Reznor 194803 Bushing

The Reznor 194803 Bushing is a critical OEM replacement part designed for integration within the venter motor assembly of Reznor gas-fired unit heaters. Serving as a dedicated venter isolator bushing, this component is engineered to provide mechanical decoupling between the venter motor and the mounting plate. By absorbing high-frequency harmonics and structural oscillations, it effectively minimizes vibration and noise transfer throughout the chassis, ensuring the HVAC combustion system operates within specified acoustic and mechanical tolerances.

Specifically matched for Reznor UDAP and UDAS series heaters (sizes 30-400), this bushing is also compatible with UDX and UBX models. For a full assembly refresh, technicians typically require three bushings per motor mount to maintain the 5/16-inch clearance gap necessary for optimal airflow and motor cooling. Utilizing genuine Reznor 194803 hardware prevents premature bearing wear in the venter motor and maintains the structural integrity of the flue duct assembly in both standard power-vent and separated-combustion configurations.

Key Benefits:

• Vibration Dampening: High-density material reduces resonance and protects sensitive control boards from mechanical stress.
• Acoustic Isolation: Minimizes audible "hum" and structural noise for quieter operations in commercial and industrial spaces.
• OEM Precision: Guaranteed fit for venter motor mounting plates across the UDAP/S 30-400 range.
• Extended Component Life: Reduces fatigue on motor studs and flue wrapper components by absorbing operational torque.

Common Questions:

• Is this compatible with all Reznor unit heaters? It is designed for unit sizes 30 through 400. Always verify your heater's model and serial number against the rating plate to ensure a match.
• How many bushings are required for a standard venter motor repair? Most venter assembly installs require three 194803 bushings to properly secure the motor to the bracket.
• Does this bushing ship with mounting screws? This is the individual isolator bushing only; existing hardware or the #10 replacement screw may be required for installation.
