With a solid &Oslash;28j6 input shaft instead of an IEC motor flange, the NRV110 accepts any motor type via standard shaft coupling &#8211; servo motors, stepper motors, DC brushless, hydraulic motors, and even combustion engine PTO drives. This universal motor compatibility is the defining advantage of the NRV series over the IEC-flange-only NMRV series. At approx. 38 kg with 110 mm centre distance and &Oslash;42h6 output shaft, it delivers up to approx. 650 Nm output torque across ratios 7.5-100:1. The die-cast aluminium alloy housing provides corrosion resistance and thermal efficiency superior to cast iron while saving 30-50% in weight. Purpose-designed for underground mining conveyor drives, heavy industrial agitators, and off-grid heavy equipment where the solid 28 mm input shaft couples to hydraulic motors powered by diesel power packs.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nrv-worm-gearbox-2.webp\" alt=\"EP-NRV110 solid shaft aluminium worm gearbox foot-mount 110mm
