If you are looking for frictionless, rotary motion that doesn’t move linearly, thrust bushings can be the answer.
These bushings consist of a hollow cylinder of the Porous Media Technology whose outer surface is encased in an aluminum housing. In order to prevent linear motion, a thrust face is added that is also made from porous carbon. These bushings are found in many rotary applications such as turbochargers in high-performance automobiles. Thus these thrust bushings could be the answer, if you’re looking for frictionless, rotary motion that doesn’t move linearly.
