Non-Captive Linear Motor

In a non-captive actuator linear actuator, the lead screw does not have an anti-rotation feature. A non-captive actuator is more straightforward and more compact than a captive linear actuator. The non-captive linear actuators are typically used for applications with a stroke of 30-200mm. The advantage of non-captive linear actuators over external linear actuators is that they allow for greater mounting coaxial tolerance errors. It is widely used in valve controls, inspection equipment, test equipment, semiconductor applications, fluid dispensing systems, blood analyzers, and surveillance video camera focusing mechanisms.
