The DFU2005 Double Nut Ball Screw Nut is a 1 piece, precision component designed for 20 mm diameter ball screw systems. Its double nut configuration provides preload to reduce backlash, delivering improved stiffness, accuracy, and repeatable motion in linear drive applications. Built for reliable operation in automation and machine tool environments, this nut is suited for upgrades, replacements, or ball screw assemblies. Key benefits Reduces backlash through a double nut preload design, enhancing positioning accuracy and repeatability. Increases stiffness and load handling for stable motion across varying operating conditions. Smooth, reliable performance inherent to ball screw technology, supporting precise linear movement. Simple integration with standard 20 mm ball screw systems, with consistent alignment due to single piece construction. Durable, long term reliability suited for precision automation and manufacturing tasks.
