Daikin-McQuay 106959460 Bearing Flange

The Daikin-McQuay 106959460 Bearing Flange is a critical structural component engineered for high-performance HVAC blower assembly and motor support systems. Designed to accommodate a 1-1/4 inch shaft diameter, this heavy-duty flange provides the necessary axial and radial stability for industrial-grade centrifugal fans and air handling units (AHUs). This OEM Daikin part ensures precise alignment within the bearing housing, reducing vibration and preventing premature wear on the shaft and bearings during high-RPM operation. Whether you are performing a routine overhaul or a critical emergency repair, utilizing a genuine industrial bearing flange is essential for maintaining the mechanical integrity of McQuay chillers and rooftop units. Its robust construction resists thermal expansion and mechanical fatigue, making it a reliable choice for HVAC motor mount repair applications where tolerances are tight and downtime must be minimized.

Key Technical Benefits:

• Precision Alignment: Engineered to hold 1.25 inch bearings securely, ensuring concentric rotation and reducing system noise.
• Industrial Durability: Cast and machined to withstand the high torque and static pressure loads typical of commercial HVAC systems.
• OEM Compatibility: Direct replacement for Daikin-McQuay 106959460, eliminating the fitment issues common with generic aftermarket mounting hardware.
• Operational Stability: Minimizes oscillations in the drive assembly, extending the service life of both the belt drive and the internal blower components.

Common Installation Questions:

Does this flange include the bearing insert?
This part number refers specifically to the bearing flange housing; the internal bearing insert must be sourced separately based on your specific load requirements.

Is this compatible with older McQuay horizontal AHUs?
Yes, the 106959460 is a standard specification for several generations of McQuay and Daikin air handlers utilizing a 1-1/4" blower shaft.

What is the bolt hole pattern for this flange?
This is a standard industrial mounting pattern designed to align with factory-drilled blower bulkheads and support frames for seamless integration.
