BLACK BEAR EP INDUSTRIAL GEAR OILS
BLACK BEAR EP INDUSTRIAL GEAR OILS are premium quality industrial gear lubricants made from highly refined base stocks and modern additive technology. These lubricants are designed to provide excellent performance when load carrying capacity is required due to extreme pressures and shock loading.
High thermal stability and a modern EP additive system delivers gear set efficiencies and maintains clean gear and bearing surfaces minimizing deposits which interfere with effective lubrication.-High oxidation stability limits in-service viscosity increases and promotes long drain intervals- Excellent water separation characteristics and effective corrosion inhibitors protects surfaces from rust corrosion.
BLACK BEAR EP INDUSTRIAL GEAR OILS are recommended for:Industrial enclosed gearing where an AGMA extreme pressure lubricant is specifiedSpur, helical, bevel, and worm gear configurations subject to heavy loading and shock loadingBath, splash, circulating or spray mist lubrication as applicable to the required viscosity grade
