Product Details

Model: Nema 17 Hybrid Stepper Motor Captive Linear Actuator With Threaded Drive Screw (1.8 degree)

Top selling designs deliver high performance, opening avenues for equipment designers who previously settled for products with inferior performance and endurance.

This Series is available in a wide variety of resolutions - from 0.00006-in. (0.001524 mm) per step to 0.00192-in. (0.048768 mm) per step, and delivers thrust of up to 50 lbs. (222N), or speeds exceeding 3 inches (7.62 cm) per second 

1. It has a threaded drive screwheld mostly inside the motor body which connected to a spline.
2. It has a built in anti-rotation though the use of a spline shaft that allows it to extend and retact as a unit with no requirements for additional anti-rotation.
3. The captive actuator is designed for shorter strokes up to about three inches, the basic design is least tolerant of system misalignment and is the most protective actuator style, beacuse it is self contained. The captive has the longest basic body style.
