High-Strength HTD Timing Belt Pulleys

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 and split-tapered bushings sold separately.
