Hollow MagiDrive series

The four largest MagiDrive rotary feedthroughs are available in a hollow configuration, terminating with a non-rotating CF flange at the rear. This allows services to be passed through the drive or, alternatively, an additional MagiDrive to be mounted to the rear, providing a secondary axes of rotation. Up to four independent axes of rotation can be provided by combining the MD16, MD35H, MD64H and MD100H MagiDrives. This stacking capability is typically used to provide simple solutions to sophisticated manipulation requirements.

All MagiDrives are:

  • Fail safe – with excess torque a MagiDrive will simply release and lock back onto the next pole avoiding possible costly damage, maintenance and downtime
  • Bakeable to 250°C


MagiDrives benefit from:

  • No bellows, organics or sliding seals
  • True UHV performance
  • High torque
  • Zero backlash under low load and acceleration
  • Magnetic shielding permitting use in magnetically-sensitive environments
