EP-NMRV050 — Stepping Up to Heavy-Duty Worm Gear Performance<\/h2>\n

The EP-NMRV050<\/strong> represents the first genuinely heavy-duty entry in Ever Power’s NMRV aluminium worm gearbox range. With a 50 mm centre distance, it accepts up to 1.1 kW input power and develops up to 4,280 N·m output torque at 100:1 ratio — nearly 37% more than the NMRV040 — in the same die-cast aluminium architecture. This makes the NMRV050 the default choice for food processing conveyor drives, industrial mixer agitators, heavy packaging machinery, and agricultural grain-handling equipment where a compact but powerful aluminium worm gear reducer must coexist with demanding duty cycles. A key differentiator is its expanded IEC flange range — accepting 63B5, 63B14, 71B5, 71B14, and 80B14 motor flanges — enabling seamless integration with standard motors from 0.12 to 1.1 kW. The NMRV050 also introduces a larger 25 mm output bore, improving torque transmission reliability for shaft-mount applications on high-inertia loads.<\/p>\n
