CASTROL OPTIGEAR SYNTHETIC A 320

Why Choose Castrol?

Castrol products offer a range of benefits for high intensity gear applications. Castrol Optigear Synthetic A 320 delivers outstanding wear protection and surface smoothing benefits, which helps to extend equipment life even under heavy or shock loads. Its superior thermal and oxidative stability makes it ideal for use in harsh environments and temperature extremes.

The Castrol Optigear Synthetic A range consists of fully synthetic high performance gear oils with Microflux Trans additives, which offer optimum wear protection under very extreme thermal loads and operating conditions such as vibrations, oscillating motions and shock loads.

With this strong foundation of state-of-the-art technology, this high-performance synthetic gear oil goes beyond standard gear protection. Optigear is designed for enclosed industrial gearboxes, including spur, helical and bevel gears that operate under heavy loads or require extended service intervals. Its wide operating temperature range and excellent low-temperature flow characteristics make it particularly suitable for outdoor installations and applications subject to fluctuating climates.

The Microflux Trans additive technology chemically reacts under load and expands to create a smooth, wear-resistant film that reduces friction and improves efficiency. This surface polishing effect helps to lower energy consumption and extend the operational life of gear components, even in systems subject to high loads, micro-pitting or extreme pressures.

This product also offers excellent corrosion protection, low foaming characteristics and superior water separation. These properties contribute to stable performance over long operating cycles and help maintain the integrity of metal surfaces, bearings and seals.

Advantages

• Excellent low-temperature behaviour enables easy starting and reliable fluidity at extremely low temperatures.
• Optimum wear protection thanks to the smoothing Microflux Trans additives, which avoid pitting and scoring.
• A low coefficient of friction delivers reduced energy costs and lower oil temperatures.
• A significantly extended oil change interval reduces maintenance costs.
