Based upon highly refined mineral oil, enhanced with sulphur/phosphorus extreme pressure additive technology providing outstanding thermal stability and high load carrying capacity. Recommended for the lubrication of industrial gear boxes using forced circulation or splash and oil bath lubrication. They may be used for the lubrication of spur and helical gears and in some lightly loaded worm type gear applications. Excellent viscosity characteristics ensure that starting torques are not excessively high in cold operating conditions.
