Vacuum Pumps
Operating in a high or ultra-vacuum environment presents a number of challenges for bearings, which are essential in achieving the high speeds and reliability demanded by turbomolecular and high speed dry pumps.
Working in a pressure range of up to 1×10-10 mbar with minimal lubrication and potential high temperatures of above 500˚C (932˚F), performance, reliability and a long lifetime must be ensured. DSN bearings are engineered to achieve this, each and every time.
DSN vacuum pump bearings offer:
Manufacture from high performance materials to ensure compatibility with high-temperature environments and high speed running.
Ceramic (silicon nitride) balls to permit a significant increase in speed with less wear.
Materials offering low outgassing rates.
Various coatings (including gold, silver and MoS2) to act as dry lubrication.
Direct lubrication design features.
Super finished surfaces and optimised surface geometry.
Minimal maintenance and long life properties.
Fully shielded and sealed versions of all bearings to prevent contamination ingress and contain lubrication.
ABEC 7/9 (ISO P4/P2) tolerance standards for the highest precision.
Typical vacuum applications include:
Semiconductor production.
Space environment equipment.
Medical equipment.
Chemical analysis.
Helium leak detectors.
