About Shafts

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Shafts for Support Rails

Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. The tapped mounting holes match those on our Support Rails.

Support-Rail Shafts

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating.

Tapped Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure.

Tapped D-Profile Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure. They have a flat surface area that allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.
