Selecting Compatible Lead Screws and Nuts
More
Metric 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, these 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 size and travel distance per turn. 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.

Root diameter indicates the diameter the ball screw will be after machining away the threads.
