Reznor 259451 Bearing
Restore optimal drive shaft performance and stabilize your unit heater's blower assembly with the Reznor 259451. This genuine OEM Reznor 1-7/16 CIP B replacement bearing is engineered specifically for commercial and industrial air handling applications where precision rotational support is non-negotiable. Designed to replace worn-out components in high-duty cycle equipment, this 1-7/16 inch bore bearing minimizes friction across the fan shaft, preventing vibration while reducing energy draw and component fatigue.
As a veteran tech knows, a CIP B type bearing (Cast Iron Pillow Block) is critical for maintaining rigid alignment in Reznor HVAC blower motor setups. This heavy-duty unit weighs approximately 3.7 lbs, providing the mass and structural integrity required to handle the radial loads of large fan wheels. If you are hearing clicking, grinding, or experiencing shaft play in your Reznor gas-fired unit heater, swapping in this 259451 bearing replacement is the standard protocol to prevent motor burnout and ensure consistent airflow across the heat exchanger.
Key Benefits- Genuine OEM Component: Ensures exact dimensional fit for 1-7/16" shafts without the need for shimming or field modifications.
- Enhanced Durability: High-grade cast iron pillow block housing provides superior heat dissipation and mechanical strength in high-temperature environments.
- Reduced Friction: Precision-ground internal races facilitate smooth rotation, lowering operational noise and extending the life of the drive belt and pulleys.
- Direct Technical Interchange: Specifically indexed as the official Reznor 259451 for seamless integration into existing drive assemblies.
What are the signs that my Reznor bearing needs replacement?
Watch for excessive vibration in the blower cabinet, audible metal-on-metal screeching during startup, or visible scoring on the drive shaft. If the shaft has more than 1/32" of radial play, the bearing race is likely compromised.
Is the 1-7/16" size a standard measurement?
Yes, this bore size is standard for many mid-to-large scale Reznor unit heaters. Always micrometer the shaft before ordering to confirm your specific model hasn't been modified with a different shaft diameter.
Does this bearing come pre-lubricated?
Most OEM bearings are shipped with a factory base-grease, but we recommend purging and applying a high-temperature HVAC grease according to the manufacturer's maintenance schedule after installation.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
