Differential thermal expansion between high-speed rotors and stators causes axial displacement and bearing failure. Maintaining precise clearances prevents mechanical interference and vacuum seal degradation.

Suboptimal geometry and gas flow management in high-vacuum stages lead to insufficient pressure ratios. Improving compression efficiency reduces backflow and enhances ultimate vacuum performance.

Inconsistent axial positioning leads to mechanical contact and component wear in high-speed systems. Precise contactless stabilization prevents catastrophic failure and energy loss.

Unstable oscillations and resonance during initial acceleration damage sensitive vacuum components. Mitigating these forces prevents mechanical fatigue and ensures system longevity.
