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.
