Lennox 50G17 Blower Shaft
The Lennox 50G17 Blower Shaft (model LB-53985C) is a critical mechanical component engineered for high-demand HVACR circulation systems. Fabricated from C1045 steel, this 1-3/16" diameter x 54" length shaft is designed to transmit rotational torque from the drive motor to the blower wheel with minimal runout. For technicians servicing Lennox G13 and G19 series units, this OEM replacement ensures exact tolerances to prevent premature bearing wear and vibration-induced fatigue. The assembly features a precision-machined 1/4" keyway and blower flat, facilitating a secure, slip-free interface with pulleys and hubs. This heavy-duty blower motor shaft replacement is essential for maintaining the static pressure requirements of commercial and industrial air handlers. By utilizing a genuine Lennox part, contractors can maintain system balance and avoid the structural risks associated with undersized or lower-grade aftermarket steel rods.
Key Benefits:- OEM Compatibility: Exact drop-in replacement for Lennox 50G17 and LB-53985C specifications, specifically for G13 and G19 blowers.
- High-Grade Material: Constructed from C1045 industrial steel for superior tensile strength and resistance to bowing under high RPMs.
- Precision Machining: Includes a standard 1/4" keyway and flat spot to ensure a locked connection between the motor drive and blower assembly.
- Enhanced Stability: The 54-inch length provides the necessary reach for large-cabinet furnaces while maintaining rigid rotational alignment.
- What are the exact dimensions of the 50G17 shaft? The shaft is 54 inches in length with an outer diameter (OD) of 1-3/16 inches (1.187").
- Is this shaft compatible with non-Lennox systems? While designed as a Lennox OEM replacement, it can be used in any application requiring a 1-3/16" C1045 steel shaft with matching length and keyway specifications.
- Why use C1045 steel instead of standard cold-rolled steel? C1045 provides a higher carbon content, offering better durability and resistance to the shear forces typical in large-scale air handling units.
