    Spider Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. Spider Couplings.
    With two hubs gripping a rubbery spider in the center, these couplings damp vibration and transfer torque while flexing to handle misaligned shafts. The metal hubs never touch each other, so there's no need for lubrication. Also known as Lovejoy® couplings. For a complete coupling, select two hubs and one spider or two hubs, one split spider, and one retaining ring. Choose components with the same trade size to ensure they'll fit together.
    Hubs
    Image of Product. Front orientation. Flexible Shaft Couplings. Spider Couplings, Hubs.
    The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
    Keyed—Mount onto shafts with a matching keyway.
    Iron—Best for dry environments, since moisture will cause these hubs to rust.
    Set-Screw Shaft Mount—Screws dig into your shaft for a secure hold.

    A flexible center fits between hubs to enable torque transfer and damp vibration.
    Buna-N—Highly tear resistant and the best choice to absorb vibration and shock.
    Polyurethane Rubber—Resist tearing better than Buna-N and provide a balance of stiffness and moderate vibration damping.
    Hytrel—Stiffer than Buna-N, these spiders transmit torque from one shaft to the other almost fully but offer minimal vibration damping.

    High-Misalignment Tire Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. High-Misalignment Tire Couplings.
    With a large, flexible rubber tire, these withstand the highest misalignment of any coupling while reducing vibration. For a complete coupling, select two hubs, one tire, and two bushings. Choose components of the same trade size to ensure they'll fit together.
    Hubs

    Set Screw Shaft Collars

    Image of Product. Front orientation. Shaft Collars. Set Screw Shaft Collars.
    Slide these traditional collars from one end of the shaft and tighten the set screw. They dig into the shaft for a secure hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.
    Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
    Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
    316 Stainless Steel—More corrosion resistant than 303 stainless steel collars. These collars withstand salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.
    Aluminum—One-third the weight of steel and corrosion resistant.

    Wider and thicker with larger clamping screws, these deliver a more powerful hold than standard two-piece collars. Attach them anywhere along a shaft when other components are already installed or you can't access the ends. They grip evenly without marring the shaft, so you can reposition or remove them later.
