Shasta 33 (LGS33) Linear-Guide Stage

Shasta 33 linear guide stage

The Vertex Shasta 33 (LGS33) linear-guide stage  offers performance linear positioning in a highly configurable assembly. This 33-mm actuator is available with both recirculating-ball linear guides for high speeds and duty cycles, and lead screws for less demanding applications.

Our Shasta 33 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.

DUST COVER OPTION AVAILABLE

    •  
The dust cover options are ideal for dirty/dusty jobs to help deflect containments from directly contacting actuator components.
