The UTM Series linear stages feature an all-steel construction with preloaded linear ball bearing slides to provide high stiffness and thermal stability in a space-saving format. A large variety of DC, stepper, and manual drives, all available with different resolutions, allow selection of a stage that exactly meets your application. Smooth motion is provided by a diamond-corrected lead screw and a matched, precision lapped nut to ensure high position stability with high vertical load capacity. The nut design includes anti-backlash preloading and a sophisticated decoupling system that prevents lead screw eccentricity errors from affecting stage movement. All UTM stages include a center home position switch,supplemented by an index pulse signal from the encoder for precise origin location. The home position may also be set to either end of the stage’s travel via an external switch on the stage body.
