Test reports of the dryspin® 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 higher 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.

Wear is an important aspect for components in moving applications. Wear-resistant plastic such as our iglidur® materials are the solution to minimise wear and increase the service life of the components. Thanks to the tribological specification, the iglidur® materials are perfectly suited for all areas of application in which a good coefficient of friction and the lowest possible wear are important. The industry's largest test laboratory extends over 3,800 m², where igus® carries out research, development and extensive test series. All materials are tested for their tribological specifications using various test series so that wear and maintenance intervals can be minimised. They are particularly low-friction and low-wear and ensure lubrication-free and low-maintenance use. iglidur® plastic offer very good tribological specifications and therefore guarantee a longer service life for plastic components.
