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.
