About Shafts

Keyed Rotary Shafts
Combine these shafts with a machine key (not included) to transmit torque to gears, sprockets, and other power transmission components. All have an ANSI standard keyway (keys not included; see our selection of key stock). Their edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, or 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.

Linear Motion Shafts
Smooth, hard, and wear resistant, these 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. 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. Carbon steel shafts are good for general purpose use.
Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 420 and 440C stainless steel shafts have good corrosion resistance and are harder than 17-4 PH stainless steel shafts, so they better resist wear.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Linear Motion Shafts with Material Certification
For your compliance and quality assurance needs, these shafts come with a material certificate with a traceable lot number. These shafts work with linear bearings to reduce friction in manual and automated systems, such as packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances. This allows them to evenly distribute loads, reduce vibration, and improve accuracy and stability.
Made from carbon steel, they’re strong and good for general purpose use. Their surface is hardened while the center remains soft enough to absorb stress from shifting loads. All have chamfered edges to remove sharp corners, reducing damage to bearings, housings, and other components during installation.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
