High-Precision Bearings for Turbomolecular Pumps

Turbomolecular pumps require extremely reliable, high-speed and low-vibration bearings. These pumps operate at tens of thousands of revolutions per minute, often in demanding vacuum environments where stability, precision and long service life are essential. We supply high-quality bearings that meet the strict standards required for turbomolecular pumping systems used in laboratories, semiconductor production, research facilities, vacuum technology and industrial high-vacuum applications.

Why These Bearings Are Critical

Ultra-high rotational speeds – engineered to withstand very high RPM without overheating.
Minimal vibration – ensures stable pump operation and protects sensitive equipment.
Low friction and noise – essential for long-running vacuum systems.
High dimensional accuracy – manufactured in precision grades (P4, P2) for perfect balancing.
Durability under reduced pressure – suitable for both high-vacuum and ultra-high-vacuum systems.

Typical Bearing Types for Turbomolecular Pumps

Angular contact ball bearings (precision grades)
Hybrid ceramic bearings (Si3N4 balls)
High-speed deep groove ball bearings
Custom bearing units for pump manufacturers
