An economical solution for high-precision designs and applications, lead screws provide compact, quiet linear motion.
Why Thomson Lead Screws?
No other linear motion component combines the speed, accuracy, efficiency, repeatability, quiet operation, lubrication retention, load capacity, and compactness of Thomson lead screws. Our lead nuts are available in a standard threaded or flanged mounting configuration, and anti-backlash nuts provide the best positional repeatability.Customization Options
Not every linear motion design can meet the optimal specifications by using standard lead screws. In these cases, Thomson offers its engineering services to help you customize lead screws to meet your exact requirements and keep your project running smoothly.Where can you get started?

VIDEO: Lead Screw vs. Ball Screw Technology
Jeff Johnson, Thomson Screw Product Engineer, says ball screws and lead screws can sometimes be used in the same applications. Typically, ball screws are used in industry applications that need a lot of load or life while lead screws are used in smaller, lighter duty applications. Lead screws however are highly customizable with the ability to interchange leads, sizes, nut configurations quickly. Cost is usually not the primary consideration when selecting a screw technology. Watch this video to learn the differences.

Why Lead Screws are the Best Fit for Many Linear Motion Applications - and How to Rightly Apply Them
Ball screws are often viewed as the first choice for linear motion applications because the use of recirculating ball bearings provides a high level of efficiency, load capacity and positioning accuracy. However, with careful attention to selection and application, lead screws can deliver efficiency that comes close to ball screws on many applications, high levels of load capacity and very good positioning accuracy

Why Lead Screw Motor Connection Methods Matter
Which motor is right for your lead screw application? A properly integrated lead screw and motor can cut costs, boost performance, simplify maintenance and provide greater prototyping flexibility. Three of the most common approaches include implementing an external shaft coupling; permanently or semi-permanently fusing the lead screw and the motor shaft together; and using detachable connections. This article covers the key considerations when comparing these options.
