About Shafts

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed. These shafts work with linear bearings to reduce friction in manual and automated systems because they're smooth, hard, and wear resistant. You'll often see them in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.

The surface is hardened, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Chamfered edges remove sharp corners at the end of these shafts, reducing damage to bearings, housings, and other components during installation.

Alloy steel shafts are stronger and resist wear better than stainless steel.

Stainless steel shafts have good corrosion resistance.

Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Support-Rail Shafts

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. Shafts have a smooth surface to reduce friction and wear on linear bearings—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. They are case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.

Two-piece shafts allow you to replace the shaft when it becomes worn.

Carbon steel shafts are stronger than aluminum shafts but not as corrosion resistant. These shafts balance high strength and good machinability, making them ideal for general purpose use.

Stainless steel shafts have good corrosion resistance and are stronger than aluminum shafts.

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; attach using socket head screws (not included). Shafts have a smooth surface to reduce friction and wear on linear bearings—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. They are case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.

1566 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. 440C stainless steel shafts are more corrosion resistant than 1566 carbon steel shafts.

Tapped D-Profile Rotary Shafts

Tapped D-Profile End × D-Profile End

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. Shafts are 1045 carbon steel, a general purpose shafting material that balances high strength and good machinability. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to meet tight diameter and straightness tolerances.
