    Keep HTD timing belt systems running tightly with these idler pulleys. Curved teeth press against the belt as bearings rotate freely, reducing vibration and wear. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series. Idler pulleys are often used with belt tensioners.
    Iron—Strong, but best for dry environments since moisture will cause them to rust.

    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.
    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.

    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.

    Get pitch-perfect compatibility with these free-spinning pulleys. They mesh with belts that have curved GT-profile teeth, reducing vibration and wear. As they rotate on their bearings, these pulleys press up against belts to reduce slack and keep the system moving smoothly. All are compatible with GatesPowerGrip GT, 2GT, GT2, GT3, and GT4 series. Idler pulleys are often used with belt tensioners.
    Corrosion-Resistant Aluminum—Lightweight and resist rust in wet environments. Although aluminum pulleys are one-third the weight of iron pulleys, they aren't as strong.
    Without Teeth—These pulleys press against the smooth side of the belt instead of the toothed side to maintain tension.

    Image of Attribute. Front orientation. Contains Annotated, Border. Curved (HTD) Teeth.
    No need for set screws—these pulleys have bores with six walls that engage with the shaft to transfer torque. They're a good choice when your setup needs to come apart frequently since there aren't extra mounting steps such as press fitting or installing bushings. These pulleys have curved HTD teeth that interlock with the matching belt better than trapezoidal teeth, so they transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP 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.
