Motor lead screws using dryspin lead screw technology

Lead screws are machine elements that are 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 properties and shapes of the dryspin lead screw technology, which are matched to the plastic nut and lead screw, guarantee a longer service life and greater 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 operation with vibration dampening
• Resistance to dust and dirt
• 100% corrosion-free
• High efficiency
• Cost-effective purchase
• Fast delivery times

The trapezoidal thread cross section is an isosceles trapezoid with an angle of 15°. Theflank 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.
