About Shafts

Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. Carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use.
Shafts with chamfered edges 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, 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.

Partially Keyed Rotary Shafts
These shafts have keyways only on the ends, leaving a plain shaft in the center. The keyways work with the included ANSI machine keys to transmit torque to gears, sprockets, and other keyed components. Use the middle of the shaft with bearings and other round-bore components. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to meet tight diameter and straightness tolerances.
1045 carbon steel shafts are stronger than 303 stainless steel shafts. They have excellent machinability, so you can easily cut your own lengths.
