EPNMRV110 Aluminium Worm Gearbox \u2014 Overview<\/h2>\n

The EPNMRV110 is the heavy-duty standard of the EPNMRV aluminium series, purpose-designed for high-torque industrial applications in steel fabrication, metal stamping, and large-scale conveyor infrastructure. At 35 kg and rated to 9.2 kW, it generates up to 660 Nm of output torque with radial force capacity reaching 10,320 N \u2014 placing it firmly in territory previously reserved for cast-iron reducers. Steel plant operators and heavy-machinery OEMs choose the EPNMRV110 because its die-cast aluminium alloy housing offers a 40% weight saving over equivalent cast-iron units, directly reducing structural support costs and simplifying field maintenance. The unit also accepts the widest NEMA motor range in the series: 140TC, 180TC, and 210TC flanges.<\/p>\n
