High-precision SF6-Air Vacuum For determining the quality

Optimal alignment of the rotor with lowest reproducible friction is provided by sealed high-precision ball bearings. Compared to an air bearing, the main advantage is the ability to operate in vacuum. This is a tremendous improvement for high-temperature viscosity measurements in controlled atmospheres.
