SW series actuator
* Zero maintenance with repeatable performance for millions of cycles
* Patent-pending 8-pole hollow core motor for optimized unit length, force, speed and performance
* Ball or roller screw in the same body size for application flexibility
* Electroless nickel plated steel hexagon shaft with 25 RMS prevents weld slag adhesion
* 230VAC/325VDC or 460VAC/680VDC skewed windings potted directly into the aluminum extrusion minimizes cogging, keeps unit dimensions as small as possible & enhances thermal transfer
