Winsmith Gearboxes & Speed Reducers
Right-angle worm, helical inline, helical bevel, and planetary drives from Winsmith — stocked, cross-referenced, and exported by an independent distributor that has been shipping US-built power transmission worldwide since 1950.
Send us a nameplate, an obsolete model number, or a hand sketch. We will confirm the current Winsmith equivalent, quote it, and tell you honestly if a Grove Gear or Electra-Gear unit is the faster or better-priced answer.

Why Source Winsmith Through Jealco
We are an independent distributor, not a single-brand outlet. That matters most when a drive is down and the "right" answer is whichever unit gets to your plant first.
Both Sides of the Interchange
We stock Winsmith and Grove Gear / Electra-Gear. When the Winsmith RD Series crosses to a Grove drive you already have installed, we can quote either one instead of selling you the only brand we carry.
Obsolete Model Support
D-90 Type SE units from decades back are still turning conveyors. Send the nameplate and we will decode the size, ratio, shaft arrangement, and motor frame and identify a current equivalent.
Built for Export
Export has been our core business since 1950. Latin America, the Caribbean, Africa, Asia — crating, HS classification, and documentation handled in-house, not outsourced.
Engineering Before the PO
Ratio, service factor, overhung load, mounting position, and washdown requirements checked before we quote — so the reducer you receive is the one the application actually needs.
Winsmith Product Lines We Supply
Winsmith is headquartered in Springville, New York, with US manufacturing in Springville and Flowery Branch, Georgia, under parent company HBD Industries. Below are the lines we quote most often.

- Planetary Inline, high load capacity
- Motion control C-Minimizer, S-Eliminator
- Lead time 1–3 days (HXI / HXB)
How to Read a Winsmith Model Number
Most replacement calls start with a worn nameplate and a number nobody on site can interpret. Here is how the two most common Winsmith formats break down.
D-90 Type SE (legacy 9xx format)
- 9 — D-90 series designator
- 35 — center distance, 3.50″ (10 = 1.00″, 13 = 1.33″, 17 = 1.75″, 20 = 2.00″, 24 = 2.375″, 26 = 2.625″, 30 = 3.00″, 35 = 3.50″, 43 = 4.25″)
- M — input style: C = C-flange with coupling adapter, M = C-flange with quill adapter, blank = non-motorized
- DTS — basic model + reduction: DB, DT, DV, DL, DN, DJ, DSN, DSF, DSR, DD, WB, WT, WU — then S = single, D = double, X = helical primary
- 2000 — shaft arrangement, motor frame, and output style (00 = solid output; 08–10 = hollow bore sizes)
- EK — ratio code. A8 = 5:1, BT = 7.5:1, B7 = 10:1, C1 = 15:1, DN = 20:1, D4 = 25:1, EK = 30:1, FA = 40:1, FT = 50:1, GC = 60:1, running up to 10,000:1
RD Series (current format)
- U — RD solid output style
- 20 — center distance, 2.00″
- SL — output arrangement, shaft left (solid left / right / double, or hollow bore)
- 05 — ratio, 5:1
- 56 — input adapter, 56C frame

Winsmith and Grove Gear Size Cross-Reference
Worm gear reducers are sized by center distance, and the industry has largely standardized on the same ladder. That is why a Winsmith unit and a Grove Gear unit of the same center distance are usually talking about the same mechanical envelope.
| Center distance | Winsmith RD Series | Winsmith D-90 Type SE | Grove Gear / Electra-Gear size code |
|---|---|---|---|
| 1.33″ | 13 | 913 | 813 / EL813 |
| 1.54″ | — | — | 815 |
| 1.75″ | 17 | 917 | 818 / EL818 |
| 2.00″ | 20 | 920 | — |
| 2.06″ | — | — | 821 / EL821 |
| 2.375″ – 2.38″ | 24 | 924 | 824 / EL824 |
| 2.62″ – 2.625″ | 26 | 926 | 826 / EL826 |
| 3.00″ | 30 | 930 | 830 / EL830 |
| 3.25″ | — | — | 832 / EL832 |
| 3.50″ | — | 935 | — |
| 4.25″ | — | 943 | 842 / EL842 |
| 5.25″ | — | — | 852 / EL852 |
| 6.00″ | — | — | 860 / EL860 |
Matching center distance is a starting point, not a guarantee. Bolt pattern, output shaft diameter and extension, mounting position, and overhung load still have to be confirmed. Winsmith publishes formal interchange guides for the RD Series against Baldor, Boston, Dodge, Grove, Hub City, and Morse drives — send us the model number you are replacing and we will run the cross for you.
We Also Stock Grove Gear and Electra-Gear
Winsmith is an HBD Industries brand. Grove Gear and Electra-Gear are Regal Rexnord brands. Carrying all three means we can quote the drive your plant already standardized on — or the one that is actually on the shelf when the line is down.
Grove Gear
Cast iron worm gear reducers and high-efficiency helical alternatives, built around the familiar 800-series size codes.
- IRONMAN GR Series — one-piece cast iron worm, sizes 813 through 8100, ratios to 216,000:1
- NH Series — narrow-housing cast iron for tight mounting envelopes
- SS Series — stainless worm and helical-worm for chemical, meat, and food processing
- WASHGUARD — epoxy-coated worm, helical-inline, helical-worm, helical-bevel, and parallel shaft for food, dairy, and bottling
- LeCentric P Series and E Series — helical inline when worm efficiency is costing you horsepower
- HERA — helical-hypoid right angle, up to 90% efficient, a direct high-efficiency swap for worm drives
Electra-Gear
The aluminum-housing worm line within the Grove Gear catalog, carried under the EL series code — lighter, corrosion-resistant, and dimensionally matched to the same 800-series size grid as the cast iron units.
- EL Series — one-piece 356T cast aluminum housing, ten sizes, ratios 5:1 to 216,000:1, ratings to 29 HP
- Single reduction worm, double reduction worm-worm, and double reduction helical-worm arrangements
- Polished finish available for wash-sensitive environments
- Common applications: car wash equipment, conveyors, specialty lifts, packaging machinery
- Same EL8xx size codes as cast iron GR8xx — easy to move between housings without re-engineering the mount

