat and shear result in deterioration of grease by one of two deterioration types. The first type is where the grease becomes soft and flows out of the lubrication area, while the second is where the grease solidifies and can no longer supply oil to the lubrication area. Long-term lubrication grease therefore must have high heat resistance and shear stability.
Calcium sulfonate complex greases have higher performance compared to metal soap greases such as lithium and aluminum complex greases, especially with respect to heat resistance, load carrying capacity, water resistance, shear stability, and corrosion resistance. They can be used above 160 degrees C. These characteristics have led to extensive use of calcium sulfonate complex greases in the following industries:

  • Marine
  • Iron and steel
  • Mining
  • Off-Road Construction
  • Pulp and paper
  • Power Generation including wind turbines
  • Motorized steam valves

Calcium Sulfonate greases offer the following performance advantages:

  • excellent EP specifications
  • excellent wear specifications
  • excellent corrosion resistance
  • wide-temperature advantages
  • excellent water washout resistance (much higher than any lithium or aluminum complex greases)
