Linear stages - Aerotech Inc.

The Pro Series low-cost, side-seal, hard-cover, ball-screw-driven linear stages come in 68 standard models with travels from 50 to 1,500 mm. A wide variety of travels, widths, speeds, and load capabilities are available. The stages’ hard-cover design protects against debris, while side-seals keep dirt and particulates out and protect the bearing surfaces from contamination. An optional brush assembly removes any particles that collect on the hard cover.
Models are available with either a 5, 20, or 25-mm/rev ball screw with a matched brushless rotary servomotor to provide maximum travel speeds up to 1,400 mm/sec. Features include ±6-μm accuracy, ±1-μm bidirectional repeatability, and 0.5-μm resolution (depending on model), ball screw, and encoder. The modular stages can be combined into custom multiaxis solutions (XY, XZ, YZ, XYZ).
