Description
Product Description
CASTROL ALPHASYN™ EP 1500 is a premium fully synthetic industrial gear oil based on Polyalphaolefin (PAO) synthetic fluids with sulphur/phosphorus Extreme Pressure (EP) additive technology. It is specially developed for heavy-duty enclosed gear systems, dragline swing boxes, mining equipment, quarry machinery, large industrial gearboxes, and heavily loaded bearings operating under severe conditions. The advanced formulation provides excellent thermal stability, high load-carrying capacity, superior wear protection, reduced friction losses, and extended equipment service life.
The combination of high viscosity index PAO base oil and EP additive technology allows ALPHASYN EP 1500 to maintain strong lubricant film strength at elevated temperatures while providing reliable protection against shock loads, gear tooth wear, and micropitting damage.
Features and Benefits
Fully Synthetic PAO Technology
The PAO synthetic base fluid provides:
- Excellent thermal and oxidative stability
- High viscosity index
- Superior performance over a wide temperature range
- Reduced friction and energy losses
- Extended oil drain intervals compared with mineral gear oils
Outstanding Extreme Pressure (EP) Performance
Advanced sulphur/phosphorus EP additives provide protection against:
- Heavy gear loading
- Shock loads
- Gear tooth wear
- Scuffing
- Surface fatigue
Ideal for severe-duty industrial gear applications.
Excellent Micropitting Protection
Provides enhanced resistance against:
- Grey staining
- Micropitting fatigue
- Gear surface damage
helping extend gearbox reliability and operating life.
