O-Ring Flanged Solid Shaft – KJLC Standard, Ferro-Magnetic Fluid Rotary Feedthroughs


O-Ring Flanged Solid Shaft – KJLC Standard, Ferro-Magnetic Fluid Rotary Feedthroughs

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

Applications

  • Rotary stages
  • Barrels
  • Platens
  • Planetaries
  • Web coater rollers used in thin film deposition and etching processes
