Fasco 35-386 Resilient Base
The Fasco 35-386 Resilient Base is a critical mounting component designed specifically for 3.3-inch diameter motors, providing a stable 3.5-inch shaft height (center line). Built for industrial and commercial HVAC applications, this cradle motor mount utilizes a 3.86-inch ring-to-ring dimension to ensure precise alignment within the blower housing. The resilient base design is engineered to isolate operational vibrations, significantly reducing decibel levels and preventing harmonic resonance through the ductwork. Constructed from heavy-gauge steel, the Fasco 35-386 offers the structural integrity required for high-torque startups and continuous duty cycles. This HVAC motor mounting bracket is a direct replacement for standard NEMA 3.3" frame footprints, making it an essential stock item for contractors performing motor swaps in tight centrifugal blower assemblies where maintaining exact motor shaft height is non-negotiable for belt tension and airflow efficiency.
- Universal 3.3-inch Compatibility: Specifically engineered to fit Fasco and other major brand motors with a 3.3" frame diameter.
- Vibration Isolation: The resilient mount geometry dampens mechanical noise, extending the life of motor bearings and surrounding components.
- Precision Alignment: Maintains a consistent 3.5" center line height to ensure proper pulley or fan blade positioning.
- Durable Construction: Heavy-duty steel frame resists corrosion and maintains rigidity under high thermal loads.
Commonly Asked Questions
Will this base fit a 48-frame motor? No, this is specifically sized for 3.3" diameter motors. A 48-frame motor requires a larger 5-5/8" diameter mount.
How do I measure the ring-to-ring distance? Measure from the center of one resilient mounting ring to the center of the other; the 35-386 measures exactly 3.86 inches.
Does this include the motor clamps? This unit is the base assembly; ensure your motor includes or reuse your existing mounting clamps for installation.
