Leeson Motor Cross Reference

Leeson Motor Cross Reference - WorldWide Electric & NAE Equivalents

Leeson (Regal Rexnord) built its name on fractional and small integral HP motors - the C-face gearmotor inputs, washdown units, and single-phase workhorses scattered through every plant and farm shop. Those are exactly the sizes stocked deepest here, and NEMA standardization makes the cross mechanical.

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.

Leeson Cross Notes

Leeson catalog numbers (e.g. 110086) don't encode specs - the nameplate grid does, so photograph it. Watch three things: many Leeson fractionals are 56 with special shafts or faces (56C, 56H, 56J) - match the suffix, not just the 56; single-phase units list capacitor values worth recording before the motor goes in the scrap bin; and Leeson metric/IEC frames (63–132) cross to IEC equivalents, not NEMA frames - IEC flange kits cover some conversions.

Replacing a Leeson on a worm reducer input? Match the C-face and shaft, or replace motor and reducer together as a gearmotor - sometimes cheaper than the special motor alone.

Frequently Asked Questions

Are Leeson part numbers cross-referenced to other brands?

Not by number - Leeson catalog numbers are arbitrary, so crossing works from the nameplate specs: HP, RPM, frame (with suffix), voltage, enclosure. With those five points, equivalent NEMA motors interchange directly.

What does 56C, 56H, or 56J mean on a Leeson nameplate?

All share the 56 shaft height; C adds a C-face flange, H adds combination base holes (56/143T pattern), J is the threaded-shaft jet pump build. The suffix must match on a replacement or the motor won't mount.

Can I replace a Leeson IEC-frame motor with a NEMA motor?

Not directly - IEC 71/80/90 frames have metric mounting and shafts. Either source the IEC equivalent or adapt with an IEC flange kit where the driven equipment allows; send photos and we'll advise which is cheaper.

My Leeson gearmotor died. Motor only, or whole unit?

Compare prices both ways. If the reducer is healthy and the motor is a standard C-face, replace the motor. If the gearmotor is integrated or worn, a stock C-face motor plus HDR or FHN reducer is often faster and cheaper than an OEM assembly.

Do you stock single-phase replacement motors for Leeson farm duty?

Yes - capacitor-start single-phase TEFC and ODP fractionals cover the common farm sizes, with starting capacitors stocked separately. Match HP, RPM, frame suffix, and voltage off the nameplate.
