Rotary Feedthroughs / Elastomer Sealed Shaft

The ORR series 'elastomer sealed' rotary motion feedthroughs is an economical alternative to our bellows sealed devices. They are ideally suited for less critical applications in the high vacuum regime.

They are constructed of black-anodized aluminum and stainless steel. In vacuum bearings are dry-film lubricated with tungsten-disulfide, while air side bearings are lubricated with high-temperature Krytox® lubricant. The rotation shaft is sealed with a Viton® elastomer O-ring located at end opposite vacuum mounting flange.

Standard rotary feedthroughs are fitted with a manual actuator, and are also available with an air-side shaft extension for added drive flexibility.

These rotary feedthroughs are available on Conflat® compatible CF style metal seal or ISO-KF elastomer seal flanges.
