Resilient Ring Mounting Base for NEMA 42 Motors

This Dayton 22F212 mounting base fits NEMA Frame 42 motors with a five-inch diameter and a two-and-a-half-inch ring diameter. It provides a stable foundation for HVAC blower installations where vibration isolation is required. The grey-finished unit suits commercial and industrial air-handling equipment.

Bolt Pattern and Ring Spacing for Direct Replacement

Two sets of bolt-hole spacings measure one-and-three-quarter inches by two-and-three-quarter inches in length and four-and-a-quarter inches in width, while the ring-to-ring distance is five-and-a-half inches. These dimensions allow the base to match existing mounting footprints without drilling new holes. Overall height is two-and-fifteen-sixteenths inches, length five-and-nine-sixteenths inches, and width six inches.

Two Clamps Included for Immediate Installation

The package supplies two clamps that secure the motor rings to the resilient base, removing the need to source separate hardware. This reduces assembly time during maintenance or new blower builds. No additional accessories or software are bundled with this mechanical component.
