Gear Oils

Castrol Alphasyn T 32


Synthetic gear & hydraulic lubricant


The Castrol Alphasyn™ T gear oil range of synthetic lubricants are based on polyalpha-olefin (PAO) fluids and sulphur/
phosphorus antiwear additive technology to provide outstanding thermal stability and good load carrying capacity.


Alphasyn T grades have been formulated for use in most types of light to medium duty enclosed gear systems but should
not be used for heavy / shock loaded systems. Alphasyn T is also suitable for the lubrication of bearings and circulatory
systems operating at high temperatures and various high temperature applications such as in hydraulic systems and for
the lubrication of large, slow moving gears. All products in the Alphasyn T range have very low pour points and excellent
viscosity/temperature characteristics, allowing their use in both low and high temperature applications. The Alphasyn T
range are fully compatible with nitrile, silicone and fluropolymer seal materials.

Alphasyn T is classified as follows:
DIN Classification CL

Alphasyn T grades meet the requirements of:

  • DIN 51517 Part 2
  • David Brown Type A
  • Good thermal and oxidative stability provides reliable operation and extended operating life when compared to
    mineral oil based products.
  • Inherently high viscosity index makes the product suitable for operations operating over a wide temperature range.
  • Good antiwear and load carrying abilities minimises gear wear and prolongs gear tooth life.
  • Good water separation and demulsification characteristics promote reduced down time through prolonged
    lubricant life and increased equipment reliability.
  • PAO base fluid provides good compatibility with seals, paints and mineral oil based lubricants.
