At 48 kg, it represents a significant weight saving over the 70+ kg cast iron equivalents at this torque level, making overhead, wall-mount, and remote-site installations substantially more practical. The 130 mm centre distance and &Oslash;45 mm output shaft handle the heaviest conveyor drives, large industrial agitators, and construction equipment mechanisms in the NMRV range. IEC frames 80 to 210 connect directly. Compatible with PC090 helical pre-stage for extended ratios. Also serves as output stage for NMRV063\/130 double-stage combinations reaching 5000:1 with output torques up to 2430 Nm &#8211; the highest torque achievable in the entire NMRV aluminium range.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/reducers-worm.xyz\/wp-content\/uploads\/2026\/06\/nmrv-worm-gearbox.webp\" alt=\"EP-NMRV130 aluminium worm gearbox 130mm centre distance
