Leadscrews

Leadscrews convert rotary motion into linear motion using a threaded shaft and nut. They have a simple design, making them cost-effective for manual positioning, lifting, and light automation. Unlike ball screws, leadscrews have higher friction and lower efficiency but offer self-locking to prevent back-driving. Common thread types include ACME, trapezoidal, and square threads. They provide reliable motion control for moderate loads and precision.
