Miniature ballscrews are manufactured by the highly economical cold-rolling process which offers both significant cost savings but also maintains a precision previously often only available with machine-ground screws. Miniature ballscrews are complemented by a range of single steel nuts produced in a special cost-cutting process. Miniature ballscrews offers all the advantages of the inherent ball screw design: – high efficiency, i.e. – low power input – low self-heating – low frictional, stick-slip-free running – maximum wear resistance, i.e. very good repetition accuracy with a constant positioning precision. – high reliability and durability. Materials Screws as well as nuts are made of hardened steel. Stainless steel upon request (please ask for load rates). Operating temperatures Regular applications: 0 to + 80 °C. Ball return Nuts feature single-thread ball returns or tube type ball returns, both fully integrated into the nut shape.
