dryspin lead screw technology is based on the principle of lubrication-free and maintenance-free linear technology. The specifications and geometries of our lead screw technology, which are matched to the polymer nut and lead screw, guarantee efficiencies of up to 82% and a service life that is up to 30% longer than conventional lead screw drives.
Reduce time spent on design and optimise the procurement process for your lead screw technology. Trapezoidal, high helix and metric threads are available in more than 5,000 variants in the standard product range directly from stock. In addition, you can configure your special solution simply and quickly online.

It is no secret that igus is an advocate of non-lubrication of bearings. Simply put, lubrication is not required for igus products. We often hear the recurring question from customers: "Can I use WD-40 or another lubricant to lubricate my bearing?" Many people think that greasing some products is essential to ensure that they do not seize up and can continue a smooth movement.
Question: hello Stefan, we are getting started today with something a little more special. What is meant by the term "thread size" and what does the designation 10x3 tell us?
Answer: hello. The thread size describes the outer diameter and the pitch of the lead screw, i.e. the basic dimensions of the lead screw. The outer diameter is the distance between the outermost edges of the opposite thread flanks.

There are three variants of our low-clearance lead screw nuts:
► Zero backlash
► Low clearance
► AB lead screw nut
► Four new thread sizes in all designs
► Polymer lead screw nut for heavy-duty applications
► Easy replacement for conventional ball screw drives
► Tech up and Cost down
What is the axial clearance? Which thread directions and important terms do I need to know? And what exactly are the advantages of dryspin technology?
Immerse yourself in the world of lead screw technology and be convinced of the advantages of dryspin technology.
In medical technology, metallic lead screw nuts continue to be the norm. However, they require frequent maintenance and lubrication. Dust and dirt particles adhere and there is significantly higher wear. The dryspin lead screw technology is 100% lubrication-free and maintenance-free and therefore ideally suited for use in hygiene-sensitive areas.

The patented dryspin high helix thread technology was developed by igus 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.

Our lead screw drives require not a drop of lubricating oil. Not only our users, but also the environment profits from this. In addition, our tribologically optimised materials produce less abrasion, as a result of which less energy is needed.
