With a solid &Oslash;24j6 input shaft instead of an IEC motor flange, the NRV075 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. 10 kg with 75 mm centre distance and &Oslash;28h6 output shaft, it delivers up to 230 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 mining conveyor drives, industrial agitators, and off-grid field equipment where the solid 24 mm input shaft couples to diesel-hydraulic motors and heavy-duty DC drives.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nrv-worm-gearbox-2.webp\" alt=\"EP-NRV075 solid shaft aluminium worm gearbox foot-mount 75mm
