EP-NMRV050 Aluminium Worm Reducer – Light-to-Medium Duty Crossover
The EP-NMRV050 bridges the gap between light-duty NMRV040 and medium-duty NMRV063 applications. At 3.5 kg with 50 mm centre distance and Ø25 mm output shaft, it handles output torques up to 89 Nm – sufficient for single-lane packaging conveyors, water treatment paddle drives, and food processing belt systems that exceed the NMRV040 capacity but do not yet require the bulk of the NMRV063. The Ø25 mm output shaft matches standard Australian industrial coupling and sprocket bore sizes directly without adaptor sleeves. IEC motor frames from 56 to 80 connect directly via B5 or B14 flange – adding frame 80 compatibility that the NMRV040 does not offer. Four output flanges FA, FB, FC, and FD provide versatile direct machine mounting. The NMRV050 also serves as the output stage for NMRV030/050 double-stage combinations reaching 4800:1, and as a pre-stage for NMRV110 in extreme-ratio configurations up to 5000:1.

✓ Основні характеристики та переваги
Matches the most common Australian coupling and sprocket bore size for medium-duty industrial drives. Direct fit without adaptor sleeves – reducing installation cost and potential misalignment.
Adds IEC frame 80 compatibility that the smaller NMRV040 does not offer – extending the input power range to 0.75 kW for medium-duty applications without stepping to the heavier NMRV063.
Light enough for one-person installation in all mounting orientations. Aluminium housing dissipates operating heat efficiently for continuous duty at up to 40°C ambient without supplementary cooling.
Pairs with NMRV030 as pre-stage reaching 4800:1, with NMRV110 as output stage reaching 5000:1, and with PC063/PC071 helical pre-stages for higher-efficiency extended ratio combinations.
⚙ Галузеві застосування
Paddle drives, flocculator mechanisms, and dosing conveyors in municipal and industrial water treatment plants. Aluminium resists the humid, chemically aggressive plant environment that corrodes uncoated cast iron within months.
Single-lane product conveyors, labelling machines, and shrink-wrap infeed drives. Ø25 mm output directly coupled to conveyor drive sprockets without bore modification.
Corrosion-resistant aluminium worm gearbox for meat processing, dairy, and bakery belt conveyors requiring 40-80 Nm output torque. Handles daily CIP washdown cycles.
Low-speed drives for dosing pumps, small agitators, and ventilation fan mechanisms where 89 Nm at 0.75 kW meets the torque requirement with margin.
⚙ Керівництво з вибору та монтажних положень
Select the NMRV050 when your application requires output torque between 22 Nm and 89 Nm at input power up to 0.75 kW. Step up to the NMRV063 at 167 Nm maximum for heavier loads. The NMRV040 at 53 Nm maximum is more cost-effective for lighter applications. The NMRV050 is the first NMRV size offering IEC frame 80 compatibility.

⚖ Aluminium vs Cast Iron Comparison
The NMRV050 at 3.5 kg replaces cast iron equivalents weighing 6-8 kg – a significant advantage for field installation, shipping cost, and overhead mounting applications. Aluminium also provides superior corrosion resistance for water treatment and food processing environments.
