Series 1412 ultra-precision ball screw assembly

Series 1412 refers to a precision ball screw assembly from Steinmeyer, a German maker of ball screws, with the number indicating a 14 mm nominal diameter and 12 mm lead in the common naming scheme. Steinmeyer produces ground and rolled screws with tight lead accuracy grades, preload options and low friction ball circulation, and many assemblies are supplied with preloaded nuts to reduce backlash and increase stiffness. Ultra-precision grades are used where positioning accuracy and thermal stability matter, with options such as cooled shafts, special end machining and corrosion-resistant materials. Nut styles include flanged and cylindrical forms, and the end bearings are normally machined to customer drawings. Typical applications include machine tools, semiconductor equipment, measuring machines, optical and inspection systems, and precision positioning stages.
