Dayton 30D490 Motor Mounting Kit 5-1/2 in

Motor Mounting Kit for 5-1/2 Inch Applications

The Dayton 30D490 kit provides hardware to secure motors in place where a 5-1/2 inch diameter mounting pattern is required. It is built from steel for structural rigidity in HVAC blower assemblies. The kit addresses installations where the motor frame does not match the original equipment dimensions. It suits maintenance technicians and installers adapting non-standard NEMA frame motors to existing housings.

Suits non-standard frame retrofits.

This hardware is intended for situations where additional motor length is necessary to bridge the gap between the motor body and the mounting surface. It supports motors with 4.4 inch and 5.6 inch diameters that fall outside standard frame dimensions. Installers replacing a motor with an exact dimensional match will not need this adapter kit. Buyers seeking vibration isolation mounts or flexible couplings should look at different product types.

5-1/2 inch mounting diameter defines fit

The critical specification is the 5-1/2 inch mounting circle diameter that the kit establishes between the motor and the blower housing. Verify that the target application calls for this exact bolt-circle size before ordering. The kit enables the use of 4.4 inch and 5.6 inch diameter motors within that larger pattern. No other dimensions or load ratings are supplied for selection.
