Aerotech (Pittsburgh, PA) has introduced the PRO Series of side-sealed, hard-cover, ball-screw-driven linear stages available in 68 standard models with travels from 50 to 1500 mm. A variety of travels, widths, speeds, and load capabilities is available. The hard-cover design provides protection from debris, and the side seals keep dirt and particulates out of the stage and protect the bearing surfaces from contamination. The tabletop can be outfitted with an optional brush assembly to remove particles collected on the hard cover.
Models are available with either a 5 mm/rev, 20 mm/rev, or 25 mm/rev ball screw with a matched brushless rotary servomotor to provide maximum travel speeds up to 1400 mm/s. Features include ±6 μm accuracy, ±1 μm bidirectional repeatability, and 0.5 μm resolution, depending on the model, ball screw, and encoder. The stages can be combined into custom multi-axis solutions (XY, XZ, YZ, and XYZ), and are outfitted with English or metric bolt-hole pattern tabletops.
