The ATS125 is Aerotech's smallest hardcover, side-sealed linear stage. The integral brushless motor reduces the overall footprint of the stage enabling its deployment in space-constrained applications, while the hardcover provides protection from debris created in the manufacturing process. The robust aluminum cover is hard-coated for scratch resistance, and the side seals keep dirt and particulates out of the stage and protect the bearing surfaces from contamination. The vertical orientation of the seals easily deflects debris away from the stage. Top seal designs can collect debris, resulting in the eventual failure and replacement of the sealing mechanism.
