MPAO Heavy-Duty Gear Oil
High-performance industrial gear oil engineered for extreme heavy-duty applications, delivering superior extreme pressure and anti-wear protection with extended service life.
Product Overview
ARNOCO mPAO Heavy-Duty Gear Oil is refined using high-quality base oils and advanced mPAO (metal deactivator extreme pressure anti-wear) additive technology. It delivers exceptional extreme pressure and anti-wear performance, thermal-oxidative stability, and rust and corrosion protection to effectively safeguard gear surfaces from wear, pitting, and scuffing damage.
Ideal for closed-loop gear transmission systems in heavy-duty, impact-load applications such as mining machinery, wind power generation, cement equipment, steel rolling mills, and papermaking machinery. Significantly extends equipment lifespan and reduces maintenance costs.
Core Advantages
Extreme pressure anti-wear protection
Uses mPAO composite additive technology to form a tough, resilient oil film under heavy-load conditions, effectively preventing gear tooth wear and pitting.
High-temperature stability
Excellent thermal-oxidation stability maintains oil performance at high temperatures and extends oil change intervals.
Wide Applicability
Suitable for various industrial closed gear drive systems, including heavy industries such as mining, cement, and steel.
