Rotary Drives

The production-proven MagiDrive range of vacuum rotary feedthroughs enables rotation to be transferred into a vacuum system using a stiff high-flux magnetic coupling. With no bellows, fluids or dynamic seals, the MagiDrive range offers reliable and leak-tight UHV operation.

Key features

• Magnetically-coupled, fail-safe design

• Single-piece vacuum enclosure ensures leak-free performance

• Magnetic shielding permits use in magnetically-sensitive environments

• No bellows, organics or sliding seals

• Bakeable to 250ºC (including magnets)

• High torque-to-size ratio

• Zero backlash under low load and acceleration

• Hollow variants allow stacking of concentric drives
