Shasta W33 (LGSW33) Linear-Guide Stage

 

The Vertex Shasta W33 (LGSW33) linear-guide stage  offers performance linear positioning in a highly configurable assembly. This 33-mm–high actuator has a 120-mm rail spacing to increase stability. The actuators are available with a variety of leads in both the ball-screw and lead-screw versions. Repeatability ranges from 10 µm to 50 µm. The units are best used with loads that are placed directly on the carriage.
