Product Description

GEARGARD™ is a high performance, semi synthetic lubricant designed for use on open gears in grinding mills (Rod, Ball and SAG mills). GEARGARD is formulated with a high flash point non-chlorinated diluent to facilitate dispensing through typical mill auto-greasing systems. After application, the solvent is designed to evaporate, leaving an adhesive and cohesive high-viscosity lubricating film. GEARGARD contains additives that provide potent extreme-pressure (EP) protection and excellent rust and corrosion prevention characteristics.


Features and Benefits

GEARGARD is designed with the following special features:

  • Adhesive lubricant fortified with high viscosity synthetics
  • Potent EP properties and excellent rust protection
  • Excellent scuffing and scoring protection as demonstrated by the 13+ FZG load stage
  • Contains a solvent to facilitate application
  • Provides a robust high viscosity film on the metal surface
  • Designed to flow freely from gear guards



GEARGARD can be mopped, poured, dripped or sprayed onto the points to be lubricated.

GEARGARD is designed to meet the requirements of major mill and gears manufacturers including Falk Corp., FFE Mineral and Svedala Industries (Dominion, Boliden - Allis). Contact Imperial Oil marketing technical services for further information when considering GEARGARD for shovel applications.
