Phillips 66® Gear Shield Synthetic is a viscous, adhesive, transparent synthetic based gear lubricant with a low viscosity sacrificial diluent for ease of application. It is recommended primarily for the lubrication and cushioning of open and semi-enclosed gears found on stationary equipment, such as ball and rod mills, kilns and paper mills.

Features & Benefits

  • Excellent adhesion to metal surfaces
  • Forms a heavy, tenacious film to lubricate and cushion gear teeth
  • Good extreme-pressure properties for protection under heavy or shock loads
  • Good resistance to water washout
  • Protects against rust and corrosion
  • Will not flake off at low temperatures
  • Drains freely from gear guards
  • Does not contain any chlorine, lead or carcinogens
  • Easy application, by spraying, brushing or dripping
  • Suitable for use with automatic lubrication equipment


  • Open and semi-enclosed gears, such as those found on mining ball and rod mills, cement mills, drying kilns, and papermaking machinery and presses
  • Mills used to process minerals such as gold, copper, iron, taconite and phosphate
  • Guides and sliding surfaces with large clearances, where asphaltic-type lubricants are specifi ed
  • Cables on draglines, clamshells, shovels, hoists and other cable-operated equipment where cable clamp safety devices are not used
