The new Enidine HCL elastomeric bearings are designed to give rotorcraft designers precise, engineered control over stiffness and damping, reducing in-flight vibration and allowing for flexibility in blade and rotor assembly. The bearings support high loads and blade motion without lubrication while decreasing rotorcraft maintenance costs by reducing bearing replacement intervals because the part is resistant to dust, debris and fluids, ITT says.

Meanwhile, the Enidine Frahm dampers are tuned vibration absorbers used on airframes and rotors to reduce vibration and increase comfort for pilots and passengers. The dampers are tuned to resonate at the same frequency as the rotorcraft components, absorbing and counteracting undesirable vibration through a rotorcraft.

ITT says the devices will help to increase performance, fuel efficiency and longevity of flight-critical components as well as protect cabin interiors from noise and vibration.

ITT will showcase the new products at the upcoming HAI HELI-EXPO 2018 taking place Feb. 27 through March 1 in Las Vegas.
