EP-NMRV130 Flagship Heavy-Duty Aluminium Worm Reducer – Product Overview
の EP-NMRV130 is the largest and most powerful unit in the NMRV aluminium worm reducer series – delivering up to 1596 Nm output torque from input powers up to 9.2 kW. At 48 kg, it represents a significant weight saving over the 70+ kg cast iron equivalents at this torque level, making overhead, wall-mount, and remote-site installations substantially more practical. The 130 mm centre distance and Ø45 mm output shaft handle the heaviest conveyor drives, large industrial agitators, and construction equipment mechanisms in the NMRV range. IEC frames 80 to 210 connect directly. Compatible with PC090 helical pre-stage for extended ratios. Also serves as output stage for NMRV063/130 double-stage combinations reaching 5000:1 with output torques up to 2430 Nm – the highest torque achievable in the entire NMRV aluminium range.

✓ 主な機能とメリット
The highest torque available in the entire NMRV aluminium series. Competes directly with cast iron reducers at this performance level – at 30% less weight.
Accepts the largest standard IEC motors directly via B5 or B14 flange for input powers up to 9.2 kW. The complete heavy-industrial motor range in one aluminium housing.
30% lighter than the cast iron equivalent. Enables overhead and wall-mount installation at heavy-duty torque levels without the structural reinforcement that 70+ kg cast iron requires.
NMRV063 as pre-stage plus NMRV130 as output reaches extreme ratios with output torques up to 2430 Nm – the highest double-stage torque in the entire NMRV range.
⚙ 産業用途
Auxiliary drives for construction hoists, crane traversal mechanisms, and concrete plant equipment. 1596 Nm handles heavy mechanical loads. 48 kg enables mobile equipment installation.
Main drives for loaded belt conveyors in mining, quarrying, recycling, and timber processing. 130 mm centre distance handles sustained high-torque running at industrial speeds.
Industrial mixing drives for chemical reactors, water treatment clarifiers, and mineral processing vessels. Ø45 output matches heavy agitator coupling bore sizes.
Main drives for palletisers, heavy indexing platforms, industrial gate actuators, and dam sluice mechanisms requiring torques above 900 Nm in continuous service.
⚙ 選定ガイドと取り付け位置
The NMRV130 covers output torque from 334 Nm to 1596 Nm at input powers up to 9.2 kW. This is the largest NMRV frame available. For torques above 1596 Nm in aluminium, use the NMRV063/130 double-stage combination delivering up to 2430 Nm. For even higher torques, transition to the Ever Power WP cast iron worm reducer series.

★お客様の声
“NMRV130 on our quarry conveyor head drives. 48 kg – our crew installs with a manual hoist. 1200 Nm continuous running for 16 months without any issues. Very impressed with reliability.”
Gary T. – Pilbara Aggregates (Australia)
“NMRV063/130 double-stage on our dam sluice gate actuators. 2400 Nm at 5000:1 ratio. Completely eliminated the multi-reducer chain drive we previously used. Much cleaner installation.”
Jean-Luc D. – Hydropower Savoie SA (France)
“Replaced 6 cast iron reducers on our chemical vessel agitators. NMRV130 saved 132 kg total on the vessel platform. Our engineers approved lighter support steelwork as a result.”
