 | Do you have a need for high precision motion control?
C-Flex pivots are used in applications where there is a need for high-precision motion control, working indefinitely and requiring no maintenance even in extreme conditions such as Vacuum, Very High & Very Low Temperatures and in Ultra-clean Environment without any outgassing.
Typical applications where C-Flex pivot bearings are used include:
- Gimbals - used in a variety of industries ranging from Space, Aerospace, Defense, and others
- Scanning Mirrors - used in Spectroscopy, Sensing, Imaging, LIDAR in a variety of industries
- IR/EO Sensors, Missile Control Nozzles, Accelerometers, Transducers, Governors, and many other applications

 | 84 years ago: How the inventor of air conditioning helped chill NASA's wind tunnels
Global tensions were high in the fall of 1941 as U-boats harassed ships in the Atlantic and German forces pushed deep into the Soviet Union. There was a critical need for the United States to get the National Advisory Committee for Aeronautics' new engine lab in operation. It was especially important to complete its Altitude Wind Tunnel, which could be used to improve the engine performance of high-altitude combat aircraft. By Robert S. Arrighi, NASA Glenn
