The ball screw drive is an assembly that converts rotary motion to linear motion (or vice versa). It consists of a ball screw and a ball nut packaged as an assembly with recirculating balls. The interface between the ball screw and the nut is made by balls which roll in matching ball forms. With rolling elements, the ball screw drive has a low friction coefficient (typically up to 98%). The forces transmitted are distributed over a large number of balls, giving a low relative load per ball comparatively.
Ideal for high-precision, high-load applications, metric and inch ball screws are manufactured to the highest standards to translate rotational motion to linear motion with minimal internal friction.
Not all precision ball screws are created equal. At Thomson, our careful attention to design, quality, materials, manufacturing and application support has set us apart from the competition and created an ideal recipe for success that has lasted for decades.
When standard Thomson ball screws don’t meet your exact specification requirements, our engineering experts can help customize a solution for your application. Whether it’s one or a large quantity, a simple component modification or complex assembly, our custom capabilities can meet your needs and improve your machine’s performance.
Thomson provides extensive online resources to help you no matter where you may be in the purchase decision process:
This video provides an overview of the anatomy and installation of ball screws. It covers the function of ball screws in application design as well as the components of a ball screw assembly and of a ball nut. Also included is a demonstration of the installation of a ball nut onto a screw and the ball bearing insertion process in the event that some bearings fall out during installation.
Any new application requires careful analysis of product performance, life and cost. Especially those that take on larger loads. Learn why you should be considering a high-load ball screw over standard ball screws for your next linear motion application.

How to reload the bearings into a button return ball nut. Often Metric ball nuts are button return ball nuts. But this technique can also be used on tube return ball nuts.
From all the thousands of possible choices, how can you quickly and confidently size and select the optimal ball screw solution for your linear motion application?
How to install a ball nut onto a screw from an arbor.
Because ball screws are available in both inch and metric dimensions, designers sometimes begin the specification process by selecting a product family based on the unit of measure. This decision may prematurely exclude the ideal product for the application and lead to significant losses in time, labor and expense. This article explains how sizing and selection questions centered on performance – instead of product monikers – can lead to more efficient linear motion designs.
Learn MoreRoller screws have been promoted as the only technology of choice for handling large loads when size is a constraint. But in actuality, advances in ball screw technology have now enabled the capability to support high-load applications as well. This is important because a high-load ball screw is typically less than half the cost of a comparable roller screw at equivalent performance points.
Learn MoreUsed in large-scale production applications that involve continuous lifting operations but still require a human touch, collaboration robots (cobots) are gaining popularity. A French cobot maker has developed a solution that uses ball screw and cable actuators instead of gears, setting a new benchmark for cobot efficiency and safety.
