Custom RoundRail Shafting

RoundRail Shafting 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.

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.
