Gear Oil Alcat 50 is a special oil for hydraulic and transmission applications, based on solvent-refined base oils, supplemented with additives to achieve the following properties:

  • A very low pour point
  • Excellent oxidation stability
  • Good wear resistance, as a result of which the final drives achieve a longer service life
  • Special friction properties that ensure optimal use of powershift transmissions
  • Suitable for systems with wet brakes
  • Outstanding resistance to rust and corrosion


Gear Oil Alcat 50 has been specially developed for the lubrication of powershift transmissions, differentials, final drives and hydraulic systems in earth moving equipment for which oil is recommended that complies with the Caterpillar TO-4 or Allison C4 specifications.
