The H21 H-Bushing is a precision tapered mounting bushing designed to securely attach pulleys, sprockets, and hubs to a shaft in power transmission systems. With a 1-5/16" bore, this bushing provides a tight, concentric grip that helps reduce vibration and prevent slippage during operation. The split taper design allows the bushing to clamp firmly to the shaft when tightened, ensuring dependable performance while still allowing straightforward removal during maintenance—because when drive components stay exactly where they belong, machines run smoother and repairs stay simpler.
