igus has refined the classic trapezoidal thread, achieving a 30 percent service life extension – a huge increase for a well-established mechanical part. Thanks
to a special geometric interaction between the lead screw nut (which requires no lubrication or maintenance) and the metal lead screw, dryspin technology promises a
long service life, improved efficiencies, reduced wear, and quieter operation. And now, dryspin lead screw technology is available in eight new sizes.

Trapezoidal threads
have been classical mechanical engineering designs for decades. The machine elements convert rotary motion into linear motion – in applications such as window and door
drives, format adjustments in production plants and laboratory technology.

However, almost every classic design has the potential for improvement...
