Lennox 86H55 Bearing Bracket

The Lennox 86H55 Bearing Bracket is a critical OEM component designed for high-performance blower motor support and shaft alignment in residential and commercial Lennox air handlers and furnaces. Engineering specifications confirm that the 86H55 is the direct replacement for the 86H5501, featuring a robust 3-leg configuration and a 1-inch bearing socket. Constructed from high-strength, corrosion-resistant steel, this bracket provides the necessary structural rigidity to prevent blower wheel oscillation and mechanical run-out. For service technicians, ensuring a precise fit with this genuine Lennox replacement part is vital to mitigating harmonic vibration and reducing decibel levels during high-velocity airflow cycles. Replacing a warped or fatigued bracket with this OEM blower bearing support preserves the concentricity of the blower assembly, preventing localized heat buildup on the shaft and protecting the motor from premature failure. Whether you are performing a seasonal overhaul on a CHA16 or a GHP16 series unit, the Lennox 86H55 offers the exact mounting geometry required for seamless field integration.

• Ensures precise shaft alignment to eliminate excessive HVAC blower motor vibration.
• Direct Lennox 86H5501 cross-reference for guaranteed compatibility with legacy air handler models.
• Heavy-duty 3-leg steel construction maintains structural integrity under high rotational loads.
• Reduces acoustic resonance, promoting quieter system operation and improved customer satisfaction.
• 1-inch bearing socket accepts standard Lennox replacement bearings for streamlined servicing.

Is the 86H55 the same as the 86H5501 used in older furnaces?
Yes, the Lennox 86H55 is the exact functional and dimensional equivalent of the 86H5501. It is designed to fit the same mounting points in your blower housing.

How do I know if my bearing bracket needs to be replaced?
If you detect audible metal-on-metal grinding, visible stress fractures on the legs, or significant "play" in the blower shaft, the bracket is likely compromised and should be replaced to avoid motor damage.

Does this bracket include the bearing?
This part is the bearing bracket only. The 1-inch bearing must be purchased separately if your existing bearing is seized or worn.
