NEMA 14 (35mm) Fixed Through Shaft Type

The NEMA 14 (35mm) fixed through shaft type hybrid stepper motor is a captive linear actuator with a built-in anti-rotation spline mechanism, enabling the lead screw to extend and retract linearly without any rotational movement. This all-in-one design requires no external guide rails or anti-rotation devices — the screw connects directly to the load, simplifying mechanical integration and reducing component count. With optimal stroke lengths up to 50mm, this actuator delivers precise linear positioning for semiconductor handling equipment, medical diagnostic instruments, machine vision inspection systems, and precision automation platforms where high accuracy and compact footprint are essential.

Structure Type: Fixed Through Shaft (Captive) — Screw extends/retracts linearly, does not rotate. Built-in spline prevents rotation. Best for short-stroke, space-constrained applications.
