Product Listing

UHV Series

Compact high-temperature linear motion feedthroughs have the smallest atmosphere side envelope and are constructed with high temperature vacuum grade materials. Linear position is measured along a laser etched stainless steel barrel graduated in 20 equally spaced increments. A full revolution of the barrel translates into 1.25mm of linear travel. Air side linear clearance must be considered to accommodate the rising lead screw mechanism. Formed stainless steel bellows, a 1.25mm pitch lead screw design and the use of radial bearings provide this product with excellent durability and performance. All drive mechanism components are located on the atmosphere side of the formed bellows.
