Aerospace Industry Achievements
Sealing in Space When it comes to space travel, we’re frequent flyers. During Apollo missions, astronauts used tools with our seals in them to sample and store lunar soil. We’ve been helping NASA and others reach for the stars ever since. Making Tracks on Mars As part of the Curiosity Rover mission, our seals traveled >560 million kilometers. Today, they’re still protecting the rover’s drive mechanisms from the harsh Martian environment. Supersonic Shielding At nearly twice the speed of sound, even a little interference can cause big problems. That’s why defense aircraft designers use our Bal Spring® to shield sensitive onboard electronics against EMI.
