KJLC Standard, Hollow Shaft Ferro-Magnetic Fluid Rotary Feedthroughs
Cartridge Mount
Cartridge mounted ferrofluid rotary feedthroughs can replace existing vacuum shafts or spindles which use dynamic o-ring seals (defined as o-ring seals which press against a moving surface). Dynamic o-ring seals frequently cause leaks in processes using vacuum in a manufacturing environment. To remedy this, replace the shaft having the dynamic seal and select a cartridge feedthrough with an OD that slips inside the seal "well" in the process vacuum wall. The static o-ring seals on the cartridge's grooved outer surface do not move, making them far less likely to leak than dynamic o-ring seals.
O-Ring Flange Mount
These ferrofluid rotary feedthroughs are particularly useful for process development applications involving modified shaft details requiring supply of cooling, power, or instrumentation leads to the rotating part. Most models in this group of feedthroughs have o-ring grooved ANSI/ASA compatible flanges.
Please note, should liquid be needed to enter into the application chamber through the hollow drive, it is recommended to use a Deublin water union: in this case, the water feed tubes will rotate along with the 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
Dimensional Drawings
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.
