Non-Captive Stepper Motor Actuators
Our Non-Captive Stepper Motor Actuators bring high-precision linear motion to applications where compactness, flexibility, and system integration are key. Manufactured in Beachwood, Ohio, these actuators feature a translating screw design where the lead screw passes through the motor housing while external components provide the anti-rotation mechanism.

Engineered for Your Application
- A translational lead screw driven by a NEMA-frame stepper motor in sizes from NEMA 8 to NEMA 34, enabling a wide range of diameters, leads, and stroke lengths.
- Efficient, precise motion achieved through matched screw, nut, and motor assemblies that supports low backlash and high repeatability in systems such as inspection equipment, semiconductor tools, medical machinery, and robotics.
- Customizable configuration options including end-machining, screw length, nut style, encoder readiness, and wiring harnesses; all backed by application-engineering support in the U.S. to ensure smooth integration.
Applications & Industry Fit
Non-captive actuators are ideal when your machine already incorporates anti-rotation or guidance mechanisms, and you require a motion system that is compact, efficient, and flexible. These are commonly used in automated testing systems, semiconductor wafer handlers, fluid-dispensing modules, and medical analyzers; where precision, small form-factor, and adaptability matter.
