Description
The DZ Series worm gear reducer solves a specific engineering problem: delivering IEC B5 motor flange input and solid shaft output in a housing that is dimensionally shorter than the WDZ or standard WD series at the same power rating. The DZ achieves this compact form by redesigning the body geometry — the combined AB dimension replaces the separate A and B convention of the W family, producing a housing that is more axially compact along the output shaft axis while retaining full IEC flange motor direct-coupling on the input face. No input coupling, no coupling guard, no motor bracket; the motor flanges directly and the output shaft connects to the driven load via a standard coupling or sprocket. For Australian OEM machinery builders and plant engineers in Sydney, Melbourne, Brisbane, Perth, and Adelaide who need the clean IEC motor integration of a flange-mount design in a machine bay too narrow for the W-series or WDZ housing depth, the DZ provides the right answer. Covering sizes 50–135, input powers 0.18–3.0 kW, and ratios 10:1–60:1. Manufactured to ISO 9001:2015, designed per AGMA 6034, supplied by Ever-Power Worm Gear Reducer Co., Ltd. (Australia), 27 Harley Crescent, Condell Park NSW 2200.

DZ Housing Geometry Note
The DZ uses combined AB dimensions (not separate A and B). AB = combined centre distance and body depth in the output shaft axis direction. LL = overall length including IEC flange and output shaft. CC = body width perpendicular to output shaft.

DZ vs WDZ vs FCWD — Understanding the Compact Housing Advantage
DZ Series — Compact Housing Profile
| Feature | DZ (Compact) | WDZ (W-family) | FCWD (W-class output) |
|---|---|---|---|
| Input | IEC B5 flange | IEC B5 flange | IEC B5 flange |
| Output | Solid shaft | Solid shaft (W-class) | Solid shaft (W-class) |
| Housing depth (AB) | 87–183 mm — compact | 84–240 mm — W-convention | 165–442 mm — W-class full |
| Size range | 50–135 (up to 3.0 kW) | 50–175 (up to 7.5 kW) | 50–155 (up to 5.5 kW) |
| Best for | Narrow machine bays, compact OEM designs | W-convention legacy machines | High OHL solid shaft, legacy W upgrade |
The DZ’s compact housing is achieved by redesigning the body geometry around the combined AB dimension — the housing body depth along the output shaft axis is compressed compared with the WDZ by merging the worm shaft and output shaft bearing spans into a tighter envelope. This makes the DZ approximately 15–30% shorter in the output shaft direction than the WDZ at equivalent power ratings, allowing installation in machine bays where the WDZ’s full depth would not fit. The trade-off is a slightly lower maximum overhung load rating at the output shaft compared with the W-class output shaft of the FCWD — the DZ is the correct specification when compactness is the primary requirement and output shaft overhung load is within standard ratings.
How to Select the DZ — When Compactness Wins
- DZ or WDZ? Choose DZ when: (a) machine envelope constrains the housing depth along the output shaft axis; (b) output shaft overhung loads are within standard DZ ratings (light-to-medium sprocket or coupling loads); (c) sizes 50–135 and up to 3.0 kW cover the application. Choose WDZ when: (a) the W-series dimensional footprint is required for legacy machine compatibility; (b) output shaft W-class bearing span is needed for higher overhung loads; (c) sizes up to 175 at 7.5 kW are required.
- Confirm IEC motor frame: DZ IEC flange (LZ dimension) accepts standard IEC B5 frames. Typical: DZ-60 → 63B5; DZ-80 → 80B5; DZ-100 → 90B5, 100B5; DZ-120/135 → 112B5. Confirm motor frame designation before ordering.
- Calculate torque and select frame size: Apply SF 1.25–1.5 to design torque. DZ rated output torques are consistent with the compact housing design — request the full torque table from Ever-Power for your ratio and frame size.
- Check output shaft coupling: DZ output shaft dimensions (Ø and keyway) follow the compact DZ convention — confirm coupling hub bore matches the DZ shaft Ø for your chosen frame before ordering.

DZ Applications — Compact OEM Drives in Australian Industry
- Compact packaging machine drives (Sydney, Melbourne): DZ at sizes 60–100 for carton erectors, label applicators, and date-coder drives in packaging machinery where the machine frame bay depth is a hard constraint — the DZ’s shorter AB dimension allows the motor-plus-reducer assembly to fit where the WDZ would protrude beyond the machine guard envelope.
- OEM conveyor and material handling (Brisbane, Perth): DZ at sizes 70–120 on in-line conveyor drives for Australian distribution centres and food processing facilities where machine-to-machine spacing is minimised and every millimetre of drive assembly depth is a design constraint.
- Textile and web processing (Melbourne, Geelong): DZ at sizes 60–100 on web tension control and fabric guide roll drives in compact machine frames where the IEC motor direct mount saves installation time and the short housing depth allows tight station spacing.
- Agricultural and irrigation equipment (QLD, SA, WA): DZ at sizes 50–80 on compact pump and valve actuator drives in portable and towed equipment where the reduced housing depth lowers overall machine profile and weight.

What Australian Customers Say About the DZ Series
“DZ 80 on our Sydney packaging machine label applicator drives. The WDZ was 28 mm too deep for our machine guard slot — the DZ fit with 3 mm to spare. IEC motor direct mount, self-locking at 30:1 holds position between labels. 18 months running perfectly.”
— Tony K., OEM Design Engineer, Sydney NSW
“Specified DZ 100 for our Melbourne conveyor drives at 1.5 kW — the short AB dimension let us reduce machine-to-machine spacing by 120 mm on a 12-station line. That’s significant in a tight facility. IEC 90B5 motor flanges directly, clean installation, zero alignment tools.”
— Jennifer K., Facility Engineer, Melbourne VIC
“DZ 70 on our Brisbane compact food conveyor drives. Fits perfectly where the WDZ didn’t. Motor flanges on, coupling to driven sprocket, done. 4 stars only because the DZ tops out at 3.0 kW — for our larger drives we still need WDZ. Within its range it’s excellent.”
— Nathan B., Production Engineer, Brisbane QLD
“DZ 60 for compact pump actuator drives on our WA irrigation equipment — the short housing reduces towed implement profile. 0.37 kW 63B5 motor flanges directly. At 12 kg, easy field installation without tools. Self-locking at 40:1 means no secondary brake required.”
— Terry M., Irrigation Engineer, Geraldton WA
