With the drylin^® lead screw technology

Lead screw drives are machine elements that convert rotary movement into linear motion (transmission threads). igus high helix and trapezoidal lead screws are available in three different lead screw materials (steel, stainless steel and aluminium) and in combination with more than seven different lead screw nut materials. Friction-optimised iglidur materials allow quick, simple configuration and ordering of applications that require no lubrication or maintenance.

The asymmetrical threads of the dryspin technology developed by igus increase service life, and its flat flank angle increases efficiency. The geometry of the lead screw nut suitable for the threaded rod is variable, even in the standard item. There are geometries for everything from cylindrical designs to designs with flanges or spanner flats to clearance-reducing lead screw nuts, such as zero-backlash, low-clearance, and anti-backlash lead screw nuts.

The dryspin® technology

High efficiency and low wear

The patented dryspin high helix thread technology was developed by us in 2015 and offers numerous advantages compared to conventional high helix threads. Due to the flat thread angle, they convert the exerted power efficiently into a translational movement. With properties and shapes matching the plastic nut and lead screw, dryspin thereby provides an even longer service life and more efficiency for high helix threads. Due to the rounded tooth geometry, the contact area between lead screw and nut is reduced, and the lead systems operate quietly and without vibration under load.
 
The larger spaces between the individual dryspin threads result in a higher share (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to five times longer compared to conventional high helix threads.
