Description
The Microstage 42 product line was designed with performance and price in mind. The basic housing of the Microstage 42 is a precision machined extrusion. The motion mechanism is comprised of a precision lead screw, with an antibacklash nut, combined with a precision profile linear bearing, A NEMA size 17 motor (42mm square) step motor and antibacklash coupling are standard, and are included in the base price. End plate bearing housings, motor mounts are universal throughout the product line.
Options have been designed with economy in mind as well. Adjustable, optical, end of travel limits are mounted on an extrusion attached to the outside of the stage, with a flag mounted on the moving carriage. The Microstage 42 is designed for an optional ball screw for those customers that prefer a ball screw to a lead screw.
For multiaxis application, USAutomation offers standard XY, XZ, XYZ, and Gantry mounting brackets as standard options. Cable carriers, connectors and other modification are available upon request. If a special configuration is needed, we encourage such opportunities.
