OVERVIEW 

BLACK BEAR HIGH TECH MULTI-GRADE ANTI-HEAR HYDRAULIC OILS are designed to meet the most stringent requirements of hydraulic pump manufacturers such as Vickers, Commercial Shearing, Denison, Sunstrand, and Racine. They contain a careful balance of thermally stable and anti-wear zincs which will reduce vane pump wear to a minimum, yet will not be corrosive to bronze or brass components. They will perform exceptionally well in systems with heavily loaded pumps operating under extremely high pressures (over 3000 psi), high speeds or high temperatures. Pump life in such systems will be increased significantly. Formulated from selected base stocks, BLACK BEAR ANTI-WEAR HYDRAULIC OILS will afford extremely good rust protection, demulsibility, anti-foam properties and high viscosity-temperature (VI) relationships. Viscosity index range from 147 for the 135C Series to 178 for the 125C formulation. This enables the oils to resist wide changes in viscosity throughout the normally encountered operating temperatures. Low pour points provided a ready flow of fluid during cold weather start up. Another unique advantage in using our BLACK BEAR ANTI-WEAR HYDRAULIC OILS is its special seal conditioner. Carefully blended into the formulation, this effective additive restores the plasticizer in the seal which can be leached out due due to constant high temperature of hydraulic operation. Without this conditioner, seals can tend to shrink and become hard and brittle. This can result in hydraulic oil leakage -- leading to costly downtime and seal replacement. For trouble-free euipment life and low cost operation, BLACK BEAR ANTI-WEAR HYDRAULIC OILS are highly recommended.
