Universal's high-quality lead screw assemblies meet your most demanding micro positioning applications. Specify lead accuracies of 10 microinches per turn and 25 microinches per inch, the best in the industry!
Unmatched lead accuracies minimize thread helix nonlinearity, eliminating the "once around" banding problems common in high-performance graphic imaging equipment such as color scanners, recorders, and printers. Other application examples include photomask inspection, semiconductor manufacturing and prepress imaging.
