Dayton Motor Cross Reference
Dayton Motor Cross Reference - WorldWide Electric & NAE Equivalents
Dayton is Grainger's house motor brand - which means millions of installed units and a catalog number system that maps to standard NEMA motors underneath. When the MRO-counter price or lead time stops making sense, the nameplate crosses a Dayton straight to an industrial-brand equivalent.
The Five-Point Cross
| Check | From the Old Nameplate | Must Match? |
|---|---|---|
| HP & RPM | Rated power and full-load speed | Yes - same HP (or one up), same pole count |
| Frame | NEMA frame number (e.g. 184T, 326T) | Yes - frame match = bolt-in fit |
| Voltage / Phase | e.g. 230/460V, 3φ, 60 Hz | Yes |
| Enclosure | ODP, TEFC, TEXP, washdown | Yes, or upgrade |
| Service Factor & Design | SF 1.15, NEMA Design B typical | Equal or better |
Because both brands build to NEMA MG-1, a frame match guarantees the mounting dimensions - details in our frame size chart and nameplate guide.
Where Dayton Lines Typically Cross
| Dayton Line | Duty | Our Equivalent Series |
|---|---|---|
| General purpose (3-phase) | Fans, pumps, machines | Integral TEFC · ODP |
| Premium efficient | Continuous industrial duty | PE / PEWWE |
| Single-phase / capacitor start | Shop & light duty | 1φ Fractional TEFC · ODP |
| Farm duty | Augers, fans, sprayers | Grain Dryer TEFC · 1φ ODP |
| Jet pump | Water systems | Jet Pump 56J |
| Washdown | Food service & processing | Washdown Stainless |
Dayton Cross Notes
Dayton stock numbers (like 6K758) are retail identifiers - the motor underneath is a standard NEMA design, so the nameplate grid carries everything needed: HP, RPM, frame, voltage, SF, enclosure. Two habits worth noting: much of the Dayton fractional catalog rides on 48 and 56 frames with belly-band or resilient mounts (photograph the mounting before ordering), and HVAC-style PSC motors cross by HP, RPM, rotation, and shaft rather than frame alone.
Buying pattern worth reconsidering: if the same Dayton motor fails repeatedly, the application usually wants a duty upgrade - a TEFC in place of ODP, a higher service factor, or cast iron - rather than another identical replacement. That conversation is free: (888) 203-2358.
Frequently Asked Questions
Can I cross a Dayton motor by its Grainger stock number?
Indirectly - the stock number identifies the listing, but the nameplate on the motor states the actual NEMA specs. Send the nameplate photo (or the specs from the listing) and the cross to an equivalent industrial motor is straightforward.
Are industrial-brand motors better than Dayton?
Dayton units are rebranded standard motors of varying manufacture. Crossing to WorldWide Electric or NAE gets you a known factory line, full datasheets and CAD, and often deeper stock in integral HP sizes - at pricing worth comparing on anything over a couple of horsepower.
What is a belly-band mount and can I replace it with a standard motor?
A strap clamp around the motor shell, common on HVAC blowers. Replacements match by diameter, HP, RPM, rotation, and shaft - not NEMA frame. Where the equipment allows, converting to a foot or C-face mount opens far more replacement options.
My Dayton farm motor keeps failing every season. Same again?
Repeat failures signal a duty mismatch - dust in an ODP, marginal starting torque on a loaded auger, or heat. A totally enclosed farm-duty design with high breakaway torque usually ends the cycle for a few dollars more.
Do you match Grainger pricing?
We quote real-time on request - industrial-line pricing on integral HP motors is frequently below MRO-catalog pricing, and sizing help is included. Call with the stock number or nameplate and compare directly.
