Thread-Mount Idler Rotary Shafts


Retaining-Ring-Grooves End	Retaining-Ring-Grooves End

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications.

Retaining-Ring-Grooves End—Shafts with retaining ring grooves come with a retaining ring and spacers to position your component and hold it in place.

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.

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.
