Overview

WorldWide Electric builds the everyday NEMA gear reducers that keep conveyors, mixers, pumps and screw conveyors running: shaft mount reducers sized to the AGMA standard, cast iron, stainless and aluminum worm reducers, and helical inline, helical-bevel and parallel-shaft units with a NEMA C-face quill input. The range is stocked across North America, so when a common reducer fails the replacement can usually ship fast.

Most units are built to the same footprint as the reducers they replace. Use the interchange tables to find the WorldWide Electric equivalent of a Dodge TXT, Falk, Browning, Hub City, Boston, Grove or Morse unit, or send us the nameplate and we will match it for you.

* Not dimensionally interchangeable with this manufacturer, per WorldWide Electric. Check mounting dimensions before ordering, or send us the nameplate. For the screw conveyor version of a 15:1 or 25:1 shaft mount, substitute SCSMR for SMR. WorldWide hollow bore worm gearboxes have one bore diameter per centre distance.

Helical inline, helical-bevel and parallel-shaft units

The WINL, KAN/KHN and FHN series are dimensionally equivalent to the R, K and F series units from leading European gearmotor brands, with a NEMA quill input that accepts any C-face motor. Send us the model code from your existing unit and we will confirm the match.

Frequently Asked Questions

Is a WorldWide Electric reducer a true drop-in for my Dodge TXT or Boston unit?

The SMR shaft mount reducers are dimensionally interchangeable with Dodge TXT, and the interchange tables above list the equivalent for Falk, Browning, Hub City and other shaft mount brands. For worm reducers, WorldWide Electric notes that its units are not dimensionally interchangeable with the brands marked with an asterisk, so check the mounting dimensions for those. Send us the nameplate and we will confirm the fit before you order.

What do you need from me to quote a replacement?

The nameplate details (manufacturer, model, ratio and serial number) or clear photos, plus the motor frame or input type and the output shaft or bore size. If the nameplate is gone, the centre distance or shaft mount size and the shaft sizes are usually enough.

How quickly can I get a unit?

WorldWide Electric stocks its reducers across North America, so common sizes usually ship quickly. Tell us the model and we will confirm stock and lead time.

Do you have the motor to match?

Yes. Gordon Russell is an authorized WorldWide Electric motor distributor, so we can supply the reducer and the C-face motor together. See electric motors.

Can you rebuild my existing reducer instead?

Our shop rebuilds most gearbox brands and sizes. For small NEMA reducers a new WorldWide Electric unit is often faster and cheaper than a rebuild; we will tell you which makes more sense.

Parts & Service

We supply WorldWide Electric reducers, shaft mount accessories (bushing kits, screw conveyor drive shafts and flanges) and spare parts, and our shop rebuilds most gearbox brands and sizes. For parts or a replacement, send us the model and serial number from the nameplate using the form below. See also: all industrial gearboxes and electric motors.

Replacing a reducer? Send the nameplate details or photos and the motor frame. Sizing a new drive? Tell us the motor power and speed, the output speed or ratio, and the mounting. A Gordon Russell specialist will follow up with pricing, stock and lead time.
