With a solid &Oslash;14j6 input shaft instead of an IEC motor flange, the NRV050 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. 4 kg with 50 mm centre distance and &Oslash;25h6 output shaft, it delivers up to 84 Nm output torque across ratios 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 water treatment paddle drives, process conveyors, and medium-duty pump mechanisms where VFD-controlled motors require the solid shaft input that IEC-flange reducers cannot provide.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nrv-worm-gearbox-2.webp\" alt=\"EP-NRV050 solid shaft aluminium worm gearbox foot-mount 50mm
