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.
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.

High-Strength 1045 Carbon Steel Rods and Discs
Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.
Ground rods are decarb-free for a uniform surface that will consistently accept heat treating.
If you don't see the size you're looking for, please specify a length under additional rod lengths.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
