Thread-Mount Idler Rotary Shafts
Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications.
Shafts with retaining ring grooves come with a retaining ring and spacers to position your component and hold it in place.

Ball Screws and Nuts
Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread direction and size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
