The new dimensions of the dryspin® preload lead screw nut

For 6.35 and 10 diameter size threads
The new preload 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 preload principle from SHT-PL. Typical areas of application include 3D printers and medical technology for example. The preload lead screw nuts are available in four new thread sizes:
► DS6.35X1
► DS10X2
► DS10X3
► DS10X12

Reduce design time and optimise the procurement process for your lead screw technology.

Tech up

New dimension range for 6.35 and 10 diameter size with patented dryspin® lead screw technology
Consistent minimum axial clearance for high positioning accuracy
Proven preload principle from SHT-PL
Ideally suited for 3D printing

Cost down

100% lubrication-free and maintenance-free
No maintenance work due to self-adjusting axial clearance from both sides
More cost effective compared to zero-backlash lead screw nut due to fewer components

Proof

Less axial clearance due to lead screw nut spring pre-load

Sustainability

No grease or oil in the lead screw drive
Long-lasting use due to patented asymmetry

More clearance-reduced lead screw nuts

To reduce unwanted axial clearance
In addition to the preload lead screw nut, other lead screw nuts with a preload mechanism have proven to be an effective measure to reduce the unwanted axial clearance. For our dryspin® high helix threads and trapezoidal threads, there are three versions with pretension: Zero-Backlash, Low-Clearance and AB lead screw nut.

We have summarised all the advantages and necessary installation instructions for our clearance-reduced lead screw nuts for you in a nutshell.

Higher efficiency, longer service life

This is what dryspin® technology can do
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.
