Castrol ALPHASYN EP 150 – Synthetic Industrial Gear Oil
Product Description
Castrol ALPHASYN EP 150 is a premium fully synthetic industrial gear oil formulated with high-quality PAO base stocks and advanced Extreme Pressure (EP) additives. It is designed for enclosed gear systems operating under heavy loads, shock loading, and severe operating conditions.
It provides excellent wear protection, micro-pitting resistance, and extended oil service life compared with conventional mineral gear oils.
Key Features & Benefits
• Excellent Extreme Pressure protection for heavy-loaded gears
• Outstanding oxidation and thermal stability for long oil life
• Superior micro-pitting and wear protection
• High load-carrying capacity under shock loads
• Excellent rust and corrosion protection
• Rapid air release and low foaming characteristics
• Wide operating temperature range due to high viscosity index
• Compatible with seals, paints, and mineral oils
Typical Applications
• Enclosed industrial gearboxes
• Heavy-loaded gear drives in mining, cement, steel, and paper industries
• Bearings operating under high loads
• Marine and offshore gear systems
• Industrial drives requiring synthetic ISO VG 150 gear oil
