Carry heavy loads without slippage—pulleys mount with quick-disconnect (QD) bushings (sold separately) for a more secure grip on the shaft than set screws. Bushing is not included. Pulleys are L series (light) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

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.

Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.
Press-fit mount pulleys come machined to the for shaft diameter size and are machinable up to the for maximum shaft diameter size.
Bushing-mount pulleys grip the shaft more securely than pulleys that press fit. Quick-disconnect (QD) bushings sold separately.
