Gear Lubricants


MERCURY GEAR OILS are premium quality industrial gear lubricants made from highly refined base stocks and modern additive technology. These lubricants are designed to provide excellent performance when load carrying capacity is required due to extreme pressures and shock loading.


MERCURY GEAR OILS are designed for industrial enclosed gearing where an AGMA extreme pressure lubricant is specified. Spur, Helical, Bevel and Worm gear configurations subject to heavy loading and shock loading. Bath, Splash, Circulating or Spray mist lubrication as applicable to the required viscosity grade.

Features & Benefits

MERCURY GEAR OILS offer high thermal stability and utilize a modern Extreme Pressure additive system to maintain clean gear and bearing surfaces, minimize deposits, inhibit rust and corrosion and provide excellent water separation.
