This product is formulated using a deeply refined, high-viscosity base oil, combined with premium-grade additives that offer exceptional extreme-pressure, anti-wear, antioxidant, rust-inhibiting, and anti-corrosion properties—carefully blended through advanced manufacturing processes.

Product Performance

Excellent extreme-pressure and anti-wear performance, along with superior load-carrying capacity, help minimize gear surface scoring, effectively reduce noise, and extend equipment service life.

Excellent oxidation stability and thermal stability extend the service life of the oil;

Excellent anti-foaming properties provide effective oil film protection, delivering outstanding lubrication and heat dissipation.

Excellent corrosion and rust prevention, along with superior demulsibility, ensures effective water separation even in humid environments, safeguarding components from rust and corrosion.

Technical Specifications

GB 5903-2011

Scope of Application

Suitable for heavy-duty closed gear systems—such as conveyors, coal mills, extruders, and mixers—in industries like steel, cement, and mining, where the tooth surface contact stress exceeds 1.1 GPa.

Instructions for Use and Precautions

According to equipment lubrication guidelines, select oil products with appropriate viscosity. During use and storage/transportation, prevent contamination by foreign objects, and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines—and never mix it with oils of different types.
