Carrier 50DK509555 Bearing Bracket

The Carrier 50DK509555 Bearing Bracket is a critical OEM replacement HVAC part engineered to maintain structural integrity in high-demand belt-drive blower assemblies. As the verified replacement for 50BA409432, this bracket is built to factory tolerances to ensure exact shaft alignment, which is vital for preventing premature bearing failure and reducing mechanical vibration during high-speed rotation. Field technicians recognize this heavy-duty component for its ability to stabilize the fan motor housing, particularly in Carrier rooftop units and large tonnage air handlers.

Constructed from high-strength alloy, the 50DK509555 HVAC bracket features a corrosion-resistant finish that stands up to the rigorous cycling and moisture typical in commercial cooling systems. This genuine Carrier part measures approximately 11.2 inches by 11.3 inches, providing a precise footprint for rapid installation without the need for field modifications. Replacing a fatigued or cracked bracket with this factory-authorized motor support restores the original equipment specifications, ensuring quiet operation and optimal airflow efficiency across the coil.

• Ensures precise shaft alignment to mitigate radial load stress on the blower motor bearings.
• Directly compatible with a wide range of Carrier and Bryant commercial equipment, serving as the official superseded part for 50BA409432.
• Corrosion-resistant alloy construction extends the service life of internal fan components in harsh environments.
• Reduces system noise and vibration by providing a rigid, stable mounting point for rotating assemblies.

Is the 50DK509555 a direct fit for older 50BA409432 brackets?
