    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.

    Splined Rotary Shafts

    Often used in hydraulic and other high-torque applications, these shafts have evenly spaced teeth to transmit heavy rotational loads. They handle more torque and last longer than keyed shafts since they have multiple contact points. Pair them with splined sleeve bushings (sold separately). Compatible bushings and components slide right along the splines, making these shafts a good choice for frequent disassembly and adjustments.
    Fully Parallel Splined

    The large, straight-sided teeth resemble machine keys and transmit more torque than involute-spline teeth. These shafts are fully splined, so you can mount components anywhere along their length.
    Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.
    Sleeve Bushings—Transmit rotary motion or position loads along a shaft. These bushings also work as couplers—they can join two splined shafts when welded into place.
    Flanged Sleeve Bushings—The flange has mounting holes for attaching your load.

    Combine a splined section that handles high torque and a round section for mounting gears, sprockets, and bearings. The parallel splines have large, straight-sided teeth that resemble machine keys and transmit more torque than involute-spline teeth.

    Handle misalignment and reduce vibration and wear. Curved teeth, similar to those on a gear, make more contact with a bushing than parallel-splined teeth. These shafts are fully splined, so you can mount components anywhere along their length.
