    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.

    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.
