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.

Partially Keyed

These shafts combine keyed ends with a plain center for versatile assembly. The keyways on the ends lock with the included ANSI machine keys to transmit torque to components such as gears and sprockets. The plain center fits bearings and other round-bore parts.

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

Corrosion-Resistant 303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These shafts are easier to machine than other stainless steel shafts.
