Description
Castrol Optigear Synthetic A 320 is a premium industrial gear lubricant based on polyalphaolefin (PAO) synthetic base oils enhanced with Castrol’s MicroFlux TRANS® additive technology, which actively adapts to operating conditions to deliver superior protection under high loads, thermal stress, vibrations and shock loads. The advanced formulation helps minimise wear and micro-pitting, supports fluid performance across a wide temperature range, and maintains good low-temperature fluidity for easier start-up in cold conditions.
This 20 L canister size is suitable for refilling smaller industrial gearboxes and enclosed drives in equipment such as wind turbines, conveyor and crane gears, elevators, rolling mills, robot joints, and more. The synthetic base and additive combination provide high load-carrying capacity, excellent corrosion resistance, and extended oil life, which can help reduce maintenance intervals and improve equipment reliability.
Key Features
