Description
Castrol Alphasyn™ EP 320
Product Description
Castrol Alphasyn™ EP 320 is a premium full synthetic industrial gear oil formulated with Polyalphaolefin (PAO) base fluids and advanced sulphur-phosphorus Extreme Pressure (EP) additive technology. It is designed for enclosed industrial gear systems operating under heavy loads, shock loads, and severe temperature conditions. The product provides excellent micropitting protection, high load-carrying capacity, and extended service life.
Key Features & Benefits
- Outstanding EP and anti-wear protection
- Excellent resistance to micropitting
- High load-carrying capability for heavily loaded gearboxes
- Exceptional thermal and oxidative stability
- Wide operating temperature range due to high viscosity index
- Excellent water separation characteristics
- Rapid air release and foam control
- Compatible with nitrile, silicone, and fluoropolymer seals
- Long lubricant service life compared with conventional mineral oils.
Typical Applications
- Heavy-duty enclosed industrial gearboxes
- Shock-loaded gear systems
- Steel, mining, cement, paper, and manufacturing industries
- Offshore drilling equipment and top-drive systems
- Gearboxes requiring micropitting protection
- Bearings operating under heavy loads and elevated temperatures.
Specifications & Approvals
Meets or exceeds:
- DIN 51517 Part 3 (CLP)
- AGMA 9005-E02
- AIST 224
