Aerotech ATS100-50-U-20P Linear Ball Screw Actuator

The Aerotech ATS100-50-U-20P Linear Ball Screw Actuator is a compact, screw-driven linear stage from Aerotech’s ATS100 family, delivering 50 mm of travel on a precision-ground ball screw with a 2 mm lead and a NEMA23 motor-mount interface. Built with an aluminum body and a box-style frame that houses linear motion guide bearings, it offers high stiffness and repeatable positioning, with payload ratings of 25 kg horizontally and 10 kg vertically for the single-axis system. Top speed is up to 100 mm/s, and calibrated accuracy is ±0.5 µm with bidirectional repeatability of ±0.3 µm; base weight is 1.6 kg (without motor) or 2.7 kg with a motor. The unit is designed for precise, repeatable motion in lab, test, and automation applications and is compatible with Aerotech controllers for turnkey motion control.
