Industrial gearboxes in mining, cement plants, and marine vessels face incredibly harsh conditions. The pressure exerted on the gear teeth can be immense, requiring specialized gear oils to prevent metal-to-metal contact and gear pitting.

The Power of EP Additives

Standard oils will squeeze out from between gear teeth under heavy load. That's why industrial gear oils are formulated with Extreme Pressure (EP) additives. These chemicals, often containing sulfur and phosphorus, react with the metal surface under high heat to form a protective sacrificial layer, preventing scuffing and wear.

Viscosity and Temperature

Choosing the right ISO VG grade for gear oil is critical. High-speed, low-load gears require thinner oils (e.g., ISO 68), while slow-moving, heavily loaded gears require thick, viscous oils (e.g., ISO 320 or 460) to maintain a protective film. Proper selection ensures your transmission systems run cooler, quieter, and longer.
