EP-NMRV110 — Large-Frame Aluminium Worm Gear Reducer for Demanding Drives<\/h2>\n

The EP-NMRV110<\/strong> aluminium worm gearbox is designed for industrial environments where neither weight savings nor output torque can be compromised. With a 110 mm centre distance and maximum input power of 7.5 kW, it generates up to 9,232 N·m output torque — the highest in the standard NMRV range before the NMRV130 — while keeping the housing weight at approximately 22 kg, roughly 40% lighter than equivalent cast-iron units. This combination makes the NMRV110 the benchmark reducer for large municipal sludge handling systems, heavy chemical mixing reactors, quarry and mining conveyor drives, marine deck equipment, and large-scale industrial automation stages. Unlike smaller NMRV units which accept up to IEC 112 motors, the NMRV110 extends IEC flange compatibility to 132B5, covering the complete 5.5–7.5 kW motor frame range and eliminating the need for intermediate couplings on high-power, high-torque drive trains. The NMRV110 also features the largest standard output bore (42 mm) in the sub-NMRV130 range, matching the output shaft diameter of IEC 112–132 motors for direct hollow-shaft mounting.<\/p>\n
