Industry Information

Lead Screws

Lead screws are tools used to convert rotational motion into linear motion. Lead screws consist of a threaded shaft and nut. As the nut moves up and down the shaft, force is exerted linearly on one side of the nut, depending on the direction of the nut's movement.

Lead screws are used in many varieties of equipment to generate controlled, precise lateral movement. They can be used to move large plates in crushing applications, and they can be used for delicate equipment movement. 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. Unlike ballscrews, which make use of rollers to reduce friction and increase efficiency, lead screws involve direct contact between the screw and the nut. Innovations in screw thread design have mitigated the disadvantages that presented themselves because of this inefficiency. Acme screws, for example, are among the most popular lead screw varieties. The special trapezoidal shape of their threads increases their operating lifespan and efficiency. Their design allows them to prevent unwanted backdriving, which is the reverse motion of a nut. Unintended backdriving can be catastrophic, especially in contexts that involve load bearing. Acme screws eliminate this risk because of their thread shape and angle.

The high amount of friction caused by direct contact between the threads and the nut is the main disadvantage of using lead screws compared to other screw varieties in creating linear motion. The higher force requirement to overcome the friction causes a great reduction in working efficiency. However, screw designs like acme screws are comparatively efficient. Lead screws are available in a variety of configurations. Nut materials, lead and thread forms, lubrication types, speed, length and strength are all customizable. Such customizations depend on the screw's intended application; static, dynamic, tension, thrust, compression and all other kinds of loads each require screws designed specifically for their accommodation. Due to the variable conditions of cleanliness, friction and lubrication, the exact operating lifespan of a lead screw cannot always be accurately predicted. However, proper maintenance practices like frequent lubrication, cleaning and general inspections can extend a lead screw's lifespan substantially.
