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 thread. The decisive difference between the individual thread types lies in their thread geometry and their respective areas of application.
Each option has specific advantages in terms of self-locking, fine adjustment, operating characteristics and efficiency. We provide a compact overview and explain when each 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 are, for example:
- Automation technology - e.g. in adjustment units and linear systems
- Medical technology - Ideal for sensitive environments due to quiet and lubrication-free operation
- 3D printing and laboratory equipment - Precise positioning in restricted installation space
- Furniture and interior design 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.
igus has set itself the goal of producing in a CO₂-neutral manner by 2025 - including in lead screw technology. The dryspin lead screw nuts are made of wear-resistant high-performance plastic that does not require external lubricants and thus avoids environmental pollution. Thanks to efficient production, plastic lead screws consume up to 50% less energy than comparable metal solutions.
igus also focuses on short distances and reuse for packaging, storage and transport. In this way, igus combines long-lasting, maintenance-free products with a clear commitment to sustainability.

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.
With longer lead screws, resonance effects can occur at higher speeds.
- Higher efficiencies
- Quiet and low-vibration operation
- 30% longer service life due to asymmetry
- Up to 25% less wear
- Greater efficiency
The evaluation of the wear test for the product with the dimensions 10x3 made of stainless steel showed that our dryspin thread Ds10x3 can achieve a wear rate up to 25% lower, a service life up to 25% longer and greater 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, if 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
Unique
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 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.
Service life
If lead screw drives wear out prematurely and lose efficiency under lubrication-free conditions, the dryspin thread geometry provides a targeted solution. Thanks to larger distances between the thread flanks, the proportion of the tribologically optimised igus high-performance polymer can be increased by a factor of 1.3 - for more wear-resistant material in engagement, higher efficiency and a service life that is up to 5 times longer compared to standard geometries.
Quiet operation
If lead screw drives tend to rattle, squeak or vibrate noticeably during operation, the rounded tooth flank geometry of dryspin ensures smooth running. Vibration transmission is significantly minimised by the reduced contact surface between the lead screw nut and the lead screw. The result is vibration-free movement and almost silent operation – even with dynamic movements.
Lubricant-free
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."
