Lead Screw Example
Precision positioning unit with ground screw thread, double nut with adjusting mechanism for non- backlash and constant torque.
Adjusting thread M14 x 0.5, pitch deviation relative to entire length (224 mm) max. 0.02 mm.

Lead Screw Example

 High-precision positioning unit with gauge accuracy, with hardened steel nut containing one straight and one inclined ground groove, places maximum demands on form, position and dimensional tolerances. Thread M6 x 0.5, pitch deviation max. 0.005 mm/30 mm, concentricity error of the adjusting thread max. 0.005 mm, concentricity error of the nut outside diameter and groove position max. 0.002 mm.
Lead Screw Example Positioning unit with rolled trapezoidal thread and brass nut, places high demands on straightness and concentricity.
Thread Tr 10 x 2, concentricity error max. 0.02 mm, pitch deviation max. 0.03 mm/300 mm.
Lead Screw Example Precision positioning unit with differential thread, partially hardened screw with two measuring threads, steel nuts, places high demands on sequential precision and geometry. Differential thread M8 x 0.5/ M10 x 0.6, pitch deviation max. 0.001 mm/10 mm, axial backlash 0,015 mm max. at 50 N load, concentricity error of the nut outside diameter max. 0.002 mm.

Lead Screw Example

 Precision positioning unit with partially galvanically treated screw. Bore on the face side, brass shank with adjustable backlash by means of conical tensioning thread. Adjusting thread M7 x 0.25, concentricity error of the screw face bore max. 0.05 mm, angularity of the spindle outside diameter to the fixing flange max. 0.03 mm.
Lead Screw Example Special positioning unit for use in the aviation industry, screw and nut in special materials bearing a certificate, with optimized weight characteristics and for use under extreme environmental conditions. Adjusting screw ACME 0.250-16-4 G Axial backlash max. 0.08 mm, material in accordance with MIL-S- 7920 / QQ-M-8O, peak to valley height on the shank 0.8 µm, surface treated in accordance with MIL-S- 5002. Fixing thread UNF 0.250-28.
