EP-NMRV030 — Versatile Mid-Micro Power Transmission
دی EP-NMRV030 worm gearbox steps up from the NMRV025 with a 30 mm centre distance and a higher rated input power of 0.18 kW, making it the preferred choice for applications that need more torque than a micro-reducer can deliver while still demanding a compact, lightweight footprint. Across conveyor feeder drives, agricultural equipment, water-treatment valve actuators, and small packaging line components, the NMRV030 delivers up to 1,367 N·m output torque — a substantial capacity for its physical size. The die-cast aluminium housing resists the humid coastal conditions prevalent along Australia’s manufacturing corridors, and the integrated IEC input flanges (56B14, 63B14, 63B5) accommodate the most common motor frames without adaptors. Unlike the NMRV025, the NMRV030 introduces a wider range of IEC connections, giving design engineers more motor-sourcing flexibility for cost-competitive projects.

✅ Core Features & Engineering Benefits
📈 Enhanced Torque Density
The NMRV030 delivers up to 1,367 N·m — a 36% torque increase over the NMRV025 — from a housing weighing under 1.5 kg. Ideal for weight-sensitive platforms such as mobile automation carts.
🕵 Wider IEC Flange Range
Three IEC input flange options (56B14, 63B14, 63B5) give procurement engineers more motor-sourcing flexibility, reducing dependency on a single motor supplier and enabling cost optimisation.
◈ Precision-Ground Worm Shaft
The 20CrMnTi case-hardened and precision-ground worm shaft paired with a phosphor-bronze wheel achieves low backlash and smooth power transfer, critical for positioning and dispensing conveyor applications.
🚫 Leak-Free Sealed Design
Double-contact lip seals on all rotating shafts prevent oil weeping in any mounting orientation — essential for overhead or inverted installations.
🌞 Efficient Thermal Management
External cooling fins increase surface area by over 40% compared to a flat-sided casing, reducing operating temperature rise by up to 15°C versus cast-iron equivalents.
🏭 Industry Applications
🌿 Agricultural Equipment
Compact worm gear reducer for seed dispensers, auger feeds, and irrigation gate actuators. IP54 sealing and aluminium casing withstand dusty outdoor Australian farm environments.
💧 Water Treatment
Worm gear speed reducer for slow-speed valve actuators, dosing pump drives, and filter screen rotation in water treatment facilities where corrosive atmospheres demand a non-ferrous housing.
⚙ Industrial Conveyor Drives
Worm gear reduction gearbox for light-duty belt conveyors in warehousing, parcel sorting, and electronics assembly — precise speed control at low output RPM.
📦 Packaging & Labelling Lines
Worm gearmotor configuration for label applicators, capping heads, and product-rotation turntables requiring smooth low-speed torque delivery on continuous 16–24-hour production shifts.
🔎 Selection Guide & Shaft Dimensions
- Calculate required output torque: M2 = 9550 x P x efficiency / n2.
- Apply service factor: multiply by fs (Type A=1.0–1.2, B=up to 3, C=up to 10).
- Confirm IEC flange size: 56B14 for micro motors, 63B14/63B5 for 0.12–0.18 kW frames.
- Select output shaft type: hollow bore, DZ solid, or F/FL flange as required.

❓ Frequently Asked Questions — EP-NMRV030
How does the NMRV030 differ from the NMRV025?
The NMRV030 has a 30 mm centre distance versus 25 mm, delivering 36% higher maximum output torque (1,367 vs 1,006 N·m) and higher input power (0.18 vs 0.06 kW). It also offers three IEC input flange options compared to two on the NMRV025, accepting 63B5/B14 in addition to 56B14.
Can the NMRV030 operate continuously for 24 hours?
Yes, provided rated torque is not exceeded and ambient temperature stays within -10°C to +40°C. Use service factor fs ≥ 1.25 for 24-hour operation. Oil bath lubrication supports continuous duty for up to 10,000 operating hours.
What is the standard output bore diameter?
The NMRV030 standard hollow output bore is 18 mm (H7) with a 5 mm keyway. DZ solid shaft is 14 mm diameter h6 as standard.
Is it suitable for outdoor agricultural use in Australia?
The NMRV030 is rated IP54 and its aluminium housing withstands Australian coastal and rural conditions. IP65 available on request for high-pressure washdown environments.
What lubricant is pre-filled and when should it be changed?
Factory-filled with ISO VG 220 mineral gear oil. First change at 300–500 hours; then every 5,000 hours or annually. Synthetic lubricant extends intervals to 8,000–10,000 hours.
⭐ کسٹمر کے جائزے
★★★★★
“We fitted the NMRV030 on our seed-dispenser drive chain. After one full planting season — over 800 hours in dusty paddock conditions — the seals are intact, no oil loss detected, and the unit runs as quietly as day one.”
Brett W. — Equipment Manager, Grain Farm 🇦🇺 Australia (Queensland)
★★★★★
“Our water treatment plant uses six NMRV030 units on slow-moving filter screen drives. The aluminium housing resists the chlorinated atmosphere perfectly — we previously lost cast-iron reducers to corrosion within 18 months.”
Carlos M. — Maintenance Supervisor, Water Utility 🇨🇱 Chile
★★★★☆
“Quick delivery and exact dimensions as per the drawing. We integrated eight NMRV030 units into a packaging turntable system and the line throughput improved noticeably due to consistent low-speed torque delivery.”
Piotr N. — Systems Integrator, Packaging OEM 🇵🇱 Poland
