    Sprockets

    Image of Product. Finished Bore. Front orientation. Drive Sprockets. Sprockets, For Single Strand, Finished Bore.

    Finished Bore

    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.
    Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.

    High-Torque HTD Timing Belt Pulleys

    Bushing Bore

    Image of Attribute. Front orientation. Contains Annotated, Border. Curved (HTD) Teeth.
    Curved teeth engage with the matching belt better than standard trapezoidal teeth, so these pulleys transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
    Iron—Strong but best for dry environments since moisture will cause them to rust.
    Corrosion-Resistant Stainless Steel—Stands up to wet environments and mild chemicals, such as the ammonia in cleaning solutions.
    Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

    The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
    Machine Key—Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.

    Bushing Bore

    Image of Attribute. Front orientation. Contains Annotated, Border. Tire-Track Teeth.
    Crank up the power and turn down the noise. With curved teeth arranged in a tire-track pattern, these pulleys fit snugly into matching belts. The flush fit reduces play (backlash) for more precise movement and up to 25% less operating noise. Compared to pulleys with trapezoidal teeth, they deliver higher torque with less vibration and smoother performance.
    Iron—Strong but best for dry environments since moisture will cause them to rust.
    Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it.
