EP-NMRV040 — The Mid-Range Industrial Workhorse<\/h2>\n

When an application demands more muscle than the NMRV030 can provide yet installation space, weight budget, or cost constraints make a large-frame reducer impractical, the EP-NMRV040<\/strong> aluminium worm gearbox is the natural answer. With a 40 mm centre distance and a maximum input power of 0.55 kW, it bridges the gap between micro-reducers and full-size industrial units, unlocking output torques up to 3,118 N·m while keeping the housing weight below 3 kg. Industries from conveyor system design to agricultural machinery OEM and print-line automation have adopted the NMRV040 as a standard platform because of its wide IEC motor-frame compatibility — accepting 56B5, 63B14, 71B5, and 71B14 flanges — and because its six mounting positions eliminate the need for bespoke frame modifications. The precision-ground worm and phosphor-bronze wheel combination minimises backlash and delivers smooth, low-noise operation at continuous duty, making the NMRV040 equally suited to precision indexing tables and robust grain-handling conveyors.<\/p>\n
