Motor-Driven UniSlide® MA25 Series
The MA25 Series UniSlide® stage has a body width of 2.5 inches, slider length of 2.5 inches carrying a 15 lbs. horizontal load.
The MA25 Series UniSlide® Linear Stage has a body width of 2.5 inches, slider length of 2.5 inches carrying a 15 lbs. horizontal load. The MA25 can travel up to 20.5″ with the 2.5″ slider/carriage. The MA25 Series UniSlide is available in 7 lead screw pitches. Recommended step rate is 1000/steps per second.
MA25 Series UniSlide® Assemblies are comprised of an aluminum alloy extruded dovetail base with 60 degree opposing V-type ways. An aluminum alloy carriage that runs in the dovetail ways of the base. MA25 lead screws are constrained and supported with pre-loaded Delrin® thrust bearings, which have pre-loaded ball bearings. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.
