Lennox 78F43 Blower Shaft
The Lennox 78F43 Blower Shaft (OEM Model LB-50255C) is a critical mechanical component engineered for heavy-duty application in industrial and residential air handling units. Machined from high-grade C1045 carbon steel, this 1-inch diameter shaft is designed to withstand high torque loads and continuous rotational cycles within the blower assembly. With a precision-cut length of 27.25 inches, it features a standardized 1/4" keyway and a flat for secure blower wheel mounting, ensuring zero-slip performance and optimal power transfer from the motor.
For service technicians performing a Lennox blower motor assembly overhaul, this shaft provides the necessary structural rigidity to eliminate vibration and shaft whip in high-static pressure environments. The Lennox HVAC replacement part is essential for restoring internal system balance and maintaining specified CFM outputs. Its robust construction resists fatigue and torsional stress, making it a reliable choice for HVAC blower shaft replacement in compatible Lennox equipment, securing the long-term operational integrity of the air delivery system.
Key Benefits- Industrial-Grade Material: Constructed from C1045 steel for superior tensile strength and resistance to bowing.
- Precision Dimensions: Features a 1" diameter and 27.25" length for an exact fit in Lennox HVAC systems.
- Secure Mounting: Includes a factory-milled 1/4" keyway and flat to ensure a positive lock with the blower wheel.
- Reduced Mechanical Wear: Balanced engineering helps minimize bearing friction and operational noise.
