CF Flanged Solid Shaft
Designed to provide rotary motion under high vacuum, these Ferro-Magnetic Fluid Sealed feedthroughs have ConFlat® compatible (CF) mounting flanges. Normal helium leak detectors capable of detecting 1 x 10-11 std cc/sec of Helium flow detect no leakage for CF mounts under static and dynamic testing. Our CF flanged rotary motion feedthroughs routinely operate in the 10-7 Torr range and, when properly prepared and installed, may be used to mid 10-9 Torr using ConFlat compatible (CF) Mounting Flanges.
Baseplate Mount Solid Shaft
These Ferro-Magnetic Fluid sealed rotary feedthroughs are sealed to the baseplate by a fluorocarbon o-ring. The operator mounts these drives to the vacuum chamber by placing them in a suitable smooth-sided port in the chamber wall and using a capture nut. Some models are threaded only part way. They will accommodate various wall thicknesses when used with a sleeve or spacer over the unthreaded portion so that the nut compresses the o-ring.
Please refer to the technical notes about loading, temperature, and other relevant information before specifying a feedthrough.
O-Ring Flanged Solid Shaft
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.
Thread Mount Solid Shaft
These Ferro-Magnetic Fluids sealed rotary feedthroughs are sealed to a flat surface by a fluorocarbon o-ring. The operator mounts these drives to the vacuum chamber by screwing them into a corresponding threaded hole, or on some models by placing them in a suitable smooth-sided port in the chamber wall and using a capture nut. Some models are threaded only part way. They will accommodate various wall thicknesses when used with a sleeve or spacer over the unthreaded portion so that the nut compresses the o-ring.
Please refer to the technical notes about loading, temperature, and other relevant information before specifying a feedthrough.
Features
- A unique magnetic fluid (ferrofluid) is used 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
- Very long life as compared to dynamic o-ring seals
- Low particulate generation for sensitive environments
Applications
- Rotary stages
- Barrels
- Platens
- Planetaries
- Web coater rollers used in thin film deposition and etching processes
Option 1: High Temperature Fluid
- Pending application detail and compatibly verification.
Option 2: Cantilevered Design
- Redesign to locate both bearings on the atmospheric side thus drastically limiting particulate generation.
- Torque rating will be lowered.
Option 3: Maintenance Alert
- Visual or digital signal to indicate when service of the unit is required.
Option 4: Complete Custom Unit
- Custom Body, Shaft Length, Shaft Size, and other mechanical changes possible upon request.
