NEMA 8 DWM 20 MM Slide Actuator
The NEMA 8 DWM Series slide actuator is a compact 20 mm wide linear module that combines a stepper motor, lead screw, and guided wide-body slide structure into one ready-to-integrate motion solution.
Designed for OEM systems, the DWM 20 mm series offers flexible lead screw options, multiple stroke selections, and a wide carriage design for precise guided linear motion.
NEMA 8 DWM Wide Slide Actuator Overview
The DWM Series is a guided linear slide actuator platform for compact automation applications that require a motorized linear module with integrated guidance. The NEMA 8 / 20 mm version is suited for small motion axes where space is limited but guided travel, repeatable positioning, and flexible lead screw selection are still required.
