Industrial gear oils are high performance mild Extreme-Pressure fluids developed for industrial gearboxes, especially for industrial applications such as oil bath lubrication of heavy and/or shock loaded gear drives, worm wheel gears and circular lubrication. Industrial gear oil is based on high quality mineral base oils, in combination with a performance additive package, to offer an excellent protection against oxidation, extend equipment lifetime, low foam tendency and very good antiwear properties.
