More hygiene due to lubrication-free lead screw drives
How can unwanted contamination in laboratories be avoided?
Metallic lead screw nuts are still standard in medical technology. However, most of them require regular lubrication and maintenance. Dust and dirt particles can adhere well to the lubrication used. This leads to considerable contamination and significantly higher wear compared to a dry-running system. In addition, the metallic lead screw nut can corrode quickly in damp environments.
The lubrication- and maintenance-free drylin® lead screw technology is used in medical technology and has many convincing advantages. They are absolutely lubrication and maintenance-free and can also be used in corrosive environments without any problems.
How igus® lead screw technology can reduce costs in rehabilitation devices
Metal lead screw nuts are more expensive to purchase than plastic threaded nuts. By replacing your metal lead screw nut with the dryspin® technology with the same connection dimensions, you can save up to 50.9 % on procurement costs. Tests have shown that the wear rate can be reduced by up to 25 % and the service life increased by 30 %.

dryspin® lead screw technology
What to do if there is unwanted axial play?
Our backlash-reducing lead screw nut can help
In addition to the right choice of material, a pretensioning mechanism has proven to be an effective measure for reducing unwanted axial play. There are three variants with pretension for our dryspin® steep threads and trapezoidal threads:
► zero-backlash lead screw nut
► Low clearance lead screw nut
► AB lead screw nut
Tech up
25 % less wear
Our lead screw technology impresses in the test laboratory
The test evaluation of the wear test of the 10x3 dimension made of AISI 304 stainless steel has shown that our dryspin® thread Ds10x3 can achieve up to 25 % less wear rate, up to 25 % more service life and higher efficiency compared to the competition and the trapezoidal thread Tr10x3.
30 % longer service life
Thanks to the unique dryspin® technology
The larger distances between the individual dryspin® threads increase the proportion (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and a higher degree of efficiency are decisive for a service life that is up to 5 times longer than that of conventional steep threads.
100 % lubrication and maintenance-free
Ideally suited for hygiene-sensitive areas
From laboratory equipment and hospital facilities to rehabilitation systems - the lubrication and maintenance-free nature of the screw drives enables them to be used in almost all medical areas.
Thanks to the use of the trioblogically optimised iglidur® high-performance polymers, dust and dirt cannot adhere to the screw drive. And the dryspin® technology is also one step ahead in humid environments: it is 100 % corrosion-free. This guarantees smooth running throughout the entire application. Discover maintenance-free dry operation in the dryspin® lead screw technology online shop.
Low noise & Vibration-free
Important factors when dealing with patients
Medical facilities such as hospitals, operating theatres or laboratories often need to be particularly quiet. Accordingly, the parts installed in the applications have to run quietly. Here too, dryspin® technology has proven to be the perfect alternative to conventional metal screw drives.
The rounded tooth flank geometry reduces the contact surface between the threaded spindle and the lead screw nut. As a result, the dryspin® lead screws run almost silently and vibration-free, even under load. Our thread shop offers a wide range of different shapes and sizes of lead screws.
Reduce costs
50.9 % cost savings
Medical applications must fulfil high requirements, such as cleanroom suitability, media resistance, etc. The costs for the small parts required are correspondingly high.
The dryspin® technology impresses in a cost comparison. Not only does it stand out from its metallic counterpart due to its numerous technical advantages, it is also 50.9 % cheaper.
