Industry Information

Lead Screws

Lead screws consist of a threaded shaft and nut and create friction through sliding rather than through the rolling friction characteristic of ball screws. The efficiency of lead screws increases with increased lead. Even though they do not use rollers to create movement, they are still placed in the same category as ball screws because of their similar function and capacities. Since lead screws rely on a sliding action, their efficiency is rather low, typically between 25 and 75 percent. The most common type of lead screws is the ACME screw, which creates friction between the ball and the nut.

Lead screws offer smooth operation, accurate positioning over long distances, self-aligning nuts, and long life expectancy. These screws are also favorable to work with due to their lack of noise and high performance. Due to their capability of lifting large loads and handling many different amounts of shock loading, Lead screws are advantageous in managing high shock loads. Perhaps the most appealing characteristic of lead screws, however, is their very low cost.

Lead screws are often used to move tables or other parts of a machine. Lead screws can also offer precision and accuracy for graphic imaging equipment, including color scanners, recorders, and printers. They also provide solutions in other applications, such as in wire bonders, disk drive testers, and linear slide systems.
