Precision High-Torque GT Timing Belt Pulleys
 |
Finished 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.
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.

High-Torque HTD Timing Belt Pulleys
 |  |
Finished Bore |
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.
