Reduce costs with drylin® lead screw technology

Screw drives are machine elements that convert a rotary motion into a translational motion (motion thread). Steep thread and trapezoidal thread spindles from igus® are available in three different spindle materials (steel, stainless steel and aluminium) and in combination with more than seven different thread nut materials. The friction-optimised iglidur® materials enable lubrication- and maintenance-free use and are quick and easy to configure and order online.

The dryspin® technology developed by igus® achieves a longer service life due to the asymmetry of the threads and increased efficiency due to the flat flank angle. The geometry of the lead screw nut matching the threaded rod is variable even in the standard version. Geometries ranging from a cylindrical design with flange or spanner flats to backlash-reducing lead screw nuts, such as the zero-backlash, low-clearance or anti-backlash lead screw nut, are possible.

The dryspin® technology

High efficiency and low wear
The patented dryspin® steep thread technology was developed by us in 2015 and offers numerous advantages over conventional steep threads. Due to the flat flank angle, they efficiently convert the applied force into a translational movement. With the specifications and geometries matched to the plastic nut and spindle, dryspin® offers even greater service life and efficiency for steep threads. Thanks to the rounded tooth flank geometry, the contact surface between the threaded spindle and lead screw nut is reduced and the threaded systems run almost silently and vibration-free under load.

The larger distances between the individual dryspin® threads increase the proportion (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and a higher degree of efficiency are decisive for a service life that is up to 5 times longer than that of conventional steep threads.

You can also take advantage of our machining service - we manufacture ready-to-install spindles according to your requirements. Use our spindle configurator or send us a drawing. We will then make you an offer.
