Mounting Base for NEMA 48 Motors

The Dayton 22F214 mounting base fits NEMA frame 48 motors with a 5.6 inch diameter. It provides a resilient ring mount for blower installations in HVAC systems. The gray base includes two clamps for secure attachment. This component suits technicians replacing worn mounts or assembling new blower units.

Upgrade from Rigid or Damaged Bases

A resilient ring base replaces rigid mounts that transmit vibration to ductwork and equipment frames. The jump is worth it when motor noise or vibration shortens bearing life or creates nuisance sound in occupied spaces. The included clamps simplify the swap without fabricating custom brackets. Installers gain isolation without changing the motor footprint.

Handles 6-1/16 Inch Ring Spacing

The base accommodates a compatible ring diameter of 2-1/2 inches and a ring-to-ring distance of 6-1/16 inches. Bolt hole spacings of 1-3/4 inches by 2-3/4 inches in length and 4-1/4 inches in width match standard NEMA 48 patterns. Overall dimensions of 6-1/8 inches length, 6 inches width and 2-15/16 inches height define the installation envelope. It runs out when motor diameter exceeds 5.6 inches or frame size differs from NEMA 48.

Questions about this item

What NEMA frame size and ring-to-ring distance does the Dayton 22F214 mounting base support?

The base is built for NEMA frame 48 and a 6-1/16 inch ring-to-ring distance, matching the motor and blower housing spacing.

How do you install the Dayton 22F214 base, and which step is often missed?

Bolt the base using the 1-3/4 inch and 2-3/4 inch length spacing with 4-1/4 inch width spacing, then secure the two included clamps around the 2-1/2 inch ring — skipping the clamps leaves the motor loose.

What parts of the Dayton 22F214 mounting base may need replacement over time?

The resilient rubber ring and the two metal clamps can wear or fatigue; the gray-painted steel frame itself rarely needs service.
