dryspin DST high helix lead screw made of stainless steel | left-hand thread

dryspin high helix lead screw from dryspin lead screw technology
 
Lead screws are machine elements that are 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 efficient applications. Thread sizes from DS4x2.4 to DS18x100 are available here.
 
The dryspin lead screw technology was designed and patented in 2015 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. 
 
The standard material of the dryspin lead screws is stainless steel 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 from tribologically optimised plastics.
 
Advantages of the dryspin high helix lead screws:
► 100% maintenance-free dry operation
► Longer service life due to asymmetry
► Higher efficiency compared to conventional trapezoidal threads
► Low-noise and vibration-free running
► Insensitive to dust and dirt
► 100% corrosion-free
► Not self-locking
► Fast delivery times
 
Other thread geometries in the lead screw product range are:
Trapezoidal thread (DIN 103)
Metric thread (DIN13)
ACME thread (ANSI B1.5 2C)
