    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.

    Plastic Spur Gears

    Made of plastic, these spur gears run more quietly than metal gears and have good corrosion and chemical resistance. However, they’re not as strong as metal gears, so they’re best for light duty applications. Combine a gear and rack to convert rotary motion into linear motion.
    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.

    20° Pressure Angle—The current industry standard, these 20° pressure angle spur gears have thicker, stronger teeth than 14½° pressure angle gears.
    14 1/2° Pressure Angle—A former industry standard, 14½° pressure angle gears are often found in older machinery.
    Acetal—Acetal gears absorb less water than nylon gears, so they’re less likely to swell.
    Nylon—Nylon gears are wear resistant, but will swell and weaken over time when wet.

    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.

    Image of Attribute. Front orientation. Contains Annotated, Border. Modified Curved (GT) Teeth.
    When precise synchronization is crucial, these pulleys minimize play (backlash). They’re often found in 3D printers, where accurate positioning is essential. Their curved teeth fit snugly with matching belts. Compared to pulleys with standard trapezoidal teeth, these pulleys transmit about three times more torque and run at higher speeds. All are compatible with Gates PowerGrip GT, 2GT, GT2, GT3, and GT4 series.
    Corrosion-Resistant Aluminum—Won't rust in wet environments and one-third the weight of steel and iron. However, aluminum pulleys are not as strong as iron and steel.
    Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.
