Castrol Alphasyn T 150 Industrial Synthetic Gear Oil


Castrol Alphasyn T 150 industrial synthetic gear oil is a lubricant based on polyalphaolefin (PAO) fluids along with sulphur/phosphorus anti-wear additive technology providing outstanding thermal stability and good load-carrying capacity


The Alphasyn T range has been formulated for use in most types of light to medium-duty enclosed gear systems but should not be used for heavy or shock-loaded systems. Alphasyn T is also suitable for bearings and circulatory systems operating at high temperatures. Alphasyn T is suitable for various applications where lubricating oil is used under high temperatures, e.g. from hydraulic systems through to large, slow-moving gears. All products in the Alphasyn T range have very low pour points and excellent viscosity and temperature characteristics, allowing their use in both low and high-temperature applications.

Castrol Alphasyn T 150 is fully compatible with nitrile, silicone and fluoropolymer seal materials.

Alphasyn T is classified as follows:
DIN Classification is CL

Castrol Alphasyn T 150 meets the requirements of:

  • DIN 51517 Part 2
  • David Brown Type A

Castrol Alphasyn T 150 Lubricant Advantages:

  • Good thermal and oxidative stability provides reliable operation and extended operating life when compared to mineral oil-based products.
  • An inherently high viscosity index (VI) makes the product suitable for operations operating over a wide temperature range.
  • Good anti-wear and load-carrying abilities minimise gear wear and prolong gear tooth life.
  • Reduced downtime through water separation and demulsification characteristics resulting in prolonged lubricant life and increased equipment reliability.
  • PAO-based lubricant that provides good compatibility with seals, paints and mineral oil-based lubricants.
