L Series Quick-Disconnect Timing Belt Pulleys
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.
