    Rotary Shafts

    Image of Product. Front orientation. Rotary Shafts.
    Pair with gears, sprockets, and bearings to transmit rotary motion. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.
    Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.
    Chrome-Plated Carbon Steel—The chrome plating creates a hard, protective barrier that withstands moisture. However, it can chip or flake under repeated impact or shock loads.

    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
    Image of Product. Front orientation. Rotary Shafts. Splined Rotary Shafts, Fully Parallel Splined.
    Image of Attribute. Front orientation. Contains Annotated. Rotary Shafts. Splined Rotary Shafts, 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.
