The new pre-load lead screw nut convinces with minimal axial clearance and highest positioning accuracy. It is the cost-effective alternative to the zero backlash and ideally suited for small pitches. This is the proven pre-load principle from SHT-PL. Typical applications include 3D printers.
The pre-load lead screw nuts are available in three different thread sizes:

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.
