Motion Feedthrough (ST-001)

Product Feature:

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.

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

The ferro-magnetic fluid feedthrough is a high quality, precision engineered device. Each unit is statically and dynamically tested for vacuum integrity, pressure capacity and conformance to mechanical specifications, as part of our continuing quality assurance program.
The ferro-magnetic fluid feedthrough offers unique capabilities in the transmission of mechanical power into a chamber. It operates by trapping a low vapor pressure magnetic fluid in small annular gaps of intense magnetic fields. A pressure differential can be maintained across each stage of trapped ferro-magnetic fluid under both static and dynamic conditions, thus creating a unique zero leakage rotary seal. There are no mechanical contact points other than the bearings, so there is nothing which will wear or require maintenance.
