WPEDX Flange-Mounted Dual Output Double Speed Worm Gear Reducer — Motor-Direct Bilateral Synchronisation at Ultra-High Ratios
The WPEDX represents the peak integration of the WPE double-speed family — combining three elements that individually define separate product categories: an IEC motor flange (eliminating the input coupling), a two-stage worm cascade (delivering 1/200–1/900 ratios), and dual synchronised output shafts (providing mechanically exact bilateral drive). No single-stage product can match its ratio range; no non-dual-output product can provide bilateral synchronisation; no indirect-drive product eliminates the coupling. The WPEDX does all three simultaneously.
This makes the WPEDX the definitive solution for heavy-duty synchronised packaging lines, wide-belt industrial drives, and bilateral printing press auxiliaries requiring motor-direct ultra-high ratio bilateral drive in a single compact unit. Available in 9 size groups, motors 0.12–5.5 kW, ratios 1/200–1/900, shaft directions A–C. Über Ever-power | Get a Quotation

Product Structure — Motor Flange + Two-Stage Cascade + Dual Output

The WPEDX combines three structural elements in one casting: an IEC motor flange at the first-stage input, a two-stage worm cascade delivering ultra-high reduction, and the second-stage worm wheel shaft bored through both sides of the housing for equal-length dual output. The wider housing provides four-bearing support for the extended output shaft, maintaining full torque capacity under asymmetric loading.

| Stages | Two worm-and-wheel pairs in series; ratio 1/200–1/900 |
| Output | Dual solid shafts, keyed to second-stage worm wheel — zero speed differential |
| Housing | FC25 cast iron; wider body for dual output bearing bores |
| Bearings | 6 bearings total: 2 per worm shaft (both stages) + 2 on output shaft ends |
| Directions | 3 motor flange positions: A, B, C |
✅ Key Features & Benefits
Motor-Direct + Two-Stage + Dual Output — Triple Integration
The WPEDX is unique in simultaneously providing: no input coupling (IEC flange), extreme reduction ratios 1/200–1/900 (two-stage), and mechanically exact bilateral synchronisation (dual output). No other single product achieves all three — and the WPEDX does it in one cast iron unit. Keywords: motor-direct dual output double speed worm gearbox, IEC flange bilateral two-stage reducer.
Mechanically Exact Bilateral Synchronisation at Ultra-High Ratios
Both output shafts are keyed to the second-stage worm wheel — zero speed differential is guaranteed mechanically at any combined ratio from 1/200 to 1/900. For packaging lines, paper handling systems, and printing auxiliaries operating at very low synchronised bilateral speeds, this is the definitive solution.
Eliminates Three Separate Components
One WPEDX replaces: (1) a motor coupling, (2) a two-stage gearbox, (3) a bilateral synchronisation drive. For machine builders, eliminating these three components simplifies the BOM, reduces assembly time, and removes three potential failure/maintenance points from the machine — a compelling total cost of ownership argument.
Precision Two-Stage Output at Very Low Speeds
Both worm pairs ground to ISO 1328 Grade 7. The resulting output — at combined ratios like 1/600 or 1/900 — is smooth, uniform, and free from gear-induced velocity variation. For paper handling and film processing applications, this output quality is essential for product consistency.
Rugged FC25 Cast Iron for Industrial Environments
The wider two-stage FC25 cast iron housing with six-bearing support handles asymmetric bilateral loads confidently, ensuring long bearing and seal life even when one output shaft carries a heavier load than the other.
Full 9-Size Range — 0.12 to 5.5 kW Motors
Nine size groups cover motor powers from 0.12 kW (light bilateral positioning drives) to 5.5 kW (heavy bilateral industrial drives), providing the broadest application coverage for motor-direct dual-output two-stage drives available in a single standardised product family.
Industry Applications
The WPEDX is specified wherever motor-direct ultra-high ratio bilateral synchronised drive in a single unit is the design requirement:
Heavy Packaging LinesPallet wrapping machine drive systems, heavy strapping machine bilateral drives, and large-format case sealing systems requiring ultra-low bilateral synchronised speed from motor-direct two-stage drives.
Printing Press AuxiliariesWide-format printing press ink roller bilateral drives, paper handling system drives, and print finishing machine slow-speed bilateral mechanisms requiring 1/400–1/900 ratio motor-direct dual drive.
Film & Foil ProcessingWide-format metal foil rolling mill bilateral drives, plastic film stretching system slow-speed bilateral drives, and packaging film laminator bilateral roll drives.
Wide Textile MachineryWide fabric winding machine bilateral drives, heavy carpet tufting machine auxiliary bilateral drives, and industrial webbing weaving machine slow-speed bilateral systems.
Heavy Test EquipmentIndustrial bilateral loading frames, high-torque dynamometer loading drives, and precision bilateral torque application systems for material testing and quality control.
Industrial AutomationHeavy-duty bilateral indexing table drives, large-format CNC lathe bilateral tail-stock drives, and industrial bilateral positioning systems requiring motor-direct ultra-high ratio bilateral synchronisation.
Quality Control & Certification
ISO 9001:2015 & CE
Full ISO 9001:2015 QMS. CE Declaration of Conformity per shipment. Three dimensional verifications on every WPEDX: IEC flange concentricity (≤0.05 mm TIR), both output shaft run-outs (≤0.05 mm TIR each), and output shaft keyway symmetry check.
Triple Verification Test
The WPEDX undergoes three simultaneous verifications during the 45-minute load test: (1) IEC flange concentricity, (2) bilateral output shaft run-out at both ends, (3) torque balance verification — both shaft ends must produce equal torque within ±3% at rated load. This ensures motor fit, ratio performance, and bilateral symmetry are all confirmed in one test.
Material Standards
Housing: FC25 cast iron (≥250 MPa). Both worm shafts: 20CrMnTi (≥58 HRC). Both output shaft extensions machined from same billet, heat-treated together — matched properties. Full material certs on request for paper and film industry compliance documentation.

