The dryspin lead screw technology at a glance
FAQ lead screw technology: Frequently asked questions
The dryspin lead screw technology is available in five different thread types: trapezoidal thread, high helix thread, sliding thread, ACME thread and metric threads. The decisive difference between the individual thread types lies in their thread geometry and the respective areas of application.
Each variant has specific advantages in terms of self-locking, fine adjustment, running behaviour and efficiency. We provide a compact overview and show when which lead screw is the best choice.
The dryspin lead screw technology is used wherever efficient, quiet and maintenance-free linear movements are required. Typical application areas include:
- Automation technology - e.g. in adjustment units and linear systems
- Medical technology - ideal for sensitive environments thanks to quiet and lubrication-free operation
- 3D printing and laboratory equipment - precise positioning in installation spaces
- Furniture and furnishing technology - for height-adjustable tables or actuators
In addition, dryspin is represented in many other sectors, such as automotive, railway technology, construction machinery, boats, camera technology, food industry, aerospace, packaging industry, etc.
👉 To all fields of application of dryspin lead screw technology
igus is pursuing the goal of CO₂-neutral production by 2025 - also in lead screw technology. The dryspin lead screw nuts are made of wear-resistant high-performance plastics that do not require external lubricants and therefore avoid environmental pollution. Thanks to efficient production, plastic lead screws consume up to 50% less energy than comparable metal solutions.
igus also favours short distances and reuse when it comes to packaging, storage and transport. In this way, igus combines durable, maintenance-free products with a clear sustainability claim.

The maximum recommended lengths for lead screws are generally between 500mm and 3000mm. The ideal length depends on various factors, such as the lead screw diameter, the application speed, the load and the installation position.
Longer lead screws can lead to resonance effects at higher speeds.
- Higher efficiency
- Quiet and low-vibration operation
- 30% longer service life due to asymmetry
- Up to 25% less wear
- Higher efficiency
The test evaluation of the wear test of the 10x3 stainless steel dimension has shown that our dryspin thread Ds10x3 can achieve up to 25% less wear rate, up to 25% longer service life and higher efficiency compared to the competition and the trapezoidal thread Tr10x3.
The lead screws are available in the following materials:
- Stainless steel 1.304 for high corrosion resistance
- C15 steel as a cost-effective alternative
- Aluminium when a non-magnetic material is required
The lead screw nuts are available in various igus high-performance plastics, including:
- iglidur J - our most widely used material with very good all-round performance
- iglidur J4 - our most cost-effective solution
- iglidur J350 - for applications with high temperatures up to 180°C (350°F)
- iglidur A180 - FDA-compliant, suitable for use in the food industry
- iglidur R - with particularly good vibration dampening
- iglidur W300 - for high static loads and simple manual adjustments
- iglidur E7 - for light loads at very high travel speeds

The DST thread geometry
2013
The patented 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 linear movement. With specifications and geometries matched to the plastic nut and lead screws, dryspin provides an even longer service life and more efficiency for high helix threads.
USP1
Due to the larger distances between the individual dryspin thread turns, the thread perfectly matches the specifications of the lubrication-free igus high performance polymers. The proportion of the tribologically optimised polymer in the thread turns can be enhanced by a factor of 1.3 for all sizes. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to five times longer compared to standard thread geometries.
USP2
Due to the rounded tooth geometry, the contact surface between the lead screw nut and the lead screw is reduced. This is due to the fact that the greater the contact of two surfaces moving against one another, the more vibrations are transmitted, which can be perceived as a rattle or squeak. The rounded teeth minimise this effect and the thread moves vibration-free and virtually noise-free.
USP3
Our lead screw systems are developed for maintenance-free dry operation. Basically, you should not compare a lubricated lead screw system one-to-one with a dry-operating system. Due to the external lubrication, the coefficient of friction is lower compared to a dry-operating lead screw system. However, the lubricant also causes a high maintenance effort and additional costs that are often not accounted for.
Application examples
"With its lead screw technology, igus fulfilled all our requirements in terms of validation. One of our customers' key requirements during development was an improved service life. We applied twelve million load cycles to the lead screw assembly of the HLU LE-X (E) and it held. That convinced us. In addition, igus provided us with calculations and the relevant values throughout."
Erik Stratmann
Product Manager HAWE
"The use of dryspin thread technology has significantly improved the entire behaviour of the drive, from the feel and sound volume to the extremely clean and quiet running behaviour."
Thomas Brunner
Head of Mechanical Engineering BRUNNER Elektronik
"We have not considered alternative bearing products. There was direct co-operation with representatives from igus. It worked very well and we are very satisfied with the form of co-operation and its results."
Marta Szymanowska
COO Aether Biomedical
The decision to rely on igus® is based not only on the excellent products, but also on the high level of commitment. The people in charge at igus® were always very committed, interested, customer-oriented, and ready to try out new things, constantly trying to find a solution together with us.
