Lennox 64W52 Blower Pulley
The Lennox 64W52 Blower Pulley is a critical power transmission component engineered for high-demand commercial HVAC applications. Featuring a 7.25-inch outer diameter and a 1-inch finished bore, this single-groove (1-groove) pulley is designed to facilitate precise airflow management by efficiently transferring torque from the blower motor to the fan assembly. Constructed from high-grade cast iron (Browning AK74X1 equivalent), it provides the structural rigidity required to minimize rotational vibration and maintain consistent static pressure in Lennox air handlers and rooftop units.
This OEM blower pulley is a direct replacement for Lennox 100244-21 and is compatible with a wide range of T-Class and Strategos units, including models KCA092H4, KGA150S4, and KHB102H4. By maintaining the correct drive ratio, the Lennox 64W52 ensures your centrifugal blower operates within its specified RPM range, optimizing thermal transfer and reducing mechanical stress on the drive belt. For contractors performing preventative maintenance or emergency repairs, this pulley offers the exact tolerance fit needed to restore factory-spec performance without the alignment issues common in universal aftermarket alternatives.
Key Benefits- Precision Machined Bore: The 1-inch bore ensures a secure, slip-free fit on the motor shaft, reducing the risk of keyway damage.
- Optimized Drive Ratio: The 7.25" OD is specifically calibrated to maintain designed CFM output across Lennox K-Series and G-Series equipment.
- Industrial Cast Iron Construction: Provides superior heat dissipation and wear resistance compared to stamped steel pulleys.
- Reduced Vibration: Balanced design minimizes harmonic resonance, protecting blower bearings and extending the life of the drive system.
What is the compatible belt type for the Lennox 64W52?
This single-groove pulley is typically paired with standard A-section or 4L fractional horsepower V-belts, though always verify your specific unit's drive package requirements.
Can this pulley be used to adjust blower speed?
As a fixed-pitch pulley, speed adjustments require changing the motor-side sheave or replacing this component with a different diameter pulley to alter the drive ratio.
Does this fit both gas and electric Lennox rooftop units?
Yes, the 64W52 is utilized across multiple Lennox commercial platforms, including KGA (gas/electric) and KCA (cooling only) models, provided the shaft size matches.
