Results of a study to examine a unique idea of self-levitating journal bearing are presented in this paper. the idea represents a radical departure from the current bearing technology. it utilisesacoustic levitation, which relies on the sound energy radiated by an object supporting a load. acoustic levitation has been demonstrated to support loads of up to 10 kg. in order to support a load theacoustic wave emitted by the radiating surface must be reflected back towards the radiating surface by the levitating object. the radiation pressure increases as the gap between the source of sound andlevitating object narrows. computer simulation and experimental testing of a prototype device were carried out and provided a conclusive proof of the idea.
