Source1 2647212000 Blower Shaft with Keyway 0.75 Inches

Product Description

The Source1 2647212000 is a blower shaft with keyway, sized at 0.75 inches in diameter. This component is a direct replacement part used in HVAC blower assemblies. Blower shafts are critical to the operation of air handling units, furnaces, and fan coil systems. They connect the motor to the blower wheel, transferring rotational force to move conditioned air through the duct system. The keyway feature on this shaft is essential. A keyway is a precision-cut slot machined into the shaft. It accepts a key, which is a small metal piece that locks the blower wheel or pulley securely to the shaft. This prevents slipping under load, which can cause noise, inefficiency, and premature wear on both the motor and the wheel. HVAC technicians often encounter worn or damaged blower shafts during routine maintenance or breakdown service calls. Common failure signs include wobbling blower wheels, excessive vibration, noise during operation, and reduced airflow. Replacing the shaft with a correctly sized, keyed component restores proper alignment and torque transfer. The 0.75 inch diameter is a standard size found across a wide range of residential and light commercial HVAC equipment. This makes the Source1 2647212000 a practical stock item for service technicians who work on multiple equipment brands and models. Source1 is a well-known supplier of OEM-equivalent HVAC replacement parts.
