Linear actuators are stepper motors that incorporate a lead screw as the rotor, which translates motor torque into linear thrust. No maintenance, non-lubricated lead screw nuts ensure long life. NEMA 17 and NEMA 23 frame units are available in multiple screw lengths and leads/pitches; shaft-end journal and rear-shaft for encoder are optional, along with motor power cables in three lengths.
These linear actuators are SureStep NEMA 17 or NEMA 23 frame stepper motors with a stainless-steel lead screw extension of the rotor. In conjunction with the provided screw nut, this actuator translates motor torque into linear thrust. These actuators are often used with undriven linear slides or linear shafts / linear supports to create simple, economical linear motion solutions.
