Gear Oils
Castrol Alphasyn HG Range - Synthetic gear lubricants
Alphasyn HG synthetic fluids are polyalphaolefin-based, synthetic high performance lubricants formulated with specially selected additives to offer a range of fluids for use in both gear and bearing applications. The range has been designed to offer specific performance benefits over its conventional mineral oil and synthetic fluid counterparts.
Particularly suitable for applications operating at high temperatures and loadings, Alphasyn HG provides superior performance benefits including excellent thermal and oxidation stability and enhanced load carrying ability as detailed below.
Features and benefits
Alphasyn HG offers a wide range of performance benefits over a conventional mineral lubricant when used in gear and bearingapplications:- Substantially extended lubricant life
- Excellent anti-wear, extreme pressure and load carrying propertiesleading to savings in both maintenance time and costs
- Exceptional lubricity properties increase mechanical efficiency and minimise energy losses
- Proven superior performance across a wide temperature range and in particular at high temperatures
- Excellent thermal and oxidative stability
- Advanced lubricant properties such as viscosity characteristics, low pour point and good air and water separation capabilities
Fully compatible with standard seal, paint and hose material, and with Ortlinghaus multi-plate clutches. Alphasyn HG synthetic fluids pass the standard FZG test (A/8.3/90)with a fail load stage greater than 12 and also the more severe FZG test (A/16.6/140) at fail load stage 10.
Alphasyn HG range meets the IP 135B corrosion and ASTM D2893 oxidation tests. Alphasyn HG meets the following;

Castrol Alphasyn PG Range - Synthetic industrial EP gear oil
The Castrol Alphasyn PG gear oil range of synthetic lubricants are based on poly alkylene glycol (PAG) fluids enhanced with antioxidants, rust inhibitors and Extreme Pressure (EP) additives of high thermal stability.
Alphasyn PG gear oils are primarily intended for use in worm reduction gear boxes, where the low coefficient of friction of the PAG base fluid improves efficiency and consequently reduces power consumption and operating temperatures.
This is particularly important in applications where sliding contact is high. The use of a PAG basestock provides inherently high Viscosity Index (VI) and low pour points making these products suitable for use over a wide temperature range.

Features and benefits
- Low coefficient of friction reduces energy consumption and lowers operating temperatures, this leads to longer oil life
- Good thermal and oxidative stability provides reliable operation and extended operating life when compared to mineral oil based products
- Inherently high VI makes the product suitable for operations operating over a wide temperature range
- High load carrying capacity and good wear protection reduces maintenance
