    Oil-Embedded Thrust Bearings

    Image of Product. Front orientation. Thrust Bearings. Oil-Embedded Thrust Bearings.
    Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.
    841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.
    Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away if the bearing heats up.

    Dry-Running Metal-Reinforced Plastic Thrust Bearings

    Combine naturally slippery PTFE with the strength of metal. These bearings don't need lubricant, so there's no oil to maintain, drip off, or attract dust. Backed with steel, they're as strong as other all-metal thrust bearings. However, they're best for dry environments since moisture will cause the steel to rust.

    High-Torque Spider Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. High-Torque Spider Couplings.
    With a thick split spider in the center, these transmit higher torque than standard split spider couplings. Connect them to pumps, mixers, and other equipment that generates heavy torque. The spider also prevents metal-to-metal contact between the hubs, so there's no need for lubrication. For a complete coupling, select two hubs, one split spider, and one split spider cover. Choose components with the same trade size to ensure they'll fit together.
    Hubs

    Hub-Mount Screw-Clamp Bushings

    Image of Attribute. Side1 orientation. Hub-Mount Screw-Clamp Bushings.

    Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

    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.

    Shock-Absorbing Grid Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. Shock-Absorbing Grid Couplings.
    A strip of flexible spring steel (known as a grid) absorbs sudden load increases from motor startups, emergency braking, and other shock loads. They're commonly found in wire drawing and cutting machines, pulverizers, and mixers. For a complete coupling, select two hubs and a grid kit. Choose components of the same trade size to ensure they'll fit together.
    Hubs
    Image of Product. Front orientation. Flexible Shaft Couplings. Shock-Absorbing Grid Couplings, Hubs.
    The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
    Black-Oxide Steel—Typically chosen for their appearance, these hubs have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    Set-Screw Shaft Mount—Screws dig into your shaft for a secure hold.

    Grid Kits
    Image of Product. Front orientation. Flexible Shaft Couplings. Shock-Absorbing Grid Couplings, Grid Kits.
    The grid wraps around the teeth of both hubs to spread the force of starts, stops, and reversals. When the shock load hits, the grid flexes to spread out the load. After the load passes, the grid straightens back out.
    Spring Steel—Use these hard, rigid grids for high-stress applications. They're best for dry environments, since moisture will cause them to rust.

    Set Screw Two-Piece Shaft Collars

    Image of Product. Front orientation. Shaft Collars. Set Screw Two-Piece Shaft Collars.
    Attach these traditional collars anywhere along a shaft when other components are already installed or you can't access the ends. Their set screw digs into the shaft for a tight, permanent 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.

    Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.
    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.
    Chrome-Plated Carbon Steel—Resist moisture and mild cleaning solutions better than zinc-plated collars.
    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.
