dryspin® high helix lead screws from dryspin® lead screw technology
 
Lead screws are machine elements used to convert a rotary motion into a linear motion. 
 
The high helix lead screws are part of our dryspin range, which is specially designed for fast and very efficient applications. Thread sizes from DS4x2.4 to DS18x100 are available here.
 
dryspin lead screw technology was designed and patented in 2013 by the drylin lead screw technology development team. Particular emphasis was placed on increasing service life and improving efficiency. The dryspin product portfolio includes high helix lead screws made of stainless steel or aluminium (upon request), which are available in pitches from 2.4mm to 100mm. The high-helix thread geometry is an extension of conventional thread technologies such as metric and trapezoidal threads with numerous benefits. You can find more on this topic in our blog about dryspin® technology.
 
The standard material of the dryspin lead screws is stainless steel 1.4301/AISI 304. Thereby it is 100% corrosion-free and low wear. The lead screws are also available in aluminium. The lead screws offered by igus are generally rolled lead screws. The advantages of this manufacturing process (good surface quality and cost-effective production) are ideally suited to the lubrication-free lead screw nuts made of tribologically optimised polymers.
 
Advantages of the dryspin® high helix lead screws:
► 100% maintenance-free dry running
► Longer service life due to asymmetry
► Higher efficiencies compared to conventional trapezoidal threads
► Quiet and vibration-free operation
► Insensitive to dust and dirt
► 100% corrosion-free
► Not self-locking
► Fast delivery times
 
Other lead screw geometries in the product range of lead screws are:
Trapezoidal thread (DIN 103)
Metric threads (DIN13)
ACME threads (ANSI B1.5 2C)
