EPNMRV110 Worm Gearbox — Product Overview
The EPNMRV110 steps firmly into heavy-duty territory with a 110 mm centre distance, 35 kg housing, and rated output torque up to 855 Nm. This single-stage worm gearbox is specified by Australian construction, infrastructure, and heavy-industrial OEMs for concrete batching-plant agitators, cable-drum winches, hoist drives, quarry screening units, and heavy stirrer-mixer drives. Unlike the smaller EPNMRV090, the EPNMRV-110 supports 140TC, 180TC, and the larger 210TC NEMA motor flanges — necessary once motor powers pass 3 kW and the bolt-pattern reach of the smaller flanges becomes a mechanical-strength bottleneck. With eight standard ratios from 7.5:1 to 50:1, a 1.625″ output shaft and matching hollow bore, plus a 9,232 N radial-load rating, the EPNMRV110 is the reducer Australian project engineers reach for when cast-iron alternatives would add cost, freight, and crane-lift complexity without delivering a measurable performance advantage.
Fokus aplikasi utama: concrete batching plants and heavy-duty hoists di dalam Heavy Construction & Infrastructure sektor di seluruh pasar industri Australia.

Reinforced Casing for Impact Loads
Thicker-wall EPNMRV110 housing plus upsized output-shaft bearings handle start-stop shock loads delivered by concrete-mixer reversals and crushed-stone feeder screws.
Large-Frame NEMA Flange Compatibility
140TC, 180TC, and 210TC flanges accept motor powers from 1.1 kW to 5.5 kW — sized for the three-phase motors common on Australian construction sites.
Eight Field-Proven Ratios
Ratios from 7.5:1 to 50:1 provide the right speed-torque curves for hoist drives, winches, and heavy stirrer drives — without excess over-reduction.
Large Surface-Area Cooling Fins
Extended aluminium finning on the EPNMRV-110 extracts heat during continuous-duty operation in enclosed site huts and covered batching plants.
9,232 N Radial Load Capacity
Carries overhung sprocket and drum-wind loads without the need for external pillow-block bearings — saving both cost and installation time.
Every EPNMRV110 unit is machined, assembled and factory-tested before shipment
Industry Applications — Where the EPNMRV110 Excels
The EPNMRV110 worm gearbox has been specified into thousands of Australian installations across these five primary industry segments. Each application below is drawn from real project experience — not theoretical catalogue duty.
Pertambangan & Pengolahan Mineral
The EPNMRV110 drives heavy feed conveyors at primary crushers, screen-deck tensioning mechanisms, and large flotation-cell agitators. Its 855 Nm rated torque and 9,232 N radial-load capacity make it a reliable heavy-duty worm gearbox for mineral processing applications.
Heavy Material Handling & Logistics
Port bulk-handling reclaimer boom-slew drives, long-haul conveyor head pulleys, and heavy pallet-stacker hoist reducers use the EPNMRV-110 in applications where motor powers up to 5.5 kW are required.
Pengolahan Lingkungan & Air
Large municipal clarifier centre drives in Australian metropolitan water-treatment plants, heavy belt-press pinch rollers, and sludge-thickener rake drives specify the EPNMRV110 for its high torque and corrosion-resistant aluminium construction.
Pertanian & Produksi Primer
Large feed-mill pellet-press auxiliary drives, cotton-gin auxiliary reducers, and grain-terminal ship-loader auxiliary gearboxes use the EPNMRV-110 where its high continuous-torque capacity is essential.
Pengolahan Makanan & Minuman
Large-capacity dough mixers, meat-abattoir rail drives, and multi-head bottling carousel mains reducers use the EPNMRV110 in heavy-duty food-processing environments.
Panduan Seleksi & Perbandingan
Sizing the EPNMRV110 for Your Application
Penentuan ukuran yang tepat dimulai dengan dua parameter inti: yang dibutuhkan torsi keluaran (M2) dan diwajibkan daya masukan (P1). Follow this three-step process when selecting the EPNMRV110:
- Identifikasi kecepatan keluaran yang dibutuhkan (n2) — this determines your reduction ratio (i). The EPNMRV110 offers ratios from 7.5:1 to 50:1.
- Hitung torsi yang dibutuhkan dengan faktor layanan. — kalikan torsi teoritis dengan faktor layanan yang sesuai (1,0 untuk beban konstan, 1,5–2,0 untuk beban kejut, 2,0–2,5 untuk beban bolak-balik).
- Periksa kapasitas beban radial pada poros keluaran. — overhung sprocket or pulley loads must not exceed 9232 N measured at the shaft midpoint for the EPNMRV110.

