Overview

Overview

Linear Actuator Stepper Motors

Stepper motor linear actuators in NEMA sizes 14 (36mm) to 23 (57 mm) in external and non-captive shaft styles

Extremely compact design

Linear actuator stepper motors deliver long life, high accuracy and unsurpassed repeatability. These compact, low cost 1.8° linear motors are available in three sizes: NEMA 14 (1.4″ / 36 mm sq), NEMA 17 (1.7″ / 42 mm sq.) and NEMA 23 (2.3″ / 57 mm sq.).

Great versatility

To meet the needs of a wide range of linear motion applications, two (2) linear actuator styles are available:

  • Non-captive shaft has a threaded shaft that extends through the motor and moves axially as the motor rotates
  • External shaft has a rotating screw, integral to the motor’s rotor, that moves the nut axially along the threaded shaft. An anti-backlash nut is available.

Precision lead screws

Precision rolled lead screws deliver maximum life and quiet operation in combination with the linear actuator’s  self-lubricating nut. Lead screws are manufactured from premium grade stainless steel that is non-magnetic, corrosion resistant and available with an optional Teflon® coating.
