EP-NMRV063 Worm Gearbox — Heavy-Belt Conveyor & Industrial Agitator Power
The EP-NMRV063 aluminum worm gearbox is the workhorse of Ever Power’s upper compact range — the first model in the NMRV series with a housing large enough to accept both NEMA 56C and the larger NEMA 140TC input flanges, broadening its motor compatibility to cover 1.1 kW drives and above. At 6,2 кг, it remains hand-installable by a single operator while delivering output torques reaching 500 Nm — more than sufficient for loaded inclined belt conveyors, heavy agitator tanks, and agricultural PTO-driven machinery used across regional Australia.
The NMRV063 uniquely offers five output flange configurations (FA, FB, FC, FD, FE) — the widest selection in the NMRV range — with pilot diameters spanning 80 to 130 mm. Combined with a 28 mm primary output shaft diameter and optional 25 mm variant, this makes the NMRV063 a true universal worm gear reducer capable of interfacing with driven equipment across all major industrial standards.

Негізгі ерекшеліктері және инженерлік артықшылықтары
📝 Five Output Flange Configurations
FA through FE cover pilot diameters from 80 to 130 mm — the widest selection in the NMRV range. Engineers can match virtually any driven-machine bolt circle without custom machining, reducing project engineering cost and lead time significantly for Australian OEM machine builders.
⚙ Dual NEMA Input — 56C & 140TC
The NMRV063 is the entry-level NMRV model to accept the NEMA 140TC input flange, enabling direct mounting of larger 0.75–1.5 kW motors commonly used in Australian agricultural and mining ancillary equipment — without the need for an uprated NMRV075 housing.
📈 500 Nm Output at 6.2 kg
Specific torque output of approximately 80 Nm/kg. For conveyor designers accustomed to heavy cast iron reducers, this represents a 60–70% weight saving with equivalent or superior torque output — directly reducing structural steel requirements in conveyor frames.
🔥 High Radial Load Capacity — 5,595 N
The NMRV063’s oversize output shaft bearings support up to 5,595 N radial load — enabling direct chain sprocket or belt pulley mounting without intermediate bearing pedestals. This is critical for grain auger drives and quarry conveyor tail-end drives operating in remote Australian locations.
♨ Quiet Bronze Worm Mesh
The phosphor-bronze wheel meshes against a hardened steel worm to produce smooth, low-vibration output — typically under 68 dB(A) at full load. In food processing and grain handling facilities, lower noise reduces workplace fatigue and improves compliance with SafeWork Australia noise exposure limits.
