This video explains how the Captive Linear Actuator motor operates. An internal nut spins a threaded portion of the shaft. This is one feature that contributes to make the shaft come in and out of the motor. The other feature is the two notches that you see on both sides the shaft. These two notches "captures" the shaft and does not allow the shaft to rotate. Without the notch, it will cause the shaft to rotate in place.

The Anaheim Automation Stepper Linear Actuators product line offers both high quality and cost savings, providing the ideal solution for any application requiring the conversation of rotary motion into linear motion. Available with a linear force range from 40g-cm to 279 lbs, they are available in both captive and non-captive designs. Both four and six-lead wire configurations are available, in addition to multiple customization options.
