Vacuum pump bearing

Turbomolecular Pumps

These high performance pumps offer a particularly unforgiving environment for bearings. They are used in semiconductor production, chemical analysis and SEM, working in the 10-6 to 10-9mm Bar region.

Under vacuum conditions, the most important requirements for bearings are long, reliable life, reliability and high speed performance. They are expected to exceed 30,000 hours of life with just a single shot of lubricant and operate with very low vibration and noise.

To this end, special surface finish and harmonic limits are applied, while the geometry of the bearing is optimised to combat vibration and noise. Highly reliable, Barden bearings are designed to have infinite fatigue life where possible.
