    Keep your drive system in sync. Trapezoidal teeth mesh with matching belts to synchronize motion. With the original tooth profile, these pulleys handle enough torque for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD pulleys.
    Steel and 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. 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.

    High-Torque HTD Timing Belt Pulleys

    Image of Product. Front orientation. Timing Belt Drive Pulleys. High-Torque HTD Timing Belt Pulleys, Bushing Bore.

    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.

    Quiet-Drive Tire-Track Timing Belt Pulleys

    Bushing Bore

    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. 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.
