Bellows-sealed rotary feedthroughsProduct catalog

These bellows-sealed rotary feedthroughs are available with high-precision rotary feedthroughs and compact rotary feedthroughs as a unit and conduction rotational motion from the atmosphere side to the vacuum unit. They can be used in regions up to high vacuums because metal welded bellows are used for isolation between the vacuum and atmosphere.
We offer two types of compact rotary feedthroughs. One type includes a rotational positioning accuracy (at no load) of 2°±0.5°, while the other type includes high-precision rotary feedthroughs with an accuracy of as high as 0.5°.
