High-Strength GT Timing Belt Pulleys
For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics. Similar to HTD timing belt pulleys, their teeth are curved for high strength. The curved teeth create positive grip engagement with timing belts, so these pulleys do not require re-tensioning—unlike drives using V-belts or sheaves. And unlike chain drives, there’s no metal-on-metal contact, so these pulleys don’t require lubrication.

Ultra-High-Strength Poly Chain Timing Belt Pulleys
Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws. Bushing is not included. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.
