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. 4140 alloy steel shafts are good for high-stress applications. They are stronger than carbon steel and hardened for increased wear resistance; however, they are more difficult to machine.

Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 304 stainless steel shafts have good corrosion resistance. 316 stainless steel shafts have excellent corrosion resistance.

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