Yes, but not only are the bearings replaced with black ceramic ones (also to be found in jet fighter engines), but the ball cups are also replaced with black ceramic types. Then there are upward facing conical devices-also ceramic I think- with hollowed out apices (looking like a volcano with a crater)....you place another set of ceramic bearinga in the 'crater' and then place the bottom of the equipment on those upward facing bearings, bypassing the feet. And...voila! Vive le difference!
