Threaded Linear Motion Shafts
with Retaining
Ring Grooves
Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory. 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.
1060 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use.

Threaded Rotary Shafts
Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts. 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.
Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant. 1045 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. 4140 alloy steel shafts have a higher yield strength than 1045 carbon steel shafts for supporting heavier loads; however, they are more difficult to machine. They are hardened for increased wear resistance. 303 stainless steel are more corrosion resistant than steel shafts but also more difficult to machine. They are annealed (softened) for increased corrosion resistance.
