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.
I am familiar with the igus drylin lead screw technology and know the required specifications of my product.
I would like to configure my lead screw drive online or download CAD data, catalogues, etc.
I am not sure which drylin® lead screw technology products to choose and need more information.
I would like to learn more about the various fields of application and the use of dryspin lead screw technology.

Lead screws are machine elements and are ideally suited for converting rotational movement into linear movement (for a door drive, for example). There are many different thread shapes and thread types, all of which have their own special features. But what exactly is the difference between the European trapezoidal threads and the American ACME threads? Aren't they the same?
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.
The JGRM lead screw nut stands out clearly from its metallic equivalent:
►100% free of lubrication, maintenance and corrosion
► Up to 34.4% lighter weight and 61.5% lower acquisition costs
► Quiet and vibration-free operation
The new type of the DST-JGRM series has an injection-mould-optimised design, the robust alternative to a flange lead screw nut. The special design allows easy installation and, in particular, the absorption of radial loads. In combination with a stainless steel plate, it can withstand axial loads of up to 6MPa.
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.
