The P&H 18U109D13 Coupling is a shaft coupling from P&H designed to join two shafts in power-transmission systems, providing a secure, keyed connection that preserves alignment under load. It features a 2-3/8" bore and a 5/8" keyway (KW) to accommodate standard shaft sizes and enable torque transfer through a keyed interface. This coupling is specified for applications where precise bore sizing and a compatible keyway are essential for reliable operation in driven machinery.
