Feedthrought > Magnetic Coupling

feed001.jpg feed002.jpg

Magnetic coupling uses a large number of high flux magnetic fields interlocking inner and outer rotating assemblies through a solid stainless steel enclosure, giving it exceptionally high torsional rigidity. Because Magnetic coupling has no bellows, fluids, or dynamic seals, it features totally leak-tight operation.
The production proven range is supplied with CF UHV flanges and is available in 10 sizes to match the torque requirements of each application. The range includes a unique hollow option, enabling Magnetic couplings to be "stacked" together, offering three independent axes of rotation or possibly used to feed services through such as heating. A number of actuation methods are available, from manually driven units to pneumatic or motorized drives.
Additional options include the use of state-of-theart bearings for ultra-clean applications, such as semiconductor production. The Magnetic couplings are extremely compact, bakeable to 250°C, as standard and up to 450°C for high temperature applications.
Features:

  • True UHV performance
  • Zero-backlash under low load
  • Intrinsically safe for leak-tight applications
  • Bakeable to 250°C
  • Robust, compact construction
