Thomson Industries Motorized Lead Screws
These precision-engineered motorized lead screws combine a hybrid stepper motor and lead screw in one. The screws come in two motor configurations: rotating screw (RS) and rotating nut (RN) and in standard and high-precision variants with a range of standard options. NEMA frame sizes between 11 and 23 can be selected with various lead screws available in metric and imperial sizes. Stepper resolutions range from 0.00016 in (0.00398 mm) to 0.005 in (0.127 mm). The NEMA 23 variant delivers a maximum axial thrust of 200 lb (890 N).
