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.

Corrosion-Resistant 304 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. However, these shafts are more difficult to machine than carbon steel shafts.

Highly Corrosion-Resistant 316 Stainless Steel—More corrosion resistant than 303 and 304 stainless steel shafts. They stand up to salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.
