Developed to meet growing demand for lightweight, corrosion-resistant drive solutions across paper mills, heavy-duty cranes, and large extruder drives, it combines precision-manufactured worm and wheel geometry with a robust die-cast aluminium A360 housing that delivers natural corrosion resistance without the bulk of traditional cast iron. The NMRV130 accepts IEC motor flanges (90B5, 100\/112B5, 132B5), enabling direct motor-to-gearbox coupling without adaptors \u2014 a significant advantage for machine builders seeking compact, efficient drive packages. With output torques up to <strong>11000 Nm<\/strong> and reduction ratios from <strong>7.5\u2013100:1<\/strong>, the EP-NMRV130 reliably serves paper mills and large-scale manufacturing plants across Australia and international markets. IP65 shaft sealing, six mounting positions, and a smooth baked-enamel finish make it equally at home in food processing washdown areas, outdoor plant rooms, and demanding industrial environments.<\/p>\n<div style=\"clear:both;\"><\/div>\n<\/div>\n<div
