With a solid &Oslash;24j6 input shaft instead of an IEC motor flange, the NRV090 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. 15 kg with 90 mm centre distance and &Oslash;35h6 output shaft, it delivers up to approx. 450 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 renewable energy tracking drives, heavy conveyor systems, and precision positioning applications where the solid input shaft enables direct servo and BLDC motor coupling.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nrv-worm-gearbox-1.webp\" alt=\"EP-NRV090 solid shaft aluminium worm gearbox foot-mount
