dryspin trapezoidal lead screw, left-hand thread, two start, C15 steel AISI 1015

Trapezoidal thread lead screws from dryspin lead screw technology
 
Lead screws are machine elements used to convert a rotary motion 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 shapes of the dryspin lead screw technology matched to the polymer nut and trapezoidal lead screw guarantee an even longer service life and efficiency.
 
Advantages of the dryspin trapezoidal thread lead screws:
► 100% maintenance-free dry running
► Quiet and vibration-free operation
► Insensitive to dust and dirt
► 100% corrosion-free
► High efficiency levels
► Cost-effective purchase
► Fast delivery times
 
The cross section of the trapezoidal thread corresponds to an isosceles trapezoid with an angle of 15°. The thread angle is 30°. Compared to the standard thread, the trapezoidal thread lead screw has a larger diameter and a greater pitch. The pitch angle is smaller than the arc tangent for single start trapezoidal lead screws. Thus, self-locking is given. Two-start lead screws, on the other hand, are not self-locking.
