About Shafts

D-Profile Rotary Shafts
A flat surface area allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings. 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 tight diameter and straightness tolerances.
1045 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. They are stronger than aluminum and stainless steel shafts but not as corrosion resistant. 303 stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine.

Tapped D-Profile Rotary Shafts
Tapped D-Profile End × D-Profile End
Connect these internally threaded shafts directly to threaded components, or use a fastener to secure. They have a flat surface area that allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings. 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. All are turned, ground, and polished to meet tight diameter and straightness tolerances.
