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.

These HTD (high torque drive) pulleys have a curved tooth shape that provides higher strength than 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.

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern. The curved teeth on these high-torque drive (HTD) pulleys have more surface contact with belts than traditional trapezoidal teeth, which allows you to apply more torque without damaging belts. These teeth fit together seamlessly to prevent backlash, or unwanted movement of the belt on the pulley, for a smooth, quiet cycle. These pulleys are often used in 3D printing, machine tool drives, robotics, and other applications where precision is essential. They are also known as curvilinear belt pulleys.
Pair pulleys with an HTD timing belt that has the same pitch. The width of your belt should not be larger than the maximum belt width listed.
Aluminum pulleys will not rust in damp or humid environments, but water left on the surface will cause them to corrode. Stainless steel pulleys can be wetted repeatedly without rusting or staining.
Bushing-mount pulleys grip the shaft more securely than press-fit pulleys, but require a quick-disconnect (QD) bushing (not included).

Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners (not included) to remove slack from timing belts. By maintaining tension on the belt, these pulleys reduce wear and vibration in 3D printing, machine tool drives, robotics, and other linear motion applications that require precise positioning.
When replacing an idler pulley, be sure the pulley matches your belt's trade size.
Toothed pulleys are shaped to mesh with the teeth on a timing belt, which reduces wear on the belt's teeth.

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.
