To reduce axial clearance, one of the most precise solutions is the zero backlash lead screw nut. It consists of several components and adjusts itself to the service life. It is particularly suitable for lead screw drives with high helix threads for quick adjustment of small loads. The zero-backlash lead screw nut is available in six new sizes:
Reduce your design time and streamline your lead screw technology procurement process.
Six different types of lead screw nut made of seven different materials with individual specifications are available. Suitable lead screws are available in high helix, trapezoidal and metric threads and in stainless steel, steel and aluminium. We have clearly presented all dimensions for you.

The dryspin high helix thread technology was developed by igus in 2013 and offers numerous advantages compared to conventional high helix threads. Due to the flat thread angle, it efficiently converts the force introduced into a translational movement. With specifications and geometries matched to the plastic nut and spindles, dryspin 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 proportion (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.
