Custom Ball Screws

Ball screw customization options

Thomson ball screws excel in applications that call for the “just-right” solution, however, that sometimes requires exploring unique options outside of our standard product offering. Our experienced engineers can assist you in easily customizing ball screws to provide compact, quiet and accurate positioning, improve your machine’s performance, lower your cost, and match the exact requirements of your light-to-medium load applications.

We welcome and encourage requests for specialized products, regardless of quantity or frequency of order. Our custom products range from one-time-only units to high quantity requirements. If cost or design constraints dictate a more integrated package, let our application engineering staff help you simplify your design.
