    Hollow Linear Shafts

    Image of Product. Front orientation. ZoomedIn view. Linear Shafts. Hollow Linear Shafts.
    Substantially lighter in weight than standard shafts, these are best for light loads. You can also run wiring, pneumatic tubing, coolants, and lubricants through the shaft's hollow center. Pair with linear bearings and shaft supports to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.
    Steel—Stronger than aluminum and stainless steel. These shafts are best for dry environments since moisture will cause them to rust.
    Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

    Ball Screw/Splines and Bearings

    Image of Product. Front orientation. Contains Annotated. 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.
