EP-NMRV130 — Extra-Large Aluminium Worm Gear Reducer for High-Power Drives<\/h2>\n

The EP-NMRV130<\/strong> occupies the top end of the standard NMRV aluminium worm gearbox range before the NMRV150. With a 130 mm centre distance and 11 kW maximum input power, it produces up to 12,076 N·m output torque at ratio 100 — 31% more than the NMRV110 — while the die-cast aluminium housing keeps the unit weight at approximately 30 kg, roughly 55% lighter than an equivalent cast-iron reducer. This combination makes the NMRV130 uniquely suited to crane and hoist travel drives, heavy municipal sludge handling, large mixing reactors, port bulk material conveyors, and mining industry applications where torque demands are high but lifting heavy gearboxes with overhead cranes is costly and time-consuming. The NMRV130 introduces IEC flange compatibility up to 132B5, covering the complete 7.5–11 kW standard motor frame range, while the enlarged 45 mm standard output bore matches IEC 132 motor shaft diameters for direct hollow-shaft mounting.<\/p>\n
