Aeriol ThixOSYN Aviation Grease

Aeriol ThixO SYN Aviation Grease is a specialty lubricant designed for specific aviation applications including helicopter rotor hub, trunnion and pitch horn bearing assemblies, swashplate bearing and tail rotor trunnion and pitch assemblies for the Bell 206A/B, L, L1, L3, L4 and TH-67 series.

This high performance fully synthetic grease combines the unique properties of a PAO synthetic base oil and advanced EP/AW chemistry with the unique properties of an over-based calcium sulfonate thickener. This special formula provides excellent performance in all aviation applications and long-lasting protection for aircraft components.

The low oil separation rate of Aeriol ThixO SYN Aviation Grease facilitates the use of a high index low viscosity base oil over traditional grease formulations reducing starting and running torque. Advanced EP/AW chemistry provides superior high load and extreme pressure protection to over 1.4 GPa without the use of solid lubricants such as molybdenum compounds.
