Let Thomson Help You Make Your Selection!
A vital component for many linear motion systems, roundrail shafting provides a smooth and low drag platform, and is ideal for applications where standard precision is acceptable or lower component costs are critical.
Why Thomson RoundRail Shafting?
With more than 70 years’ experience as one of few suppliers that produces its own precision bearing shafts, Thomson provides best-in-class case hardness and depth, surface finish, roundness, straightness and cylindricity. And when used with Thomson Linear Ball Bushing® Bearings, travel life and load capacity are significantly increased compared to conventional models.
Customization Options
When your linear motion projects require shafting that doesn’t fit within our standard offering, Thomson skilled machinists can perform a wide variety of special machining operations on the ends or along the length of the 60 Case® shaft to provide the exact part needed for your application. Examples of our customization capabilities include drilling and/or tapping, special tolerances, milling, turning, extended lengths, special coatings/finishes and many more.
Where Can You Get Started?
Thomson provides extensive online resources to help you no matter where you may be in the roundrail shafting purchase decision process:
