MDC high temperature linear motion feedthroughs are the perfect solution for linear displacement of in-vacuum samples or devices. They are constructed of 304ss to endure the rigors of high temperature vacuum service. Linear position is measured along a laser etched stainless steel barrel graduated in 0.001" increments. A full revolution of the barrel translates into 0.025" of linear travel. A linear scale on the body is also provided and is marked in both inch and metric units. The inch scale is graduated in increments of 0.025" while the metric scale is graduated in 1mm increments. Welded stainless steel bellows, a 40 pitch lead screw design and the use of linear bearing shaft support provide devices with excellent durability and performance. They are available on industry standard Conflat® compatible Del- Seal™ CF metal seal flanges.
