Open Gear Lube

Chlorine-Free, Solvent-Cutback Open Gear Lubricant

Phillips 66®Open Gear Lube is a viscous, tacky, petroleum resin-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 on mining shovels, draglines and excavation equipment used in underground and surface mines and in rock quarries. It also may be used for the lubrication of some cable-actuated equipment.

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

• 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 found on mining shovels, draglines and excavation equipment

• Guides and sliding surfaces with large clearances, where asphaltic-type lubricants are specified

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