Special order examples
While a standard type of magnetic fluid seal has a single-axis rotary mechanism, we can offer a rotary mechanism with two axes or more. Because each shaft is independent, it can rotate by individual rotation speed.
Seal combined with linear bellows
The unit makes expansion / contraction movements towards the direction of the shaft core as its shaft rotates.
This is mainly used for robot arm joints.
With a labyrinth structure
To prevent the entry of dusts and byproducts to the unit, a labyrinth structure is installed on the connecting part on the vacuum side.
With a gas introduction mechanism
A gas introduction path is installed from the inside of housing case to the center of shaft axis. This allows introduction or suction of gases from the shaft end.
A magnetic fluid seal with a pressure-proof structure can increase the pressure resistance to up to 0.99 MPa.
With a purge mechanism
A gas purge hole can be added on the connecting flange edge. Gas purging prevents the entry of vapor deposition components, etc. to the magnetic fluid seal.
