Castrol Optigear™ BM 320 is a high-performance gear oil specifically designed for industrial applications requiring exceptional wear protection and long-lasting lubrication. It features Microflux Trans™ (MFT) technology, which provides advanced surface protection and helps reduce wear caused by surface fatigue, pitting, spalling, scuffing, scoring, or irregularities during the running-in period and normal operations.

Key Features:

• Microflux Trans™ (MFT) Technology: A cutting-edge additive system that reduces wear by improving friction surfaces in a way conventional machining and extreme pressure lubricants cannot. The polarized MFT additives create a passive protective film on friction surfaces before friction occurs and under extreme load conditions, activate to further improve surface quality through plastic deformation, forming long-chain tribopolymers that enhance lubrication.
• High Load Carrying Capacity: With advanced protection against wear and fatigue, Castrol Optigear BM 320 ensures reliable operation under heavy loads.
• Superior Wear Protection: The unique MFT technology provides optimum protection against pitting, scuffing, and other forms of wear.
• Oxidation Resistance: Helps extend oil life by preventing the formation of sludge and deposits.
• Corrosion and Rust Protection: Offers robust protection against corrosion, ensuring long-term reliability.
• Excellent Film Strength: Maintains a strong lubricating film, even under high loads and severe operational conditions.

Additional MFT Technology Benefits:

• Non-sacrificial Micro-smoothing: Unlike conventional lubricants, the MFT technology achieves a micro-smoothing effect on friction surfaces, enhancing the hydrodynamic lubrication film and improving load-carrying capacity.
• Improved Efficiency: The unique tribopolymer system formed by MFT additives reduces friction, providing excellent lubricity and adhesion, which helps maintain machine efficiency and performance.