Exporting Winsmith Gearboxes Worldwide
Jealco was founded in 1950 to put US-built industrial goods into the hands of buyers outside the United States. That is still what we do.
We quote in USD with clear Incoterms, handle HS classification and commercial documentation, consolidate gearing with motors, belting, and elevator buckets into a single shipment, and crate for ocean freight. If you are an OEM, plant engineer, or distributor in Latin America, the Caribbean, Africa, or Asia, you do not need a US freight forwarder relationship to buy a Winsmith reducer from us — we already have one.
Winsmith Speed Reducer FAQ
Does Jealco sell Winsmith speed reducers?
Yes. Jealco International supplies Winsmith right-angle worm, helical inline, helical bevel, and planetary gearing, including the RD Series, SE Encore, D-90 Type SE and Type DE, stainless steel washdown units, and the aluminum ALRN and ALSQ lines. Send the model number or the application details to sales@jealco.com and we will confirm availability and pricing.
Who owns Winsmith?
Winsmith is a brand of HBD Industries, Inc. It is headquartered in Springville, New York, and manufactures in Springville and in Flowery Branch, Georgia. It is a separate company from Regal Rexnord, which owns the Grove Gear and Electra-Gear brands — one reason we carry both.
What is the difference between Winsmith and Grove Gear?
They are competing worm gear reducer lines from different manufacturers. Winsmith is an HBD Industries brand; Grove Gear, along with the Electra-Gear aluminum line, belongs to Regal Rexnord. Both use center distance as the primary sizing dimension and both offer NEMA C-face motor inputs, so the two lines frequently compete for the same application. Winsmith's RD Series is specifically built to be dimensionally interchangeable with Grove drives among others.
Which one we recommend depends on stock, lead time, ratio availability, and whether your plant already standardizes on one brand's spare parts.
Can a Winsmith reducer replace my Grove Gear, Boston, Morse, Hub City, Dodge, or Baldor unit?
Often, yes. The Winsmith RD Series is designed to be dimensionally interchangeable with the most commonly installed right-angle drives from Baldor, Boston, Dodge, Grove, Hub City, and Morse, and Winsmith publishes interchange guides for each. Matching center distance alone is not enough, though — bolt pattern, output shaft diameter and extension, mounting position, and overhung load all have to check out. Send us the model number you are replacing and we will run the cross before you buy.
What do the numbers in a Winsmith model number mean?
On a legacy D-90 Type SE unit, the leading 9 identifies the series and the next two digits are the center distance in hundredths of an inch — 926 is a 2.625-inch center distance, 930 is 3.00 inches, 935 is 3.50 inches. The letters that follow describe input style, basic model, number of reductions, shaft arrangement, and motor frame, and the final two characters are a ratio code. On current RD Series units the format is style, center distance, output arrangement, ratio, and input adapter, as in U20SL05-56. The decoder above walks through both.
My Winsmith gearbox is obsolete. Can you still get parts or a replacement?
Usually. Send a clear photo of the nameplate to sales@jealco.com. We will decode the size, ratio, reduction stages, shaft arrangement, and motor frame, then quote either a current Winsmith equivalent or an interchangeable unit from another line we carry if that gets you running sooner.
Do you stock washdown and stainless steel worm gear reducers?
Yes. Winsmith offers stainless SE reducers in 2.00-inch, 2.625-inch, and 3.50-inch center distances with ratios from 5:1 to 360:1, plus stainless conveyor drives and stainless gearmotors. The RD Max variant adds stainless output shafts, IP66 sealing, and food-safety blue plugs. On the Regal Rexnord side we supply Grove Gear SS Series stainless and WASHGUARD epoxy-coated units. For incidental food contact, SE Encore units ship with NSF H1-registered Mobil Glygoyle 460 synthetic lubricant.
Worm gear or helical — which should I specify?
Worm reducers are compact, inexpensive per unit of ratio, quiet, and can be self-locking at high ratios, but efficiency falls as ratio climbs, which shows up on your power bill on drives that run continuously. Helical inline, helical bevel, and helical-hypoid units run substantially more efficiently and are worth the higher purchase price on high-duty-cycle drives. If your application runs 24 hours a day, ask us to price both and compare the operating cost, not just the quote.
Do you export Winsmith gearboxes outside the United States?
Yes — that is our core business, and has been since 1950. We ship to Latin America, the Caribbean, Africa, and Asia, quote with clear Incoterms, handle HS classification and export documentation, and consolidate gearing with motors, conveyor belting, and other equipment into a single crated shipment.
