Motor 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 self-lubricating linear technology. The specifications and shapes of the drylin® lead screw technology matched to the polymer nut and trapezoidal lead screw guarantee an even longer service life and efficiency. In the standard range for motor lead screws, you get ready-to-connect thread dimensions from TR08x1.5 to TR12x6P3. Suitable for our drylin® E lead screw stepper motors.

Advantages of drylin® trapezoidal lead screws:
► 100% maintenance-free dry operation
► Quiet and vibration-free operation
► Insensitive to dust and dirt
► 100% corrosion-resistant
► High efficiencies
► Cost-effective procurement
► Fast delivery times

The trapezoidal thread corresponds in cross section to an isosceles trapezoid with an angle of 15°. The thread angle is 30°. The trapezoidal lead screw has a larger diameter and greater pitch than standard threads do. 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 only restrained.
