Stepper motor linear actuators are stepper motors with a lead screw as the shaft and a lead screw nut as a carriage to create linear motion. These components are maintenance- and lubrication-free. NEMA 17 and 23 frame sizes are available in many screw lengths and pitches.
Stepper motor linear actuators are an all-in-one motor/actuator device consisting of a stepper motor with a lead screw as the rotor. These actuators translate the precise rotational movement of the stepper into a linear motion. Stepper motor linear actuators are maintenance- and lubrication-free and are a great cost-saving option for linear motion applications.

SureStep linear actuators are NEMA 17 or NEMA 23 frame stepper motors with a stainless-steel lead screw extension of the rotor. These actuators are often used with undriven linear slides or linear shafts / linear supports to create simple, economical linear motion solutions.
