    For Double Strand

    Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
    Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.
    Corrosion-Resistant 18-8 Stainless Steel—Won't corrode from frequent washdowns and mild chemicals, including ammonia often found in cleaning solutions.
    Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.
    Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

    Idler Sprockets

    Maintain constant tension on your roller chain to reduce wear and vibration. These sprockets press against the chain to take up slack and rotate freely on bearings to keep the chain moving smoothly. They’re often paired with roller chain tensioners.

    Needle-Roller

    Bearing

    Ball Bearing—Smoother than smooth—the balls inside these bearings roll nearly friction-free to handle high speeds. All are sealed to keep lubricant in and dust out.
    Sleeve Bearing—With no moving parts, sleeve bearings are best for dirty environments. They generate more friction than ball bearings, making them less suitable for high-speed applications. Made of porous bronze embedded with oil, all are self-lubricating.
    Needle-Roller Bearing—These bearings rotate smoothly under your heaviest loads.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
    Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.

    Ball Bearing

    Ball Bearing—Smoother than smooth—the balls inside these bearings roll nearly friction-free to handle high speeds. All are sealed to keep lubricant in and dust out.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

    Flat Sprockets

    Image of Product. Front orientation. Drive Sprockets. Flat Sprockets.
    Save space and cut weight—these sprockets don’t have a raised hub so they’re best for tight spots and lightweight designs. Bolt or weld them to components and mounting surfaces, or add a custom hub. Although they are versatile, they’re harder to align than sprockets with hubs.
    Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
    Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

    Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Taper-lock bushings mount flush inside the sprocket hub for a slim profile. Mount a bushing (sold separately) on your shaft, slide the sprocket over it, and tighten the included set screws. As you tighten, the bushing grips the shaft and pulls it into your sprocket for a secure hold.
    Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
    Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.

    Sprockets for Two Single-Strand Roller Chains

    Image of Product. Back orientation. Drive Sprockets. Sprockets for Two Single-Strand Roller Chains.
    Drive two single-strand roller chains with a single sprocket. Commonly known as double single sprockets, these have a row of teeth on each side. They're often used to link chains in a series over long distances (a setup known as daisy chaining) or to drive one shaft with two chains for increased load capacity.
    Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

    Metal Spur Gears

    Our strongest spur gears for transferring motion. They’re better than plastic gears for high-load, high-speed, and heavy duty applications. Combine a gear and rack to convert rotary motion into linear motion. To minimize your footprint, mount one or more standard gears inside of an internal gear.
    Combine gears with different numbers of teeth to change speed and torque in your assembly. For components to mesh correctly, they must have the same pressure angle and pitch/module.
