PAX Linear Actuators

Complete systems available including motor, drive, controller, and power supply.

Nook Industries Programmable Linear Actuators are ruggedly designed for continuous duty, larger loads, long service life, and higher speeds. They incorporate a direct drive or toothed belt drive for high mechanical efficiency that allows for a quiet running performance. Programmable actuators are supplied with either a ball screw or acme screw, and either a servo or stepper drive system. 

Optional Ball Screw and Acme Screw drives available

  • Ball screws are used on high-speed applications.
  • Acme screw actuators designed for lower duty cycles where self-locking is desired.

PAX Features
