Shasta 25 (LGS25) Linear-Guide Stage

Shasta 25 linear guide stage

The Vertex Shasta 25 (LGS25) linear-guide stage offers performance linear positioning in a highly configurable assembly. This 25-mm-high actuator is available with both recirculating ball linear guides for high speeds and duty cycles, and lead screws for less demanding applications.

Our Shasta 25 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.
