no encoder

Helix Linear Technologies' BSA-34-E 16 mm Threaded Tube Return Ball Screw Stepper Motor Actuators without encoder integrate a NEMA 34 bipolar stepper motor with a precision 16 mm diameter ball screw and threaded ball nut for high-torque, accurate open-loop linear motion in demanding heavy-duty applications. Available across multiple lead options with optional 8N end machining for industrial automation, heavy-load robotics, semiconductor, medical imaging, and aerospace actuation systems where open-loop position control is sufficient. U.S.-made.
