Lead Screws FAQs

What is a lead screw?
A lead screw is a mechanism consisting of a threaded screw and a mated nut which uses the helical configuration of the threads to actuate linear motion. Lead screw efficiency depends heavily upon the helix angle of the screw thread. For example, a common lead screw, known as the Acme screw, has a 29° thread angle and a thread height which is equal to half of the pitch (pitch being the distance from a specified point on one thread to a corresponding point on the next parallel thread).
What is the difference between a ball screw and a lead screw?
The most significant difference between ball screws and lead screws is the way in which each device carries its load. Ball screws utilize recirculating ball bearings to minimize friction while simultaneously maximizing efficiency. Lead screws, however, depend on low coefficients of friction between sliding surfaces, leaving them far less efficient and accurate than their ball screw counterparts.
How can a lead screw be protected from debris?
If your application involves a dusty or debris-filled environment, you may consider enclosing your lead screw assembly within an extruded aluminum casing or similar apparatus. Additional options include seals, wipers, and the like.
How can I reduce backlash in my lead screw assembly?
Consider a preloaded, anti-backlash nut for your assembly. Nuts can be manufactured to incorporate preload and reduce axial free play.
