Gear oil 220 and 320 differ mainly in viscosity, where 220 suits moderate conditions and 320 delivers stronger load protection for heavy-duty industrial gear systems.

Gear oils are essential in industrial lubrication systems, and both ISO VG 220 and ISO VG 320 formulations are widely used across machinery powered by advanced lubricant systems from Shell, Mobil, and TotalEnergies. These formulations are designed to reduce friction, prevent wear, and maintain stable performance in enclosed gear systems across manufacturing and heavy industry.

Gear Oil 220 has a lower viscosity at 40°C (220.3 cSt), making it more fluid and suitable for moderate loads and cooler operating environments. In contrast, Gear Oil 320 (319.4 cSt) is thicker, providing enhanced cushioning for heavy-duty applications where shock loads and higher operating stress are common. Both grades maintain strong corrosion resistance and pass high-performance wear protection standards, often benchmarked in systems using Molykote and maintenance-focused solutions from CRC.

From a thermal perspective, both oils offer stable performance, with 320 providing slightly higher flash resistance, making it more suitable for high-load, high-temperature industrial gearboxes. Meanwhile, 220 performs efficiently in colder conditions where fluidity is critical for startup lubrication.

Key differences:

• Gear Oil 220: Lower viscosity, better flow in cold conditions, ideal for moderate loads
• Gear Oil 320: Higher viscosity, stronger load cushioning, ideal for heavy-duty systems
• Both: Strong corrosion resistance and wear protection performance
• Both: Suitable for industrial gear systems across manufacturing and energy sectors

Selecting the correct grade ensures optimal efficiency, reduced wear, and extended machinery lifespan, especially in industrial environments supported by lubrication technologies from Spanjaard and high-performance oil systems like Lubtex.

Choose the right viscosity grade to match your operating conditions and improve long-term gear reliability with confidence.
