Efficient dryspin® lead screw technology with new pitch

Lubrication-free alternative to ball screws - immediately available in size 5x10

This year as well, we have continued to move forward and have added several sizes to our range of products. The dryspin team works untiringly on the development of new sizes and we are therefore able to present a new thread size in Autumn.
 
All types of lead screw nuts are now available in size 5x10.
► Cylindrical lead screw nuts 
► Flanged lead screw nuts 
► Cylindrical lead screw nuts with spanner flat
► Flanged lead screw nuts with spanner flat
► Cylindrical injection-moulded lead screw nuts
► Injection-moulded lead screw nuts with flange
 

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 properties and shapes matching the polymer 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.
