For technical service and field replacements, the Lau 60-7658-03 (60765803) Interchangeable Hub is the trade-standard solution for securing fan blades to a 3/8" motor shaft. Featuring a dual-profile design, this hub accommodates both hex and round shaft configurations, allowing contractors to carry a single part for multiple propeller types. Engineered from heavy-duty steel, the 60-7658-03 includes extra metal at the mounting surfaces to provide a more secure fit and increased vibration resistance in high-torque applications. This universal interchangeable hub is optimized for 3-blade, 4-blade, and 5-blade propellers commonly found in condenser fan motors and residential HVAC units. The unit comes equipped with a single set screw and the necessary mounting hardware to ensure a positive lock on the shaft, preventing slipping and mechanical wear. Whether you are servicing an attic fan or a commercial condensing unit, this component provides the rigorous tolerance required for high-RPM air movement equipment.
