Newport Motorized Linear Rotation StageUSED
Micro Step Drive Stepper Linear stage offers a 250 mm travel range and
combines fast, sub-micron resolution motion in a highly stiff and robust
package. Its extruded aluminum body with Metric threaded holes has been
optimized to avoid bending effects caused by the different thermal
expansion coefficients of the aluminum body and steel rails. The special
U-profile also provides stiffness to the structure while keeping the
mass low. A preloaded, backlash-free ballscrew provides rapid movements
with fast step and settling times. The screw is accurately profiled to
reduce heating to a minimum and extend the life of the stage.
Recirculating ball bearing slides ensure accurate linear motion and
eliminate ball cage migration found on typical linear ball bearings or
crossed roller bearings. Position measurements are read with a 4000
pts/rev. encoder located directly on the screw, avoiding screw/motor
coupling errors. An upper rigid cover prevents damage to the drive train
and protects it from dust, debris and other pollutants. ILS Series
stages also feature an origin located at the center of travel for
repeatable initialization, limit switches to prevent over travel, and
elastomeric end-of-run dampers for smooth emergency braking.
