Description
MDC rack and pinion linear motion feedthroughs are very similar to push-pull devices, but provide finer control of linear motion. The rack and pinion drive mechanism is still considered quick-action when compared to rotating actuator, linear motion devices. They too are operated by observing the motion process through a vacuum viewport. For quick and easy positioning reference the feedthrough body has been laser etched with linear travel graduation marks in increments of 0.025". A 1-1/4 turn on the handle generates 1 inch of linear travel. An attractive black anodized finish provides high contrast and visibility of the laser etched graduated scale. The actuator can be locked in position by simply tightening the position lock located at the top end of the actuator body. 

Rack and pinion linear motion feedthroughs are offered in travel lengths between 2" and 6". 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. Rack and pinion feedthroughs are available on industry standard Conflat® compatible Del-Seal™ CF metal seal flanges or ISO KF Kwik-Flange™ elastomer seal port mounts.
