    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.

    Roller Screws and Nuts

    Image of ProductInUse. Front orientation. Roller Screws and Nuts.
    Precision ground to create more points of contact, these roller screws and nuts are highly accurate and handle much higher loads than ball screws and nuts of the same size. They're most traditionally used to replace hydraulics in linear actuators but can also be used in place of ball and lead screw assemblies because of their high load capacity and precise motion control. In fact, they're almost four times more accurate than our most accurate ball and lead screws. They also last longer than ball screw nuts in systems with lower loads and can handle higher shock loads. However, because they have more contact points, they’re slightly less efficient than ball screws. To ensure compatibility, select components that have the same thread direction and size.

    Highly Machinable 4140 Alloy Steel Rods

    Image of Product. Front orientation. Steel. Highly Machinable 4140 Alloy Steel Rods.
    Often called ETD-150, this modified alloy steel is drawn at high temperatures for excellent strength and machinability. Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress. It is used for a wide range of parts, such as gears, axles, and shafts. These rods have been hardened for added resistance to abrasion and impact.

    Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. To ensure compatibility, select components that have the same thread size and number of thread starts. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.

    Carbon Steel—Carbon steel ball screws and nuts are case hardened, so they resist wear better than standard carbon steel. However, they are less corrosion resistant than black-oxide alloy steel screws and nuts.