⭐ Customer Reviews
“We use WPEDX units on our heavy pallet wrapping system bilateral drives. The 1/600 ratio gives us the ultra-slow wrapping speed our customers need, and the IEC flange motor mounting plus bilateral synchronisation makes the machine both simpler and more reliable than our previous solution with a separate gearbox and sync chain. Excellent product from Ever-power.”
Andrew M., Machine Design Engineer
Packaging Machinery OEM, Victoria, Australia
“We integrate WPEDX-80/135 units at 1/800 ratio into our wide-format printing press slow-advance drives. The triple integration — IEC flange, 1/800 ratio, bilateral synchronisation — eliminates three separate components from our machine BOM. Output smoothness at 1/800 is excellent — essential for print quality. Consistent quality from Ever-power.”

❓ Frequently Asked Questions
How does the WPEDX differ from the WPEX (non-motor-direct)?
The WPEX has a standard solid input shaft requiring an external coupling to the motor. The WPEDX has an IEC motor flange allowing direct motor attachment without a coupling. Both provide two-stage dual synchronised output. Choose WPEX when you have an existing coupling arrangement; choose WPEDX when you want to eliminate the input coupling entirely for the simplest possible motor-to-bilateral-output drive chain.
Can the WPEDX be used with a variable-speed drive (VSD)?
Yes — the WPEDX is VSD compatible. For continuous operation at low VSD frequencies (below 30 Hz), note that TEFC motor cooling reduces proportionally with speed. For high-load low-speed VSD duty, consider the WPEDXS variant (if available in your required size) or contact us about duty cycle thermal assessment for your specific VSD profile.
What is the maximum combined output torque of the WPEDX?
The combined output torque from both shaft ends must not exceed the rated output torque for the selected size group and ratio. At rated 1500 r/min input, size 155-250 at ratio 1/900 delivers approximately 6,050 Nm combined. Each shaft end provides ~3,025 Nm under symmetric loading. Contact our engineers with your motor power and required ratio for a precise calculation.
Can the WPEDX output shaft extensions be different lengths (asymmetric)?
By default, E₁ = E₂ (equal extensions). Custom asymmetric extensions are available for OEM customers whose machine requires the gearbox to be positioned off-centre between the two drive points. Minimum order quantity and tooling charges apply — contact us with your required E₁ and E₂ dimensions.
What is the relationship between WPEDX and the smaller WPDX (single-stage)?
The WPDX (single-stage) provides IEC flange + dual output with ratios 1/5–1/60. The WPEDX (two-stage) provides the same features with ratios 1/200–1/900. If your application requires bilateral synchronisation at ratios within the 1/5–1/60 range, the WPDX is the appropriate selection. If you need bilateral synchronisation at ratios beyond 1/60, the WPEDX is the only available solution.
