Description

BLACK BEAR SERIES “W” HYDRAULIC OILS’ unique extra-active additive formulation virtually eliminates the formation of heat related sludging in sensitive electro hydraulic servos. The premium performance additives incorporated in these oils perform exceptionally well even in fine filtration systems. These oils also exhibit good hydrolytic stability in the presence of water and will not contribute to either the formation of metal etching acids or corrosive reactants.

BLACK BEAR SERIES “W” HYDRAULIC OILS offer exceptional performance in any high output equipment where sustained heat is prevalent. The double compounding of performance additives give these oils optimum antiwear protection and outstanding ASTM D 943 Turbine Oxidation Test performance.
