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. Chrome-plated 1045 carbon steel shafts have a 0.0001"-0.0005" thick layer of chrome plating on the outside of the shaft that provides wear resistance and some corrosion resistance.

Ultra-Straight Tight-Tolerance Rotary Shafts
Eight times straighter than standard rotary shafts, these tight-tolerance shafts minimize vibrations and reduce wear to bearings and other components. They also have diameter tolerances that are twice as tight as standard rotary shafts. All are carbon steel, a general purpose shafting material that balances high strength and good machinability. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. Shafts are turned, ground, and polished to meet the diameter and straightness tolerances listed.

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. Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 303 and 304 stainless steel shafts have good corrosion resistance. 303 stainless steel shafts are annealed, which makes them softer than 304 stainless steel shafts but more corrosion resistant. 316 stainless steel shafts have excellent corrosion resistance.

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.

Keyed Rotary Shafts with Material Certification
In addition to diameter tolerances that are twice as tight as standard keyed shafts, these shafts include a traceable lot number and test report. Use them with machine keys (not included) to transmit torque to gears, sprockets, and other power transmission components. Shafts are 1045 carbon steel, a general purpose shafting material that balances high strength and good machinability. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation.

D-Profile Rotary Shafts
Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant.

Splined Rotary Shafts
With a splined profile on one end, these shafts transmit high rotational loads—good for hydraulic systems, machine tools, and other high-torque applications. Compared to keyed shafts, they last longer, handle higher torque, and do not require as tight of a fit. Shafts are 1045 carbon steel, a general purpose shafting material that balances high strength and good machinability. They are 48" long and have six 12"-long splined grooves on one end. The straight end is turned, ground, and polished for a smooth, round finish. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation.
