More hygiene due to lubrication-free lead screw drives

Contamination in laboratories

How can unwanted contaminations be avoided in laboratories?

In medical technology, metallic lead screw nuts continue to be the norm. However, they mostly require frequent maintenance and lubrication. In this process, dust and dirt particles can easily stick to the used lubrication. This leads to considerable contamination and a significantly higher wear compared to a system that works in dry operation. Furthermore, the metallic lead screw nuts can corrode quickly in humid environments.
The lubrication-free and maintenance-free drylin lead screw technology is used in medical technology and convinces due to its many advantages.  It is absolutely free from lubrication and maintenance and can also be used in corrosive environments without problems.  

How igus lead screw technology can reduce costs in rehabilitation equipment

Metal lead screw nuts are more expensive than their plastic counterparts. If you replace your metal lead screw nuts with dryspin technology, with the same connection sizes, you can save up to 50.9% acquisition costs. Tests have revealed that the wear rate is reduced by up to 25% and service life increased by 30%.

What should you do with unwanted axial clearance?

Our lead screw nuts reduce clearance

To reduce the unwanted axial clearance, in addition to the correct choice of material, a pretension mechanism has proven to be an effective measure. For our dryspin® high helix threads and trapezoidal threads there are three versions with pretension:
 ► Zero-backlash lead screw nuts
  ► Low-clearance lead screw nuts
  ► AB lead screw nuts

25 % less wear

Our lead screw technology convinces in the test laboratory

The evaluation of the wear test for the product with the dimensions 10x3 made of stainless steel 1.4301 showed that our dryspin thread Ds10x3 can achieve an up to 25% lower wear rate, an up to 25% longer service life and greater efficiency compared to the competition and the trapezoidal thread Tr10x3.

30% longer service life

Thanks to the unique dryspin technology

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.

100% lubrication-free and maintenance-free

Ideally suited for areas sensitive to hygiene

From laboratory equipment and hospital facilities to rehabilitation systems - the freedom from lubrication and maintenance of the lead screw drives enables use in almost all medical areas.By using the tribologically optimised iglidur high-performance polymers, dust and dirt cannot sick to the lead screw drive. The dryspin technology is also one step ahead in humid environments: it is 100% corrosion-free. Therefore, a smooth operation is guaranteed throughout the entire application. Discover maintenance-free dry operation in the dryspin lead screw technology online shop.

Quiet, & vibration-free

Important factors when dealing with patients

In medical facilities, such as hospitals, operating rooms or laboratories, it often has to be particularly quiet. Hence, the components incorporated in the applications have to run quietly. Here too, dryspin technology has proven itself as the perfect alternative to conventional metal lead screw drives. Due to the rounded tooth geometry, the contact area between lead screw and nut is reduced. This means that the dryspin lead screw drives operate almost silently without vibrations even under high loads. Our online shop offers lead screw drives in a variety of different shapes and sizes.  
Quiet operation with vibration dampening

50.9% lower costs

Medical applications have to meet high requirements, such as cleanroom compatibility, media resistance etc. Therefore, costs for the required small parts are high.
dryspin technology convinces in any comparison of prices. It not only distinguishes itself due to its several technical advantages over its metallic counterpart, but is also 50.9% more cost-effective.
