Providing Performance with Lead Screws and Ball Screws
Thomson BSA is a leader for ball screws, lead screws (also called power screws), and lead screw nuts for one reason: precision. From manufacturing to design to service, Thomson BSA delivers precision, accuracy, and experience – every time for each lead screw and ball screw.


Lead Screws

Offering smooth, precise, cost effective positioning, our lead screws are the right solution for your application. Thomson BSA precision lead screws are an excellent economical solution for your linear motion requirements. Our precision rolling process ensures accurate positioning to 0.003 in/ft and our PTFE coating process produces assemblies that have less drag torque and last longer.

Ball Screws

When load capacity and efficiency are of paramount importance, Thomson BSA ball screws can get the job done. With standard accuracies available from .010 in/ft to .0003 in/ft, you know you’ll be able to get to the right position also.

Drive Assemblies
Let MSI Tec supply your screw already mounted in bearing supports or also with a NEMA ready motor mount. Why worry about end machining configurations and bearing selection when you can purchase a pre-configured screw assembly to meet your needs.

Stages
Stock Stage assemblies offer a complete mechanical solution for your motion application. These units are ready to attach a load to, complete with linear guides, a ball or lead screw, bearing supports and a NEMA ready motor mount. Simply attach your motor and you’re ready to go.

Round Rail Guides
Every screw needs a good linear guide by its side. Round rail bearings And shafts provide design flexibility, ease of installation and smooth operation. They work well with either our lead screw or ball screw assemblies.
