Gear Shield®

Chlorine-Free, Solvent-Cutback Open Gear Lubricant

Phillips 66®Gear Shield is a viscous, adhesive, petroleum resin/asphaltic-based gear lubricant cut back with a volatile, non-chlorinated solvent 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. It also may be used for the lubrication of some cable-actuated equipment, such as marine winches.

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 specified

• Cables on draglines, clamshells, shovels, hoists and other cable-operated equipment where cable clamp safety devices are not used
