EP-NMRV150 — Flagship Maximum-Torque Aluminium Worm Gearbox<\/h2>\n

The EP-NMRV150<\/strong> is the crown jewel of Ever Power’s NMRV aluminium worm gearbox series. At a 150 mm centre distance with 15 kW maximum input power, it delivers an outstanding 16,508 N·m peak output torque at ratio 100 — 37% more than the NMRV130 and the highest output torque available in any NMRV aluminium worm gearbox. Yet despite this remarkable power density, the die-cast aluminium housing keeps the total unit weight at approximately 40 kg, roughly 55% lighter than an equivalent cast-iron reducer at this torque class. For industries that demand maximum torque in a compact, lightweight, corrosion-free package — from port bulk material handling and heavy crane systems to large chemical reactor agitator drives and primary sludge treatment facilities — the NMRV150 is the definitive solution. The extended IEC flange range, reaching 160B5, covers 11–15 kW three-phase motors and eliminates coupling shafts at the highest power level in the aluminium worm gearbox category. Combined with a 50 mm standard output bore, the NMRV150 provides the most robust shaft interface in the series for direct hollow-shaft mounting on driven sprockets, pulleys, and agitator shafts.<\/p>\n
