    Linear Shafts

    Image of Product. Front orientation. Linear Shafts.
    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.
    Chrome-Plated Steel—Combine the strength of steel and the corrosion resistance of stainless steel. The chrome plating creates a hard, protective barrier on the surface of the shaft. However, the plating can chip or flake under repeated impact or shock loads.
    Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

    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.

    Tight-Tolerance Linear Shafts

    Image of Product. Front orientation. Linear Shafts. Tight-Tolerance Linear Shafts.
    With a diameter tolerance that's at least two times tighter than our standard linear shafts, these distribute loads more uniformly, reduce vibration and wear, and improve accuracy and stability. These shafts are turned, ground, and polished to tight tolerances and hardened to resist wear. Use with linear bearings to create smooth, precise motion.
    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.

    Build-Your-Own Support-Rail Shafts

    Choose a shaft and a matching support rail in the profile you need to create a custom setup for your machine’s layout. Tapped holes drilled along the length of these shafts match up with holes on support rails for quick alignment and setup. The support rails prevent bending and bearing misalignment under moderate to heavy loads. Pair these shafts with linear bearings to create smooth, precise motion. They are turned, ground, and polished to tight tolerances and hardened to resist wear.
    Cut the support rails and shafts to size or mount them end-to-end for long runs. Then, align the mounting holes on the shafts with those on the rails and fasten them with socket head screws (not included). After assembly, test for alignment to guarantee smooth motion.
