    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.
    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.

    Pair these pulleys with the strongest timing belts we offer, Ultra-High-Torque GT Timing Belts. They can handle as much torque as roller chain. Their curved teeth fit snugly with matching belts for minimal play (backlash), so these pulleys are good for applications that require precise positioning. All are compatible with Gates Poly Chain GT timing belts.
