Reznor 10120 Blower Shaft

The Reznor 10120 Blower Shaft is a precision-engineered 1-inch diameter replacement shaft measuring 39.25 inches in length, specifically designed for high-static heating and ventilation applications. As a critical component in the blower assembly, this shaft ensures concentricity and balanced torque transfer between the motor and the centrifugal wheels. Built for industrial durability, it utilizes high-grade cold-finished steel to maintain structural integrity under continuous thermal stress. This replacement blower shaft is compatible with various Reznor unit heaters and furnace configurations that require a 1-inch bore. When performing a direct swap-out, ensure that bearing lock collars and setscrews are torqued to manufacturer specifications to prevent axial movement or vibration. This OEM Reznor part is essential for restoring airflow efficiency and shaft alignment in commercial HVAC units. Proper installation of this industrial heating part reduces mechanical wear on motor bearings and maintains consistent static pressure across the blower housing.

• Precision Machined: Maintains strict tolerances for 1-inch blower bearings, reducing vibration and mechanical resonance.
• High-Grade Steel Construction: Offers high shear strength to handle the startup torque of large horsepower blower motors.
• OEM Compatibility: Exact dimensional match for Reznor unit heater maintenance, ensuring drop-in replacement without field modifications.
• Corrosion Resistance: Engineered to withstand the temperature fluctuations and moisture levels found in industrial draft environments.
