Tapped Linear Motion Shafts
Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed. Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. Shafts 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.
440C stainless steel shafts are more corrosion resistant than steel shafts but can be more difficult to machine.

Metric Partially Threaded Studs
Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. These studs are steel for strength and wear resistance. They’re best for dry environments, since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.
