High speed bearing assemblies are widely applied in many industries, especially in the airspace and automotive. Design of these assemblies is highly challenging due to some opposed factors affecting their proper functionality. On the one side, there is a condition of rotor-dynamics, which implies the shaft to rotate as stable as possible, retaining its original shape. In regards to this, it was observed that having one elastic and one stiff support, rather than having two stiff supports, provides better dynamic behaviour. On the other side, due to high rotational speed, these assemblies have to be sealed contactlessly, by means of labyrinth, centrifugal or similar types of seals. These seals operate with very small gaps between their rotor and stator. In order to obtain the lowest possible gap in the sealing which allows displacements of the shaft supported by one elastic and one stiff support, a specific design solution is developed. Testing procedure and results, together with design... solutions are presented in this paper.
