Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, ground, and polished to meet tight diameter and straightness tolerances.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. 12L14 carbon steel shafts have a lead additive that makes them easier to machine than any other rotary shaft but also more prone to wear. Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 303 and 440C stainless steel shafts have good corrosion resistance. 316 stainless steel shafts have excellent corrosion resistance.
Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

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, 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. 2024 aluminum shafts are a lightweight, corrosion resistant, and nonmagnetic. They have a T4 temper, which means they have been heat treated for increased strength.
