Dayton Resilient Rubber Motor Mounting Rings
These Dayton motor mounting rings are made from resilient rubber and come as a pair. They replace the mounting rings on 3 3/8 in diameter ring-mounted motors found in Nutone and Broan ventilation units. Each ring has an outside diameter of 1 13/16 in and an inside diameter of 1 1/4 in. The thickness measures 5/16 in.
Suited for direct replacements on compatible
This two-pack suits technicians or homeowners restoring original vibration isolation on the specified Nutone and Broan motor frames. It does not suit installations where the motor frame diameter differs from 3 3/8 in or where a different ring profile is required. Buyers needing other dimensions or materials should look at alternative mounting hardware.
Outside diameter 1 13/16 in
The critical specification is the ring geometry: an outside diameter of 1 13/16 in paired with an inside diameter of 1 1/4 in. These dimensions must match the motor housing and shaft collar exactly for the resilient rubber to seat correctly and absorb vibration. Verify both diameters against the existing rings before ordering.

Questions about this item
How often should the resilient rubber rings be inspected or replaced?
Inspect the rubber rings during routine motor service; replace them if they show cracking, hardening or loss of elasticity.
What is the first limit reached when the motor runs continuously?
The 5/16 in thick rubber will transmit more vibration if it compresses permanently under sustained load.
Do the rings add noticeable noise or heat during all-day operation?
The resilient rubber isolates vibration, so it reduces noise and does not generate measurable heat.
