Rotary Shafts

Pair with gears, sprockets, and bearings to transmit rotary motion. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

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.
