Metric End Supports for Lead Screws and Ball Screws
A set of ball bearings reduces friction and secures the end of a ball or lead screw. End supports handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw). Note: The end of your ball or lead screw must be machined before installing it into an end support.

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.
