    Metric Fast-Travel Ultra-Precision Lead Screws and Nuts

    Image of ProductInUse. Front orientation. Contains Inset. Precision Lead Screws and Nuts. Metric Fast-Travel Ultra-Precision Lead Screws and Nuts.
    Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size and number of thread starts.

    Ball Screw/Splines and Bearings

    From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.
    The ball bearings move smoothly and precisely, even at high speeds. They're powered independently, so you can drive one bearing at a time or both together to coordinate movements.
    The ball screw/splines are hardened on the surface, so they stand up to repeated motion. They’re also hollow, so you can run electrical wiring, compressed air tubing, coolants, or lubricant through their center.

    Metric Ultra-Precision Lead Screws and Nuts

    Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.

    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.
