Efficient dryspin® lead screw technology with new pitches

Your alternative to ball screws - immediately available in five new screw sizes:

With a total of 5 new pitch sizes, igus is adding the dryspin® high helix lead screw product range. For the new thread sizes 6.35x 2.54 LH, 12.7x12.7 as well as 10x3, 16x5 and 20x5, dryspin now offers the suitable high helix lead screws and high helix lead screw nuts.
 
With optimized threads, high efficiency, rounded thread flanks for vibration-free/quiet operation and asymmetrical threads for a long service life, dryspin high helix threads are a cost-effective technological alternative.
 
The new dimensions:

  • DS6.35x2.54 LH
  • DS12.7x12.7
  • DS10x3
  • DS16x10
  • DS20x5

Test result

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 .


Higher efficiency, longer service life

This is what dryspin® technology can do

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 features 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.
