Precision High-Torque GT Timing Belt Pulleys

Finished Bore

Bushing Bore

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.

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.

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.

GT Timing Belt Idler Pulleys

Toothed

Without Teeth

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.

Iron—Strong, but best for dry environments since moisture will cause them to rust.

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.
