The NEMA 14 (35mm) hybrid ball screw stepper motor combines a powerful 2-phase 1.8° stepper motor with a precision ball screw assembly, delivering efficient linear motion in a 35mm frame size. The ball screw mechanism utilizes recirculating steel balls to achieve up to 90% efficiency with minimal friction and near-zero backlash, providing superior positioning accuracy and repeatability over traditional lead screw designs. With thrust capacity up to 610N, this linear actuator is designed for demanding precision automation applications.
Key Distinction: This is a ball screw linear actuator — offering higher efficiency, longer life, and better positioning accuracy than lead screw (ACME/T-type) alternatives, at a higher cost point.
