Castrol Optigear Synthetic CT 320 is a synthetic polyalphaolefin (PAO) gear oil designed to perform in the most challenging of applications, especially those found in the wind industry. Its high viscosity index coupled with advanced gear oil additives make it an ideal lubricant for gear boxes where large changes in temperature and humidity can not be controlled.
Advantages When compared to more conventional gear oils Optigear Synthetic CT 320 has the following advantages:
Maximum protection of gears against wear and shock loading, including protection against micro-pitting
Excellent thermal and oxidative stability provides reliable operation and extended operating life when compared to
mineral oil based products
High corrosion protection for gears
Inherently high viscosity index makes the product suitable for operations over a wide temperature range
Good water separation and demulsification characteristics reduce down time through prolonged lubricant life and
increased equipment reliability.
PAO base provides good compatibility with seals, paints, and mineral oil based lubricants
