Accumulated deposits and heat-induced expansion cause mechanical vibration and clearance loss in high-speed vacuum rotors. Addressing these failure modes prevents catastrophic bearing failure and maintains pumping efficiency.

Physical contact and friction during rotation lead to mechanical wear and energy loss. Maintaining a stable non-contact state prevents component degradation and system failure.

High-speed vacuum pump rotors suffer from critical vibration and thermal expansion instabilities. Preventing mechanical contact ensures continuous operation without lubricant contamination or bearing failure.
