It looks promising from here.
PS: Maybe never discussed why it works well >>> The varying sizes, locations, and heights of those little convex surface bumps integrates over the relatively large footprint of the Teflon. This almost entirely prevents (the integrated) "stiction" where the coefficient of static and sliding friction differ significantly for smooth contact but far far less for structured contact comprising myriad discrete convex quadratic ~islands~, randomly distributed in lateral location, size, and height. The arcane theory regarding the details is interesting and pretty well understood. The complimentary material (the Teflon) must be compressible and tolerate wear gracefully... indeed it must wear, of the whole principle falls apart. So, when you see a wee bit of Teflon powder around your bearings --- that's actually indication that it's working as intended and provides that ~buttery smooth~ motion that we all celebrate. Tom
