Castrol Optigear™ SYN X 320 is a fully synthetic, high-performance gear oil specifically formulated for industrial gear systems requiring extended oil life and superior wear protection. It combines synthetic hydrocarbons with a unique plastic deformation (PD) and surface improvement additive package, providing exceptional performance under severe operating conditions.

Key Features:

• Synthetic Hydrocarbon Base: Formulated with synthetic hydrocarbons for enhanced thermal stability and superior performance compared to mineral-based oils.
• Plastic Deformation (PD) Technology: The special additive package is activated under high specific loads and corresponding temperatures, helping to equalize surface roughness through plastic deformation without causing abrasion, leading to surface improvement and enhanced protection.
• Extended Oil Life: Advanced synthetic formulation provides excellent oxidation stability, extending oil drain intervals and reducing overall maintenance costs.
• Exceptional Wear Protection: Protects against micro-pitting, scuffing, and other forms of wear, ensuring the long-term reliability of gears and bearings.
• High Load Carrying Capacity: Ensures efficient protection of heavily loaded gearboxes and equipment.
• Energy Efficiency: The synthetic composition reduces friction, improving energy efficiency and operational performance.
• Low-temperature Fluidity: Maintains fluid performance even in low temperatures, ensuring reliable start-ups in cold environments.