Referensi Posisi Pemasangan (B3 / B6 / B7 / B8 / V5 / V6)
The EPNMRV110 supports six standard mounting orientations. Each orientation affects the required lubrication charge and plug positioning — specify the correct orientation at time of order:
| Posisi | Orientasi | Pengisian Oli Khas |
|---|---|---|
| B3 | Poros horizontal, dudukan kaki (standar) | Pengisian reservoir standar |
| B6 | Poros horizontal, pemasangan di dinding sebelah kiri | Pengisian reservoir standar |
| B7 | Poros horizontal, pemasangan di dinding sebelah kanan | Pengisian reservoir standar |
| B8 | Poros horizontal, dudukan kaki terbalik | Isi standar + 10% |
| V5 | Poros vertikal ke bawah | Pengisian meningkat (+25%) |
| V6 | Poros vertikal ke atas | Pengisian meningkat (+25%) |
Pengisian oli yang tidak tepat untuk orientasi pemasangan tertentu adalah penyebab utama keausan roda gigi cacing yang prematur dalam 1.000 jam pemakaian pertama — tentukan dengan benar saat pemesanan untuk menghindari hal ini.
EPNMRV110 (Aluminium) vs Traditional Cast-Iron Worm Reducers
Pembeli di Australia secara konsisten memilih reduktor cacing berbahan aluminium dibandingkan unit lama berbahan besi cor karena lima alasan yang dapat diukur:
| Atribut | EPNMRV110 Aluminium | Besi Cor Tradisional |
|---|---|---|
| Berat (ukuran setara) | 35.0 kg | ~98.0 kg (approx 2.5–3× heavier) |
| Ketahanan Korosi | Sangat baik — aluminium membentuk lapisan oksida pasif. | Membutuhkan perawatan cat secara aktif. |
| Disipasi Panas | Konduktivitas termal 3–4 kali lebih baik | Terbatas — hanya mengandalkan luas permukaan saja |
| Penanganan Instalasi | Pemasangan oleh satu orang dalam banyak kasus | Biasanya membutuhkan alat bantu angkat meskipun ukurannya kecil. |
| Biaya Pengiriman | Lebih rendah — pengurangan berat kargo udara | Biaya pengiriman udara per unit yang lebih tinggi |
| Titik Harga | Umumnya 15–30% lebih rendah daripada besi cor | Harga premium untuk barang lama |
Frequently Asked Questions — EPNMRV110
Answers to the questions most commonly raised by Australian engineers and procurement buyers specifying the EPNMRV110 worm gearbox.
❓ Can the EPNMRV110 drive a cable-drum winch continuously?
Continuous-duty winch applications require careful thermal sizing. The EPNMRV-110 rated 855 Nm output is achievable continuously provided motor input is matched to the catalogue curve and ambient stays below 40 °C. For duty cycles heavier than 60% in an enclosed site hut, specify the optional fan-cooling unit.
❓ Which NEMA flanges does the EPNMRV110 accept?
The EPNMRV-110 accepts 140TC, 180TC, and 210TC NEMA motor flanges — covering three-phase motor powers from approximately 1.1 kW up to 5.5 kW at 1400 rpm input. IEC 90B5, 100B5, and 112B5 frames are also supported. 56C NEMA is not available at this size.
❓ What is the EPNMRV-110 output shaft diameter?
The standard output shaft diameter is 1.625″ (41 mm) for both solid-shaft and hollow-bore variants. The shaft is parallel-keyed per ANSI B17.1; metric keyways (8×7) are also available as a factory option on the hollow-bore variant. Specify at order to ensure correct key supply.
❓ Can the EPNMRV110 be wall-mounted?
Yes — both B6 (wall-mount, horizontal shaft left) and B7 (wall-mount, horizontal shaft right) are supported. At 35 kg installed weight, we strongly recommend mounting to a cast or welded-steel backing plate rather than thin sheet metal. Confirm wall substrate rating before installation.
❓ What oil change interval should I plan for?
Factory synthetic oil charge is rated for 15,000–20,000 service hours under normal duty. In high-ambient Australian mining or construction sites routinely exceeding 45 °C, plan a mid-life oil replacement at 10,000 hours using the same synthetic PAG spec. Oil drain and fill plug positions are clearly marked on the housing.
❓ Is the EPNMRV-110 suitable for high-humidity coastal installations?
Yes, with the marine-grade paint option. The aluminium body itself resists atmospheric corrosion, but the steel fasteners and input shaft need protection in coastal air. We include stainless M10 fasteners and a sealed input-shaft boot as part of the marine-grade spec.
