Magnetic Fluid Rotary Feedthroughs can particularly be used as practically wear-resistant Vacuum Rotary
Feedthroughs. Magnetic fluids with extremely low vapour pressure allow operation down into the upper
UHV-range. Because the temperature of the fluid should be kept below 100°C, these products cannot
be used in vacuum systems which are baked.
Benefits of the Technology
- Operation in high vacuum down to 10-9mbar or lower
- Airtight seal, that is virtually hermetic (Leak rate <10-11 mbar l/sec)
- no coupling, the shaft transfers 100% of the torque
- An effective seal at all speeds, from indexing to very high speed
- low friction, low start up and running torque, no "stick-slip" at low speed
- very long lifetime, operation over many years without maintenance possible
