Ultra-High-Strength Poly Chain Timing Belt Pulleys
Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws. Bushing is not included. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.
