    Ball Screws and Nuts

    Image of ProductInUse. Front orientation. Contains Inset. Ball Screws and Nuts. 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.

    Root diameter indicates the diameter the ball screw will be after machining away the threads.
    Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

    Metric Clamping Lead Screw Collars

    Image of Product. Front orientation. Lead Screw Collars. Metric Clamping Lead Screw Collars.
    Thread these one-piece collars onto a metric lead screw to separate and position components, or use them as an end stop to limit travel. Made of black-oxide steel, they have mild corrosion resistance. Tighten the clamping screws to secure.
    To ensure compatibility, please select a collar that has the same thread type, direction, size, pitch, and number of thread starts as your lead screw.
