Rotary feedthroughs

Our innovative and production-proven MagiDrive range.

This range of vacuum rotary feedthroughs enables rotation to be transferred into a vacuum system via 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

• 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
• No backlash under low load and acceleration
• Hollow variants allow stacking of concentric drives
