Daikin-McQuay 2456104 Fan Bearing Assembly

The Daikin-McQuay 2456104 Fan Bearing Assembly is a critical OEM replacement part designed for high-performance air handling and HVAC applications. Engineered for precision alignment, this industrial fan bearing ensures the stable rotation of blower shafts, directly impacting the mechanical integrity of the drive assembly. Unlike generic alternatives, this Daikin 2456104 bearing is manufactured to strict tolerances to manage radial loads and maintain shaft concentricity. For contractors, installing a genuine McQuay 2456104 assembly means mitigating vibration-induced wear on the motor and drive belts, effectively reducing operational noise and preventing premature shaft fatigue. Whether you are performing routine maintenance on a rooftop unit or troubleshooting airflow issues in a commercial air handler, this assembly provides the specific load-bearing capacity and heat dissipation required for continuous duty. Proper lubrication and professional installation of this replacement HVAC fan bearing ensure optimal system static pressure and consistent airflow delivery.

• OEM Precision: Ensures a direct drop-in fit for Daikin-McQuay fan assemblies, eliminating the need for field modifications.
• Vibration Dampening: High-grade materials minimize resonance, protecting the blower wheel and motor from mechanical stress.
• Enhanced Durability: Optimized for high-RPM commercial fan duty to prevent bearing seizure and shaft scoring.
• Operational Efficiency: Reduces frictional resistance to maintain design airflow and lower energy consumption.

What are the signs that a Daikin 2456104 bearing needs replacement?
Technician indicators include increased audible friction (grinding or squealing), excessive shaft play, increased vibration in the housing, or visible grease leakage from the seals.

Is this bearing assembly compatible with older McQuay air handlers?
Yes, this genuine OEM part serves as the standard replacement for legacy McQuay equipment that specifies part number 2456104, ensuring original factory specs are maintained.

Does this assembly include the locking collar and housing?
The 2456104 is a complete bearing assembly designed for immediate mounting and integration into the existing blower support structure.
