Product description
Trapezoidal lead screws of the dryspin® lead screw technology
Lead screws are machine elements that are used to convert a rotational movement into a linear motion. 

The Trapezoidal lead screws and lead screw nuts from igus® are based on the principle of lubrication-free linear technology. The specifications and geometries of drylin® lead screw technology, which are tailored to the plastic nut and Trapezoidal lead screw, guarantee even longer service life and efficiency.

Benefits of dryspin® trapezoidal lead screws
► 100% maintenance-free dry operation
► Low-noise and vibration-free operation
► Resistant to dust and dirt
► 100% corrosion-free
► High efficiencies
► Cost-effective purchase

► Fast delivery times

The trapezoidal thread corresponds in cross section to an isosceles trapezoid with an angle of 15°. The thread angle is 30°. Compared to normal threads, the Trapezoidal lead screw has a larger diameter and a larger pitch. The pitch angle is smaller than the arctangent for single start Trapezoidal lead screws. Thus, self-locking is given. Two-start lead screws, on the other hand, are not self-locking.
