    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.
    Lightweight Anodized Aluminum—One-third the weight of steel and corrosion resistant with an ultra-hard coating that resists wear. While the coating is hard, these shafts have a soft core, so they should be used with linear sleeve bearings to avoid denting the shaft.
    Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.
