Keyed Rotary Shafts

Match with a machine key to prevent slipping while transmitting torque to gears and other components. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

Fully Keyed

Mount components anywhere along the length of these shafts. For secure torque transmission, slide a component from either end and lock it into place with an ANSI machine key (sold separately).

Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.
