Applied Science | Make vacuum pre-loaded spherical air bearings without special tools @AppliedScience | Uploaded 4 years ago | Updated 1 hour ago
A new technique to make graphite air bearings without precision tooling. I show how to make spherical, cylindrical, and flat bearings that are also vacuum pre-loaded, meaning the bearing is captive.
