Linear stepper motor actuators create motion in a straight line rather than the circular motion provided by conventional stepper motors. They are widely used in medical devices, lab automations and semi-conductor industries. GEMS provides a wide range of capative, non-capative and external type of stepper motor linear actuators and various sizes of ACME thread lead screws and trapezoidal ...
