Other characteristics


These Ferro-Magnetic Fluid sealed rotary drives are designed for high vacuum applications where the chamber port has a flat, polished outer surface suitable for seating an o-ring surrounding a hole through the vacuum wall. Each feedthrough has a fluorocarbon o-ring installed in the flange. These flanges do not correspond to standard vacuum industry flange systems; however, the dimension table provides the information needed to mate to the chamber. Alternatively, we can supply an adapter spool piece to mate any feedthrough to a vacuum flange. Features Use a special magnetic fluid (ferrofluid) in place of an o-ring seal around dynamic parts Fluid hermetically seals the shaft, making a liquid o-ring while a permanent magnet keeps the fluid in place Ferrofluid magnetically held in stages formed by grooves machined into either the shaft or pole pieces Unlike regular o-rings, the ferrofluid o-ring remains intact for years of operation despite the shaft's motion
