Motor-Driven UniSlide® MA40 Series
The MA40 Series UniSlide® stage has a body width of 4 inches, slider length of 4 inches carrying a 100 lbs. horizontal load.
The MA40 Series UniSlide stage has a body width of 4 inches, slider length of 4 inches carrying a 100 lbs. horizontal load. The MA40 can travel up to 31″ with the 4″ slider/carriage. The MA40 Series UniSlide is available in 7 lead screw pitches. Recommended step rate is 1000/steps per second. The MA40 is versatile for a variety of applications.
MA40 Series UniSlides 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. Lead screws are constrained and supported with steel thrust bearings and snap ring retainer. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.
