Description
Pneumatic linear motion feedthroughs provide two-position fast action linear motion. Typical motion applications would include on-off, open-close and in-out motions similar to those of in-vacuum shutters. Linear travel can be shortened or lengthened by turning the adjustment knob located at the top end of the pneumatic actuator. Once adjusted the jam nut locks the knob in place. Linear travel adjustment is from 0" to 1" for one inch travel devices and from 1" to 2" for two inch travel devices. For quick and easy positioning the feedthrough body has been laser etched with linear travel graduation marks in increments of 0.025". A black anodized finish provides high contrast and visibility of the laser etched graduated scale. Pneumatic linear motion feedthroughs are offered in travel lengths of 1" and 2".

They are constructed of high grade vacuum compatible materials. Welded stainless steel bellows and the use of linear bearing shaft supports provide reliability and smooth operation. Pneumatic feedthroughs are available on industry standard Conflat® compatible Del-Seal™ CF metal seal flanges or ISO KF Kwik-Flange™ elastomer seal port mounts.
