XH Series Quick-Disconnect Timing Belt Pulleys
Securely carry heavy loads—these pulleys mount with quick-disconnect (QD) bushings (not included) for a better grip on the shaft than set screws and press-fit pulleys. They are XH (extra heavy series) with trapezoidal teeth. Made from iron, these pulleys are strong and resist wear. A black-oxide coating protects them from corrosion in dry environments.
