Abstract
Lubricant compositions having improved load carrying capacity comprising an extreme pressure compound comprising a sulfur-containing compound, a load carrying capacity enhancing combination comprising a hydrocarbylamine compound and an alkylphosphorothioate compound, a friction modifier compound, and a diluent or base oil as applicable. These lubricant compositions can be used as industrial oils well-suited for the demands of geared device applications, such as in wind turbine gear-boxes and automotive gears and axles.
