Vacuum version available
 
 

Precision vertical positioner provides high-precision positioning and smooth travel for loads up to 10 kg. The wedge design, driven by precision rolled leadscrew, converts horizontal motion into vertical. Together with high quality linear bearing guide the system ensures rigid and smooth movement across all range of travel and long lifetime. Precision bearings provide platform stiffness and stability while the screw mechanism assures positioning accuracy. For protection of mechanics, optical limit switches are installed.

Based on specifics of application other stepper motors or servos can be used. Stepper motor can be equipped with linear encoder and brake.
