H Series Quick-Disconnect Timing Belt Pulleys
Move 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 H series (heavy) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

High-Strength Ultra-Quiet Timing Belt Pulleys
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.
