Overview

Overview

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 two sizes: 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

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.
